According to the business community to monitor price monitoring, as of April 24, the material Q235A Specification: 20 # channel steel market price 2514.17 yuan / ton (including tax), from the beginning of the week of 2505.00 yuan / ton (including tax) gained 14.17 yuan / ton (including tax), or 0.37%. Second, the impact factors of products: Since last week, small and medium sized mills have gradually raised the profile ex-week profiles market Anshan Po guidance issued in late April, prices, representing a mid-level disk offer up 100 yuan / ton, since the end of 4 Since the beginning of the downward trend of steel prices remain stable, the latter will shock adjustment. Chain: Upstream, the upstream major iron ore giant BHP Billiton iron ore giants have revealed will of iron ore operations will slow down the rate of expansion of the market for iron ore supply surplus is expected to ease the expected warming, iron ore prices rebounded sharply 11 percent to $ 57.81 a tonne on Wednesday also hit 5.9 percent since October 2012, the largest single increase. Then benefited from the overall rise in iron ore, profiles prices rise, and gradually stabilized. Downstream, the real estate data, real estate investment, development and sales are declining, drag profiles market. According to statistics, in 2015 1--3 months, the national real estate development and investment 1.6651 trillion yuan, an increase of 8.5% nominal growth rate of 1 - down 1.9 percentage points from February. 1--3 months, real estate development enterprises housing construction area 5,840,180,000 square meters, an increase of 6.8%, higher than the 1 - down 0.8 percentage points from February. New housing construction area of ??237.24 million square meters, down 18.4%, a decline of 0.7 percent expansion. Housing area 169.94 million square meters, down 8.2%, a decline narrowed 4.7 percentage points. 1--3 months, real estate sales 182.54 million square meters, down 9.2%, a decline of 1 - narrowed 7.1 percentage points in February. Commercial sales of 1.2023 trillion yuan, down 9.3%, a decline of 1 - narrowed 6.5 percentage points in February. By 2015, real estate investment growth is expected under the new normal will further decline in the real estate market continued to adjust, developers will continue to be the amount of the price change, accelerate destocking. Industry: According to CISA latest data show that as of mid-April, the key steel enterprises this year, the cumulative production of crude steel 169,708,300 tons; total average daily production of crude steel 1.6971 million tons. With the weather warming, widely expected to be close to the end of the decline in steel prices, steel inventory declined. At end-March, the nation's major markets five major social stock rose to 15.22 million tons of steel, the third consecutive monthly increase. However, the situation of each week, the first week of March after peaking 15.98 million tons, was down trend by week, until the second week of April, the steel stocks have declined for five consecutive weeks, fell to 14.65 million tons, has more than 3 In early 1.33 million tons, a decline of 8.32%. Steel stocks continued to fall, indicating that the market is expected to decline late. Macro: China's economic growth since the financial crisis, fell to 7 percent for the first time, the economic downturn has made the crisis the authorities "worried" or future senior Chinese economic reform under heavy acceleration. Chinese Premier Li Keqiang said that China's economic downward pressure is still rising, China needs to face greater economic hardship prepare directional control efforts need to increase, hold steady economic growth, ensuring employment, promoting a basic disk reform. The economic downturn will continue to weigh on commodity weakness.

Sales Hotline: 13678715087 Chen (24 hours patiently look forward with you ......) channel Description: channel is a groove-shaped cross-section steel bar. Sectional shape of the trough-shaped beam. Channel belongs to the construction and machinery used carbon steel, section steel steel complex, a groove-shaped cross-sectional configuration. Channel mainly used for building structure, curtain wall engineering, machinery manufacturing, and other equipment and vehicles. In use, it is required to have good welding, riveting performance and mechanical properties. Channel steel billet produced raw materials for the carbon content of no more than 0.25% carbon steel or low alloy steel billets. Finished channel after hot forming, normalizing or hot-rolled delivery. Its specifications to waist high (h) * leg width (b) * waist thick (d) the number of millimeters expressed as 100 * 48 * 5.3, indicating that the high waist of 100 mm, leg width of 48 mm, thick waist 5.3 mm slot steel, also known as 10 # channel. Waist high the same channel, if several different legs wide and thick waist also need to add abc model the right to be different, such as 25 # a 25 # b 25 # c and the like. Channel main categories: channel sub-normal channel and light channel. Hot-rolled channel steel specifications 5-40 #. After the agreement between the supply of hot alternative channel specifications 6.5-30 #. Channel mainly used for building structure, vehicle manufacturing, construction and other industrial cabinets and other fixed disk, channels and beam often used in conjunction. Channel according to the shape can be divided into four kinds: cold-formed channel equilateral, scalene cold-formed channel steel, cold-formed internal crimping channel, cold-formed steel outer edge of the channel in accordance with the theory, it should be is the channel wing force, that channel should stand instead tummy. Specifications channel setting: channel specifications mainly used height (h), leg width (b), waist thickness (d) of equal size to represent the current domestic channel sizes from 5-40 numbers, that is the appropriate height of 5 -40cm. At the same height, light channel narrower than the ordinary channels of legs, waist thin and light weight. 18-40 large channel number, channel number 5-16 for the medium channel. Import channel indicate the actual size specifications and related standards. Import and export orders generally channel in determining the appropriate carbon steel (or low alloy) steel post to the specifications required by the main use. In addition to the standard number, channel no specific composition and performance series. Channel delivery length divided length, double length of two and a predetermined tolerance values ??in the appropriate standard. The length of the selection range of domestic channel number according to the specifications were divided into 5 -12m, 5 -19m, 6 -19m three. Select the range of imported channel length is generally 6 -15m. Channel Analysis: The first rolling mill in Anyang Iron and Steel Co., Ltd. is the production of 400mm Unit No. angles and channel profiles based units, the annual output of 650,000 tons, of which channel the product specifications for the 638 ~ 1208, producing approximately accounting for 25% of total output. Finished channel of staging uses 1 400t cold shear machine. Channel cut quality for subsequent processing, especially welding quality greater impact, if present at a shear fracture collapse shoulder, burr, tearing, cutting oblique defects, there is a big gap when the docking channel will affect welding quality, especially strength index, resulting in greater security risks. Angang vertical 400mm unit with the pace of production and increase production, said cutting defects more prominent, cutting quality of internal control compliance rate was 94.2%. And cutting edge of life is getting shorter, the average class size is changed once, resulting in increased production costs and labor intensity of workers. To solve these problems, from the process, technical and operational were carefully analyzed, and the corresponding improvement measures, and achieved good results. 1, the cause of the process design capacity of 200,000 units t / a, but now the production reached 600,000 t / a, the production capacity of the cooling bed area very prominent problem of insufficient compared with the production angle, channel cooling rate slower, resulting in cut when the channel temperature is higher, prone to collapse shoulder, burr, tearing and other defects, and a greater impact on the life of the cutting edge. 2, cutting edge design reasons channel cutting edge design is the fundamental basis for the finished pass channel shape shown in Figure 1 (100 # channel, for example). This design is prone to shearing process in the following questions: First, two channel compared with other parts of the shoulder, relatively thick, the required shear force is large, cutting edge wear faster, cutting edge use for some time . This part of the relatively large amount of wear and tear, resulting in a larger gap shoulder, shoulder phenomenon prone to collapse; two legs compared to the waist at the channel, due to the shear angle, when the cutting edge wear, shear legs , the shear quantity is small, the legs cut from the usual cut into a tear, channel leg end surface prone to glitches; the third is on the cutting edge down the slope and channel leg finish pass basically the same, so that when the legs are substantially simultaneously cutting force, shear force is large, cutting edge wear faster, while cutting indentation serious leg side, on the other hand cutting edge after aging, prone to cut part of the channel tear, burr phenomenon more. After the two channels is the main influence cut quality. Improvement In response to these three issues, namely to take the appropriate measures. 1, for the problems of slow cooling bed cooling, mist cooling bed area increased to improve the cooling fan speed cooling bed area, and a double-footer added a set of spray nozzles before shears, scissors lower channel temperature-cut parts, thereby avoiding the high temperature caused by steel shear defects. 2, channel cutting edge design for the existing problems, combined with the actual situation of production, designed in the shape of the cutting edge (100 # channel, for example) shown in Fig. By the width of the cutting edge 100mm instead 99mm, reducing the blade clearance in the horizontal direction, improving the quality of channel cut corners portion; cutting edge corners next arc size from R8mm changed R7mm, improve it onto the The shear amount of overlap, improve channel quality shoulder cut; cutting edge at the top width changed from 79mm 80mm, 97mm replaced by a bottom width of 94mm, the lower leg end cutting edge inclination slope finishing pass less than channel , so that when the legs shearing, the leg, not the bottom up as well as by the force, thereby reducing the shear force, improving cut quality. 3, by performing the actual cutting of the specifications of the channel quality and cut the gap data regression analysis to develop a specification for each specification shear gap, in particular: 63 # channel of 0.20 ~ 0.30mm, 80 # channel to 0.20 ~ 0.35mm, 100 # channel is 0.25 ~ 0.35mm, 120 # channel is 0.25 ~ 0.40mm, and a thickness of 0.20 ~ 1.00mm make different gaskets. Each time you replace the cutting edge, the first measurement of the gap, and then select the appropriate shim, cut the gap to ensure that the process is controlled within the required range. Import and export: Import of channels greater than exports. Simple import and accompanying sub-project to introduce two sets of import and other channels. In recent years, several major ports in China's coastal areas (Dalian, Tianjin, Qinhuangdao, Lianyungang, etc.) in the new, expanded oil, coal, grain and other bulk import and export commodities automatic loading and unloading works, with the main equipment imported at the same time, imports are also large channel increasing. The main producing countries and regions as Japan, Russia and Western Europe. The main exports to Hong Kong and Macao outlet channel. Appearance requirements: channel surface quality and geometry tolerances have specified in the standard. General requirements There shall be no surface defects harmful to spend, do not have a significant twist, the provisions channel waves bend (camber) allowable values ??for the parameters and specifications channel surface shape (h, b, d, t, etc.) values, tolerance values. Channel geometry incorrect main manifestations are: angle, legs spread and legs and the like.
