Channel belongs to the construction and machinery used carbon steel, section steel steel complex, its cross-sectional shape of the groove. 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.

Waist high the same channel, if several different legs wide and thick waist also need to model the right plus abc be different, such as 25 # a25 # b25 # c and the like. Q235B channel specifications mainly used height (h), leg width (b), waist thickness (d) of equal size to represent the domestic channel sizes from No. 5-40, the corresponding height of 5-40cm. At the same height, light channel narrower than the ordinary channels of legs, waist thin and light weight. No. 18-40 for large channel, 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 is different according to the specifications into 5-12m, 5-19m, 6-19m three. Select the range of imported channel length is generally 6-15m. 2 Inspection method ① tensile test method. Commonly used standard test method GB / T228-87, JISZ2201, JISZ2241, ASTMA370, ГОСТ1497, BS18, DIN50145, etc; ② bend test. Commonly used standard test method GB / T232-88, JISZ2204, JISZ2248, ASTME290, Г ОСТ14019, DIN50111 and other. Quality carbon structural steel ① steel beginning of the two figures that the carbon content of steel, the average carbon content of the very few that, for example, the average carbon content of 0.45% steel, steel number "45", it is not a sequence number , it can not be read as 45 steel. ② high manganese content in high-carbon steel, manganese should be marked, for example 50Mn. ③ boiling steel, semi-killed steel and special-purpose high-quality carbon structural steel should last particularly marked in the steel, for example, the average carbon content of 0.1% of the semi-killed steel, the steel No. 10b. ④ high-quality carbon structural steel is based on the chemical composition and mechanical properties of supply. Less sulfur content in the steel, phosphorus and non-metallic inclusions, show quality, even better performance organizational structure, commonly used in the need to go through all kinds of heat treatment of the more important mechanical parts. ⑤ according to different chemical composition, high-quality carbon structural steel and manganese content is divided into ordinary steel and high manganese content steel types. Electrician before its stainless steel preceded by the letter "H", to distinguish it from other types of steel. Such as stainless steel wire for the "H2Cr13", can be distinguished from the stainless steel "2Cr13". ① steel letters and numbers. DR represents the letter head of steel hot-rolled silicon steel electrician, DW represents electrician cold-rolled non-oriented silicon steel, DQ represents electrician cold-rolled silicon steel. Digital ② letter, said after the iron loss value (W / kg) 100 times. ③ steel tail of the letters "G" who expressed at high frequency test; do not add "G" were expressed at a frequency of 50 cycles under test. Such as steel DW470 represents electrical products cold rolled non-oriented silicon steel at 50 Hz frequency of maximum unit weight of iron loss is 4.7W / kg.

Mainly used for construction, the bridge project a higher quality welded structure. Q235A and Q235B difference: the steel are the property of carbon steel. In the national standard GB700-88 in Q235A and Q235B material to differentiate primarily in terms of the carbon content of steel, the material is a material Q235A carbon content between 0.14-0.22%; Q235A material not impact tests, Q235B of but to do normal material impact test, V-notch. Relatively speaking, the material is Q235B mechanical properties of steel is much better than the material is Q235A steel. In general, the steel factory before the finished profiles are made on the identification plate logo. Users can determine the material on the signage is Q235A, or Q235B, or other material. Design pressure P≤1.6MPa; temperature of 0 ~ 350 ℃; plate thickness> = 20mm Q235B Element Content Carbon C: ≤0.12% ~ 0.20% of silicon Si: ≤0.3% Manganese Mn: ≤0.3% ~ 0.7% sulfur S: ≤0.045% P P: ≤0.045% chromium Cr: to allow the residual content of ≤0.30% Ni: to allow the residual content ≤0.30% copper Cu: to allow the residual content of ≤0.30% Note: deoxy method: F, b, Z Q235B channel in March 5th Prime Minister Li Keqiang implemented in the government work report, "Made in China 2025", persist in innovation-driven, intelligent restructuring, strengthening the foundation, green development, accelerate the transition from a manufacturing power to create power, also suggested that the state should develop "Internet + "action plan. This is China's central government Q235B channel mansion once extensive reference to the Internet in the government work report, and highlights the importance of the Internet in economic restructuring in. It is reported, it has approved the "Made in China 2025" plan, the "priority to promote the manufacturing of digital, networked, intelligent" placed in the manufacturing industries upgrading "eight action" of the first to adapt to changes in the global industry. It is also clear from the national level important development direction of China's manufacturing industry over the next 10 years. In fact, the current new round of technological revolution and Q235B channel industrial change and social development is the formation of a historic crossroads, including the United States, Germany, France and other developed countries have put forward the "re-industrialization", Germany's first put forward the "Industry 4.0" is the intelligent, networking, information technology into the manufacturing sector. The "Internet +" is the new driving force of China's economy. So, what is the "Internet +"? Q235B channel popular, the "Internet +" is the "Internet + various traditional industries", but it is not a simple sum of the two, but a "chemical reaction", namely the use of information and communication technology and the Internet platform Internet and traditional industries, the depth of integration, synergies and create new development of ecological, new technology upgrade, the new business model, which is the change in nature, such as the Internet + banks, funds = Internet banking; retail = Internet + e-commerce; Q235B channel Internet + = manufacturing industry 4.0. Reference to "Internet +" would have "IOT (InternetOfThings)", that is all interconnected. IOT promote the "Internet +" can be realized, especially for the manufacturing industry the fourth industrial revolution. In the IOT era that billions of people worldwide are using smart devices, so the "Internet +" is the use of the Internet that all things are connected, the transformation of existing industries, or the connection between the new, or strengthen effect Q235B channel originally connected, either compression level originally connected. In short, when changing the way these connections will bring change to an industry and even subversion. Clearly, the next few years, ten years, with the "Internet +" trend of development, most of the sectors and companies will be forced to turn to or actively converted into Internet companies.
