Cold-rolled strip is widely used, such as automobile manufacturing, electrical products, rolling stock, aircraft, precision instruments, such as canned food. Cold-rolled steel sheet is ordinary carbon steel cold rolled sheet for short, also known as cold-rolled plate, commonly known as cold, sometimes mistakenly written as cold rolled plate. Cold plate is made of ordinary carbon steel hot rolled strip, after further cold rolling steel plate having a thickness of less than 4mm. Due to rolling at room temperature, do not produce iron oxide skin, therefore, good cold surface quality, high dimensional accuracy, coupled with annealing treatment, the mechanical properties and process performance are better than hot-rolled sheet steel, in many areas, especially in appliance manufacturing, it has gradually replaced with hot rolled steel sheet. Applicable Grade: Q195, Q215, Q235, Q275; SPCC (Japanese brands); ST12 (Germany grades) Symbol: 1, Q- ordinary carbon steel yield point (limit) of the Code, it is "bent" the first phonetic alphabet case; 195,215,235,255,275- represent their yield (limit) the value of the point, unit: MPa MPa (N / mm2); due to the strength of Q235 steel, ductility, toughness and weldability and other mechanical properties belong to the best of ordinary carbon steel, can better meet the general requirements, so a very wide range of applications. 2, S- steel (Steel), P- plate (Plate), C- cold-rolled (cold), fourth C- commercial (commercial). 3, ST- steel (Steel), 12- ordinary grade cold rolled steel sheet, mark: the dimensional accuracy - Size - breed standard cold-rolled steel plate: Steel - technology standard tag example: B-0.57501500-GB708-88; steel Standard No. Q / BQB402, grade SPCC, heat treatment annealing + formation (S), the central processing status table for Ma D, surface quality of the FB-level trimming (trimming EC, no trimming EM) steel, thickness 0.5 mm, Grade B accuracy, width 1000mm, A-level precision, length 2000mm, A-level precision, accuracy roughness PF.A, labeled as: steel ECQ / BQB 402-SPCC-SD-FB / (0.51000A2000A-PF.

Better surface quality cold-rolled plate. Has good punching performance. Its requirements to ensure that cold-formed and cup test pass, commonly used in the automotive and other industries and coating plate materials. Edit this kind of cold-rolled products segment (1) cold-rolled annealed processed into ordinary; (2) there is galvanizing unit before annealing treatment device galvanizing process; (3) the basic need for processing panel. Common steel CDCM - SPCC (SPCD, SPCE, ST12, ST13, ST14, BLC, BLD, BUSD, BUFD, BSUFD, etc.), but its performance is basically the same. 3, ordinary cold-rolled; 4, galvanized; 5, galvanized: is the use of a continuous coating process to melt aluminum and 55% 43.4% zinc and 1.6% silicon plated onto the steel surface. Features: (1) there is a good durability and longer life compared to galvanized steel; (2) there is a good heat resistance, compared with galvanized steel at high temperatures are less likely to change color; (3) have Good thermal reflective; (4) has a gorgeous silver-white surface; (5) have similar processing properties of galvanized steel and spray performance; (6) has good weldability. Applications: demanding industry with galvanized sheet. 6, tin plating (tin): The Florin Stan type insoluble anode plating tin processing technology. 7, painted; 8, electrical steel (silicon steel). Edit this paragraph technical indicators, performance and specifications of cold rolled sheet has good performance, that is, through cold rolling, you can get thinner, higher precision cold-rolled strip and plate, straight and high surface finish, cold-rolled plate surface clean and bright, easy-to-perform coating processing, variety, versatile, both high and non-prescription stamping performance, low yield point features, so with the use of a wide range of cold rolled sheet, mainly used in the automotive, printing drum , construction, building materials, bicycles and other industries, while still producing the best selection of organic coated steel.

Construction industry which is mainly used in the manufacture of industrial and civil corrosion roof, roof grille; light industry with its manufacturing appliance housing, civil chimneys, kitchen utensils, automobile industry, mainly for corrosion and other car parts manufacturing ; agriculture, animal husbandry do use food storage, frozen meat and fish processing equipment and so on; business is mainly used as a storage and transportation of materials, packaging, and other appliances. (1) higher precision, cold-rolled strip thickness difference of no more than 0.01 ~ 0.03mm. (2) the size of thinner, thinnest cold-rolled strip 0.001mm; now the thinnest hot rolled up to 0.78mm. (3) superior surface quality, cold-rolled steel sheet can even produce a mirror surface; the surface of the hot-rolled sheet, there are iron scale, pitting and other defects. (4) cold-rolled sheet can adjust their school performance and technological properties such as tensile strength, such as stamping performance according to user requirements. Cold-rolled and hot-rolled steel rolling are two different technologies, by definition, cold-rolled steel at room temperature is in the situation rolled, hardness of this steel. Hot-rolled steel is rolled at high temperatures a production process, cold-formed steel section allows local buckling occurs, which can make full use of the bearing capacity after buckling rods; and hot-rolled steel section does not allow local buckling occurs. 2, for different reasons, and cold-rolled steel hot-rolled steel residual stress, so the distribution of the cross section is also very different. Cold-formed steel residual stress distribution in the cross section is curved, and hot rolled steel or welded steel section on the residual stress distribution is a film type. 3, hot-rolled steel of freedom high torsional stiffness than the cold-rolled steel, hot-rolled steel so torsional performance is better than cold-rolled steel. 1, the appearance and surface quality: Because cold hot plate obtained after cold rolling process, but also will make some cold-rolled surface finish so cold in surface quality (such as surface roughness and the like) than the hot plate to well, so if the product order after the painting there is a higher quality requirements, such as coating, generally choose cold, the other hot plate is divided pickling plate and not pickling plate, pickling plate surface due to acid-washed so as normal metallic colors, but not so the surface is not cold cold rolled high, the board will usually surface oxide layer is not pickling with, black hair, or the presence of iron oxide black layer, the popular talk is like roasted over and, if the environment is not good, then usually a little embroidery store. 2. Performance: Under normal circumstances, the hot plate and cold in the mechanical properties of the project is considered no different, although there are some cold work hardening during cold, (but do not rule out the mechanical performance requirements of stringent conditions , it would need to be treated differently), cold is usually slightly higher than the yield strength of the hot plate, the surface hardness is higher, specifically how the need to see the extent of cold annealing. . But no matter how cold annealing intensity is higher than the hot plate. 3, formability, basically due to the performance of hot and cold plate was not too bad, so the factors shaping the performance depends on the difference between the quality of the surface, due to the cold surface quality is better, it is usually in terms of the same material steel, cold than hot plate shaped appearance better.
