Q:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
We found differences between strip and hot rolled strip width is below 1000mm, so it can be distinguished by the Ruifeng strip and Wuhan specifications eye coil, as to why some people use a strip coil, it depends on their factory mill can tie what width, this demand is also different.
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Roll, roll grinding after due to severe pressure, taper, makes the school not to the operator in the rolling process of double pendulum regulation increases taper, will cause serious side light waves caused by shape defects, cause strip deviation and broken belt.
Q:What are the raw materials for making strip steel?
Hot rolled carbon steel strip is made of ordinary carbon structural steel, mainly used for cold rolled billets, cold formed steel billets, welded steel pipe billets and bicycles and hardware products
Q:What's the reason for the strip after pickling?
Pickling is only surface rust removal, which will not affect the hardness of the material.
Q:What gas does the shear of the strip weld require for the welder?
Welding equipment includes welding machine and welding auxiliary mechanical equipment. According to the way of welding, it can be divided into two kinds of flash welding and welding.
Q:What does galvanized steel strip A6 mean?
The chemical and chemical reactions between the substrate and the molten bath of the hot galvanized steel pipe are complicated and the corrosion resistant structure is closely alloyed with zinc and iron alloy. The alloy layer is integrated with pure zinc layer and strip steel matrix. Therefore, it has strong corrosion resistance.
Q:What is the difference between strip and coil?
Coil generally refers to the strip width not less than 600mm, can generally be divided into Kaiping steel plate or longitudinal strip, standard and plate together, such as: carbon and low alloy structural steel plates and strips. Strip width is generally less than 600mm.
Q:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
Cold rolled coil (annealed): hot rolled coil obtained by pickling, cold rolling, batch annealing, flattening, and finishingThat is, the biggest difference between hot rolled coil and cold rolled coil is that the heat treatment process is different. (annealing process)Compared to the specific heat roll, the cold-rolled roll has a bright surface and a high degree of finish, but it produces more internal stress and is often annealed after cold rolling.
Q:What is strip steel?
Compared with steel plate, it has the advantages of high dimensional accuracy, good surface quality and easy to use. Widely used in the production of welded steel pipe, cold formed steel billet, used for the manufacture of bicycle frame, wheel, clamp, gasket, spring, cable armored, saw blade, blade, packing iron sheet and so on.
Q:Is there any difference between galvanized steel strip and galvanized sheet?
Broad sense means galvanized steel sheet.
