  Cold-formed steel equipment, which can be on the material? Cold-formed steel equipment, which is used to produce cold-formed steel, a type of steel. In raw materials, generally, hot rolled or cold rolled steel strips are used as billets, and bending and other operations are performed to obtain cold-formed steels having various cross-sectional shapes and sizes. What kind of cold-formed steel equipment is considered good? Which products or industries can be used for the finished product? Cold-formed steel equipment, its good quality standards, is for the equipment of advanced technology and technology, can facilitate the operation and use, and…

Rolling mill is the cold rolling at room temperature, after cold-drawn, cold-rolled, cold drawn and other cold-worked steel or steel into various types of steel. Advantages are fast forming speed, high output value, without damaging the coating, can be made into a variety of cross-sectional forms to meet the needs of the conditions; cold rolling of the rolling mill can make a great plastic deformation of steel, thereby increasing the The yield point of steel. Cold rolled rolling defects First, although the molding process did not undergo thermal plastic shrinkage, but there are still residual stress in the cross…

Cold rolling mill design types can be divided into many kinds, can meet different processing needs to be customized. According to different standards to distinguish the type of mill. If you choose according to the plate processing, cold-rolling mill used in the processing of sheet metal can be hot-rolled and cold-rolled two, in the precise thickness of the rolling case, the mill can be divided into cold-rolled plate Two types of cold-rolling mills are also available. If you need cold-rolled strip to distinguish cold rolling mills, the rolling mill can be divided into continuous rolling mill and reversing rolling…

Longitudinal welding machine production process is simple, high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than the straight seam welded pipe, the pipe can be used to produce larger diameter welded pipe with a narrower blank, but also the same width of the billet pipe production of different diameters. However, compared with the same length of straight pipe, weld length increased by 30 ~ 100%, and the production rate is low. Therefore, the smaller diameter of most of the use of straight seam welded pipe, large diameter welded pipe are…
