The introduction of coldrollforming section mill
The rolling plate in certainwidth is unfolded and leveled. Then, they are sent in to the forming machine.The steel plate is bent to be the needed form in the cold conditions by usingthe roller.
According to the differentproducts, the cold forming steel mills are divided into square pipe mill, steelsheet pile mill, and other kinds of mills.
Square pipe mill mainly producesthe square and rectangular pipes, all kinds of which in the range of roller productionspecifications can be achieved by using direct forming tectonics and theassisted high frequency welding machine.
Steel sheet pile mill mainlyproduces the steel sheet pile by adopting piecewise arc flexible formingtechnology. Steel sheet pipe mill in our company has reached the top level allaround the word.
Other models can produce U-steel,Hat shape steel, carriage U-steel, C-purlin and other steels by changing the roller

- Q:What is the surface rolling forming machine process?
- Due to the rolling surface of metal plastic deformation, so that the surface microstructure of cold hardening and grain refinement, forming a dense fibrous, and the formation of residual stress, hardness and strength, so as to improve the surface wear resistance, corrosion resistance and compliance.
- Q:Improvement in rolling forming process
- The rolling will produce a hardening layer on the surface of the workpiece. This layer has obvious delamination phenomenon with the internal material, which is easy to cause the surface layer to fall off;
- Q:A roll forming machine, rolling out of the length is always not up to a fixed size, not too small, that is, more than that, what is the cause?
- Maybe there is something wrong with that roller. It rolls out of the wrong angle and the size will be out of order.
- Q:What kind of material and what heat treatment are used for pressing roller (molding, feeding, cutting force, heavy load, heavy load) of sheet steel rolling machine?
- Use 40Cr or 20Cr, Cr12.Cr12MoV, quenching and tempering treatment, think of hardness, high point, carburizing, nitriding, and consider adding lubrication device to extend its service life
- Q:Process mould for rolling forming process
- Rolling forming is more complicated and requires higher than rolling thread. The die design is based on the different shapes of the workpiece, the design of the rolling plate into a cross section or a few sections, can use synchronous type; also can use grading type.
- Q:What is rolling forming processing?
- Ironing the surface of the workpiece with a raised micro wave crest to fill the concave micro troughs, thus changing the distribution of the peaks on the surface, and obtaining smaller surface roughness values.
- Q:Material and equipment for roll forming process
- The most common type of roll forming is reciprocating flat wire twisting machine. Therefore, for the manufacturers of cold heading machines and screw rolling mills, the design of rolling dies is only a matter of design.
- Q:Introduction of roll forming process
- Not only threaded fasteners industry applications, automobiles, bicycles and other industrial sectors also use rolling forming process, processing complex shapes of parts.
