    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?
Different from cutting, mirror rolling is a kind of plastic processing. Not only is the rolling workpiece surface roughness moment can reach Ry0.1-0.8 m, and the wear resistance of the surface hardening process has been improved at the same time fatigue strength also increased 30% advantages in cutting can not get.
Q:Improvement in rolling forming process
It is difficult to control the rolling process and can cause waste easily.
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?
Yes, the width of the bearing plate can be a deviation from the length.
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
A movable wire plate, made of the same fixed wire plate, for relative reciprocating motion. Roll forming is the design of different structures on the plate rolling on the workpiece. Roll out all kinds of thread, convex ring, knurling, end chamfering, groove with different width and thickness as well as other required shapes.
Q:What is rolling forming processing?
Rolling process is a kind of pressure finishing, which is a kind of cold plastic characteristic of metal under normal condition.
Q:Material and equipment for roll forming process
Rolling process is a cold forging process, which can be used for rolling and forming a lot of materials. Among them, low carbon steel is a material commonly used in rolling forming, and non-ferrous metal is more suitable for roll forming.
Q:Introduction of roll forming process
With the progress of technology and the development of production, more and more attention has been paid to the roll forming process.
