    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 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?
Non bonding wear of rolled material (especially stainless steel strip, etc.)
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: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:Introduction of roll forming process
Roll forming began around 1960s in europe. Because of roll forming, the working model has the advantages of high production efficiency, saving material and increasing product strength.
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:Process mould for rolling forming process
Press forming is an advanced processing technology, and its remarkable characteristics have been paid attention to by the automobile industry at home and abroad.
Q:Material and equipment for roll forming process
Rolling molding is usually through upsetting a blank cold heading machine, thread rolling machine rolling after processed. The equipment for thread rolling and rolling forming includes various reciprocating flat rolling machines, planetary wire rolling machines, two cylindrical roller spinning machines and three cylindrical roller spinning machines.
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.
