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?
Generally speaking, to consider the use of rollers in the requirements, including: 1., good wear resistance, 2. toughness, 3., high hardness, 4. hardened layer (easy to wear after repeated repair)
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?
The rolling process using metal at room temperature, cold plastic characteristic, through the rolling tool is the rolling tool to put some pressure on the metal surface, so that the workpiece surface by plastic deformation, the height to the lower tissue slip, the surface roughness decreased.
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.
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?
According to my experience, there should be a problem with the boot encoder (also known as the digital wheel). Thank you. I hope I can help you.
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: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: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.
