Specifications

used to open and level rolled plate, entry the plate into forming machine, and bend to required shape in cold state by rollers.

According to different products, cold forming steel mill is grouped into square pipe mill, steel sheet pile unit, and other units.

Square pipe mill mainly products square and rectangular pipes, using “directly forms to square” technology, equipped with high-frequency induction welder, it can realize one set roller producing all specifications of square and rectangular pipes. Our company can produce square pipe mill the spec. is from square 200mm to 500mm.

Steel sheet pile unit is a specified unit in manufacturing steel sheet piles by taking use of continuous bit by bit flexible forming technology.

Other units can product U-steel, C-shape steel and many other shape steels by changing rollers.

Technical process:

Uncoiling →Hydraulic shear and cross-welding→ Delivering machine →Vertical accumulator→ Pinching and leveling machine →Forming→Flying saw →Runway → Material reverse →Packing → Stoting.

Cold Forming Steel Mill

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: Rigid force, 1000N-3000N, damage to the guide rail of machine tool transmission mechanism, seriously damage the accuracy and life of machine tools.

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?: Non bonding wear of rolled material (especially stainless steel strip, etc.)

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: 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.
