As the best supplier of rolling machines in China, we specialize in supplying various types of rolling machines. Rolling machines can be classified according to their purpose, structure and layout. The main types are as follows:
1. By purpose
First rolling machines: used to roll steel ingots into steel billets to provide raw materials for subsequent rolling, including square billet first rolling machines, plate billet first rolling machines, etc.
Sectional steel rolling machines: produce sections such as I-beams and angle steels, divided into rail and beam, large, medium and small rolling machines, and wire rod rolling machines.
Strip and sheet rolling machines:
Hot strip rolling machines (such as thick plate rolling machines, wide strip rolling machines).
Cold strip rolling machines (such as single sheet cold rolling machines, continuous wide strip cold rolling machines).
Steel tube rolling machines: including hot rolled seamless steel tube rolling machines, cold rolled steel tube rolling machines and welded pipe rolling machines.
Special-purpose rolling machines: such as wheel rolling machines, gear rolling machines, screw rod rolling machines, etc.
2. By structure
Two-roll rolling machines: simple structure, divided into reversible type (such as first rolling machines) and irreversible type (such as continuous rolling machines).
Three-roll rolling machines: the workpiece alternately passes through the upper and lower roll gaps, mostly used in section production, and are gradually replaced by four-roll rolling machines.
Four-roll rolling machines: the working roll diameter is small, and the supporting roll bears the pressure, suitable for high-precision strip rolling.
Multi-roll rolling machines: such as six-roll, twelve-roll, twenty-roll rolling machines, used for ultra-thin strip steel or metal foil rolling.
Planetary rolling machines: large reduction ratio (90-95%), suitable for stainless steel strip production.
3. Other special types
Vertical roll rolling machines: vertically arranged, used for side edge processing or width control of plates.
Universal rolling machines: can roll in multiple directions simultaneously, such as H-beam production.
