Professional Knowledge About Hot Rolling Mill

hot rolling mill

TINVO provides the whole rebar hot rolling line to finish the hot rolling mill process including Reheating Furnace, High-Pressure Water Descaling, Mill Stands, Flying Shear, Cold Shear, Cooling Bed, Packing and Collection Machine, Electric, Air, Lubrication System, etc.The blank metal sheet will be rolled, rolled, and strongly extruded into various types of pipe fittings, flat iron, square steel, angle steel, and metal rolling mills such as steel. Among them, hot strip mills are the most common.

Hot Rolling Mill Procedure:

Scrap steel —-melting—- casting—-mold unloading—-sorting—–deliver to reheating furnace—-heating to 1150~1200°C—- come out furnace—- rolling—- finished product —-packing

2. The main equipment includes Reheating Furnace, High-Pressure Water Descaling, Mill Stands, Flying Shear, Cold Shear, Cooling Bed, Packing and Collection Machine, Electric, Air, Lubrication System, etc.

3. The whole line realizes computer control and reached advanced international standards.

Short-Stress Rolling Mill

The short-stress rolling mill is also called the non-stand houseless rolling mill, a section rolling mill with a short-stress line of the working machine.
The shorter the stress line in the mill stand, the smaller the amount of elastic deformation generated, the greater the rigidity of the rolling mill and the higher the precision of the rolled product. When used as a section rolling mill, it does not only have a high radial rigidity but also has high axial rigidity.

SY model high rigidity rolling mill is a new type of houseless short-stress rolling mill, suitable for small and medium-sized rolling mill renovation, and also for small continuous rolling and semi-continuous rolling plants. For example, in a small semi-continuous rolling mill with an annual output of 150,000 to 200,000 tons, 1202 and 1502 continuous casting billets are used, rough rolling mill is with the roll diameter is Ф500mm×2, and the rolled parts after cutting head by flying shear enters the diameter Ф350×4 and the diameter Ф300×4 continuous rolling mills.

Φ200-650 Hot Rolling Mill Machine

Φ200-650 Hot Rolling Mill Machine

Φ250 rolling mill machine uses the roll of 235-275mm diameter, the roll neck has a diameter of 150mm and the working surface length of roll is 500-700mm. The larger feeding billet is 60*60mm. The rolling mill is mainly used for rolling small steel bars and adopts a three-roll working machine base. The rolling mill is consists of three basic parts: the motor, the transmission and the actuator.

The configuration of Φ200-650 Hot Rolling Mill Machine is electric motor – gear reducer – gear housing – rolling mill. The rolling mill reducer is with a center distance of 600-700mm. Since the steering and rotational speed of the rolls are irreversible, the prime driven power applies a high-speed AC main motor with a lower cost. Considering that the rolling load is very uneven, a flywheel is added between the gear reducer and the motor in order to balance the motor load. The purpose of the gear housing is to transmit torque to the work roll. Three cylindrical herringbone gears of equal diameter are arranged in a row on the vertical plane of a closed box. A reliable shaft coupling is installed between the gearbox and the gear housing. The plum shaft coupling is used in the main coupling.

Φ200-350 rolling mill is the equipment of metal hot rolling mill process, which mainly refers to 2 hi roll reversible rolling mill and 3 hi roll reversible rolling mill. The working structure is composed of mill rolls, roll bearings, rolling mill guides, rack, rail seat, roll adjusting device, upper roll balancing device, and roll changing device.

Φ650 rolling mill is generally used as a cogging machine in the rolling mill production line. It is used to roll the slab introduced from the furnace to obtain the desired shape, size, texture and properties, for the lower mill to bite-in. Because the rolled parts just coming out from the heating furnace has the characteristics of high temperature, good plasticity, low deformation resistance, large the pressing amount of the cogging machine (generally up to 50%), the roll of rolling mill is large, and finally the rolling mill roll has good performance and no residual stress, no bubble, small crystal grain, dense inside texture.
