Manufacturers of two-roll adjustable opening hot rolling steel mills

The mill stand consists of a cast stand and a top cover, along with adjusting mechanisms, tie rods, and tie rod locking devices. It offers advantages such as lower manufacturing costs and simple adjustment, making it widely used in ordinary wire, bar, and section steel production lines with less stringent requirements and low construction investment. Two-roll open mill train composition: The mill body, mill base, universal joint shaft, joint shaft support, two-core box, reducer, main drive motor, etc.; The mill body mainly consists of: cast open stand with roll gap adjusting mechanism, roll system, and lower-placed roll gap adjustment pads; According to different roll specifications, the mill body is divided into 550, 520, 450, 400, 365, 325, 280, and 250 specifications.

A rolling mill is a machine that produces plastic deformation of workpieces. It is the executive mechanism in the entire rolling process. Compared with ordinary bottom-adjustment rolling mills, top-adjustment rolling mills are favored by customers due to their stable rolling and small bounce values, thus improving product quality. Especially in ordinary bar materials KI-K4 improves the accuracy of finished products during use. Because the rolling mill's lowering device uses manual operation, the lowering adjustment speed is slow; therefore, the top-adjustment rolling mill requires that the rolling process should not frequently change the rolling variety. Generally speaking, a rolling mill consists of rolls, roll bearings, roll adjusting mechanisms, roll balancing devices, and stands.

1. Rolls: Components that cause plastic deformation of metal.

2. Roll bearings: Support the rolls and maintain their fixed position in the stand. Roll bearings have heavy and variable working loads, so they require low friction coefficients, sufficient strength and rigidity, and easy roll replacement.

3. Rolling mill stand: Consists of two "torii" to install roll bearing seats and roll adjusting devices, requiring sufficient strength and rigidity to withstand rolling forces.

4. Roll adjusting device: Used to adjust the roll gap to achieve the required cross-sectional dimensions of the workpiece. The upper roll adjusting device of the top-adjustment rolling mill is also called the "lowering device".

5. Upper roll balancing device: Used to lift the upper roll and prevent impact when the workpiece enters and exits the rolls.
