The Adjustment of Position of Rolling Mills
Rolling mills are heavy machines used in industries for processing metal and other materials by passing them through a series of rolls. They are extensively used in the metalworking industry and come in various forms and sizes, each with different features and capabilities. Rolling mills are used for producing various types of materials including plates, sheets, rods and structural components. The adjustment of position of rolling mills is an important step in order to ensure correct operation and maximize its efficiency.
The adjustment of position of rolling mills should be carried out regularly and any adjustments need to be made precisely and in accordance with the instructions of the machine. Adjustment of the position usually involves adjusting the vertical and lateral position of the upper and lower rollers and the alignment of the rolls to each other. In the vertical plane, the upper roller should be adjusted to a horizontal position while the lower roller should be adjusted to a vertical position. The rollers have to be in line and the distance between the rollers also needs to be checked and adjusted as required. Furthermore, the alignment of the rollers must be checked as well. This is typically done by using a plumb bob to check the position of the rollers relative to each other.
The lateral position of the rollers need to be adjusted as well. This involves the adjustment of the lead screw and the adjustment of the side-shift system. The lead screw adjustment is used to move the rollers either closer together or further apart. The side-shift system can be used to adjust the roll gap, which is the distance between the two rolls. The adjustment of the side-shift usually requires the use of a lever, but it can also be adjusted with a screwdriver.
Once all the adjustments have been made, it is important to check the overall alignment of the mill. This can be done by passing a straight edge along the two rollers and checking for any discrepancies. If any discrepancies are noted, they should be adjusted accordingly. Finally, it is important to check the tension on the rollers, which can be done by using a torsionmeter.
Adjustment of the position of the rolling mills is an important process and should be done regularly. Careful and precise adjustments should be made in accordance with the instructions issued by the machine’s manufacturer. Furthermore, the overall alignment of the mill should be checked and any discrepancies should be adjusted as necessary. Finally, the tension of the rollers should be checked as well. Proper adjustment and maintenance will ensure that the rolling mill operates efficiently and safely.
