When the rolls of the wire reducing rolling mill are installed, first wipe the bottom sides of the arch window with washing oil, check the wear condition, replace the necessary wear parts, and then evenly apply glycerin to both sides of the arch window, the flat head of the roll and the bearing box. Adjust the direction of the flat head of the roll to make it consistent with the direction of the slide plate in the shaft connecting sleeve, put on the C-shaped hook and adjust the position of the C-shaped hook lifting ring, so that the roll can be lifted horizontally.

Then move the manual hydraulic cylinder of the bearing bracket, and raise the bracket to keep the connecting shaft horizontal. Use a crane to lift the lower roll horizontally and put it into the window of the archway. The flat head of the roll is inserted into the bearing sleeve, and then the upper roll is loaded into the archway according to the operation of installing the lower roll, and the pressure of the hydraulic cylinder of the connecting shaft bracket is removed, so that the its back to low.

Then follow the opposite steps of dismantling the rolls to complete other project operations; after the replacement of the profile wire rolling mill rolls is completed, the axial adjustment of the rolls, the setting of the roll gap, and the installation in place should be carried out to reduce unnecessary problems during the operation.

In recent years, due to the higher and higher requirements for the surface quality of steel, the oval-round hole type with the characteristics of more uniform deformation and less wrinkles on one side has been widely used, especially in rolling alloy steel. The existing method is designed with the spread coefficient as the basic parameter. This method is difficult to use, especially for alloy steels with multiple steel grades.

For the ellipse-round hole type, first assign the extension coefficient to obtain the area and diameter of the circle at odd lanes, and then assuming the shape coefficient of the ellipse when each even lane crosses, on the basis of the known ellipse parameters before the finished product , the parameters of the previous ellipse can be calculated according to the derived formula. Each ellipse is calculated later.

This is the step for how to fix the rollers on your precision wire rolling mill machine.
