<p>PURPOSE:To improve the working efficiency by specifying the taper effect quantity of each stand of the tandem mill and setting the position of the work roll shift. CONSTITUTION:The taper effect quantity ( h) displaying that the metallic strip to be cold rolled on the tandem mill is in the good state is calculated with the equation. Here, (ah+b) is the constant decided with the roll dimension of each stand, WRT is the value decided with the taper angle (theta) of the work roll, WRdelta is the shift position of the work roll. In order to make this taper effect quantity to be <=1% of each outlet side sheet thickness (h), the work roll shift position is moved to its axial direction and set. Therefore, on the case of the sheet width change and the outlet side sheet thickness change, etc., the taper effect quantity can be easily set and the working efficiency can be improved.</p> |
