DEVELOPMENT OF TECHNICAL AND TECHNOLOGICAL SOLUTIONS TO IMPROVE THE SLITTING PROCESS AT MILL 370 PJSC MMK
The aim is to increase the stability of the MMK’s mill 370 performance, and improve the material yield. There are two approaches to the slitting: by dividing a thick neck in the grooves of the working stand of the mill; by dividing a thin neck in the exit slitting guide after the stand. Technical and technological solutions have been developed to ensure stable rolling and an increase of the yield. Trial rolling was carried out using wear-resistant dividing rollers and the correct groove of the stand 14. The measurements showed that the rolled material obtained after the 15th stand has the correct dimensions and sufficient symmetry.
