Analysis and measures for abnormal rotation of roller in the continuous casting sector section
This article analyzes the reasons for the abnormal rotation of the rollers in the 5#sector section of the 1#2150 continuous casting.Through disassembly inspection of the sector section,it is determined that the scratches on the slab are caused by the 6th and 7th rollers of the outer arc of the 5#sector section not rotating.Through analysis,it is concluded that the main reason for the roller not rotating is due to the fracture of the core shaft,which is caused by bearing damage.By analyzing the causes of bearing damage,problems in lubrication,cooling,installation and offline maintenance,use and maintenance,and design stress were pointed out.Finally,suggestions were put forward for online inspection,periodic roller gap measuring instrument,roller repair,roller assembly and alignment,and trial use of new roller shaped sector segments.
