Fault analysis and treatment measures for rotary bearing of ladle turret in continuous caster
The ladle turret of the continuous caster is an important component of the continuous casting production technics，however the slewing bearing is a key component of the ladle turret. The operation and maintenance status of the slewing bearing directly affect the stability of the continuous caster opera⁃tion, once a fault occurs, the production of the whole continuous caster will be interrupted, and it is very difficult to deal with it. In June 2020, it was found that the current of the rotary motor of the ladle turret of No.4 continuous caster in Tianjin New Tiangang United Special Steel Co., Ltd. was abnormally increased, which was judged to be caused by the fault of the rotary bearing. This paper introduces the structural form and operation present situation of the ladle turret of No.4 continuous caster, analyzes the causes of the fail⁃ure of the slewing bearing in the ladle turret, and on this basis, puts forward the use, maintenance and treatment measures to reduce the probability of the failure of the slewing bearing，and ensure the stable op⁃eration of the continuous casting production.
