Causes Analysis and Improvement Measures of Unscheduled Mould Replacement for the Slab Continuous Caster
Based on the application of the mould for two slab continuous casters each with two strands at the plant site in the Steelmaking Division of HBIS Group Tangsteel Company,the factors leading to unscheduled replacemet of the mould are analysed,the technical measures to reduce the unscheduled replacement frequency of the mould are formula-ted.The practice indicates that by taking various measures such as improving the skill level of maintenance personnel,adding production assisting system,properly adjusting the tightening torque of the bolts fixing the copper plate onto the backplate and copper pad hardness,the control of every step in the entire process of mould copper plate assembly,the probability and frequency of unscheduled mould replacement can be reduced so that the continuous production stability.
