Analysis and Prevention of Pulling Inhibition and Stagnation of Slab Casters

For case of pulling inhibition and stagnation of slab casters appeared in one continuous casting department of WISCO, Factors include stress of dummy bar systems, integrated frictional force , compression force and pulling speed control mode are analyzed to get the causes. The case was ultimately changed with countermeasures such as equipment optimizing and technology improving. The stability and productivity of continuous casting was improved obviously as long as more benefit being provided.
