Abstract：A mechanical rotating demurring machine was mounted in the run-out roller table of the No.3 extra-thick slab caster. The machine was used for the removal of cutting beards, which were generated during the autogenous cross-cutting of slabs. However, after more than half a year, some shortage appeared in the machine. It was extremely cumbersome to check the number of mounting links between drive shaft and vee-way guide and adjust them, and the drive shaft had problems with insufficient height limiting mechanism. In order to solve the problems of the deburrer, through the research on the scene actual situation and theoretical analysis, a series of deburrer Structure with hammers optimization was made to improve the structure. The design defect of the deburrer with hammers was completely solved. The efficiency of deburring was improved, and the equipment’s maintenance cost was reduced.
