Description

Technical Field

[0001] The utility model relates to the technical field of steel casting equipment transformation, in particular to a rod mill lining plate anti-loosening structure. Background Art

[0002] A rod mill is a mill with steel rod grinding bodies loaded in its cylinder. It is a commonly used equipment in the slag-suppressing process of steel production enterprises. The rod mill liner is a component used to protect the cylinder of the rod mill from direct impact and friction between the grinding body and the material. At the same time, different forms of liners can also be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material, which helps to improve the grinding efficiency of the mill, increase output, and reduce metal consumption. The liner of a rod mill generally has as many as hundreds of pieces. Since the liner needs to be replaced after severe wear, it can only be detachably connected to the cylinder. Most of the connection methods currently used are installed and connected with bolts. This connection method requires multiple bolts for fixing. When disassembling and replacing, multiple bolts need to be removed before the liner can be disassembled and replaced. This method has low disassembly efficiency. When faced with the replacement of more liners, the replacement efficiency is low and it is time-consuming. Improvement is needed. Therefore, a rod mill liner anti-loosening structure is proposed.
