Testing Research of Liner Stress in Process of Side Pressing

Liner is key parts of equipment of slab side pressing, its main function is supporting the weight of lateral pressure, and are under some impact pressure, which is impact force up to 2000 tons, it make liner frequent breakage in the process of working, an led to entire production line stop, seriously affect the yield and efficiency of hot rolled strip. In order to obtain the reasons of liner fracture, the means of non-linear finite element and test combination were used to test and verify the correctness of finite element model, it is a new solution on how to settle liner breakage by calculation and analysis. The result of study indicate that it can effective increase the output and reduce the cost of cut end for hot-rolled strip, and has obtained the anticipated effect.
