【Abstract】 The crystal wheel plays an important role of to shaping trapezoidal slab and to ensuring continuous production conditions.Its life becomes a bottleneck of restricting production.The temperature field of the crystal wheel was simulated by the application of the finite element method.By coupled analysis,the thermal stress is the important factor to affect the service life of the crystal wheel.Based on coupled analysis,starting from the optimization of the design principles and methods,making use of ANSYS DX optimization tools,the wall thickness of the crystal wheel have been optimized.The results showed that it can meet the basic performance requirements of the crystal wheel,and the optimization effect is obvious.The effective method was put forward to improve service life of the crystal wheel.At the same time,it was attempted also to optimize structure of similar crystal wheel.更多还原
