基于正交试验法的玻璃器皿钢化工艺参数优化OA

Tempered glassware is highly favored for its superior performance.However,in industrial pro-duction,its tempering performance is greatly affected by process parameters.This study takes glass food preservation plates as the test object,and optimizes the tempering process parameters using the orthogonal test method.The temperature of the final zone of the tempering furnace,the speed of the mesh belt,and the air outlet speed in the tempering zone are selected as the factors,each with three levels.The forming rate and the qualified rate from the cold and hot test served as the evaluation indexes.The results of vari-ance analysis indicate that the tempering temperature has the greatest influence on the forming rate and the qualified rate,followed by the air outlet speed,while the mesh belt speed has the smallest influence.The optimal combination of process parameters is determined as the mesh belt speed of 375 mm/min,the tempering temperature of 655℃,and the air outlet speed of 24 m/s.Under these conditions,the forming rate of the glassware reaches 95.62%,and the qualified rate of the cold and hot tests reaches 90%,which is significantly improved compared with conditions before optimization.
