Temperature Field Simulation of Magnetic Abrasive Hot Pressing Process AITranslate
Abstract AITranslate
Based on two-phase composite magnetic abrasive prepared from Fe powder and A12 03 powder, heat transfer model of its hot pressing process is built. Mould temperature field is analyzed by computer simulation,and then the hot pressing process is optimized. Simulation results show that furnace heating rate have a great effect on mould temperature field,and temperature field distribution of the abrasive in dif- ferent mould location is also different. In view of abrasive preparation efficiency and laboratory equipment requirements,the heating rate is determined to be 10~15 ~C/min at low temperature and 5~10 ~C/min at high temperature. And abrasive should be placed in z5 region of the mould,in order to reduce its axial tem- perature difference in the hot pressing forming process and improve its physical and mechanical properties.
