Study on Technological Parameters of Hot Pressing Sintering of Magnetic Abrasive Grains AITranslate
Abstract AITranslate
Effects of the three essential factors of sintering temperature,sintering pressure and heat preser vation time on the preparation of magnetic abrasive grains were investigated. Iron and alumina powder were mixed first by a certain percentage,and then put into pressure sintering furnace for hot pressing sintering. The relationship between magnetic induction intensity and density of the sintered sample was discussed as well as density variation of the sintered sample with different process parameters. The results show that magnetic induction intensity of the sintered magnetic abrasive sample is linearly proportional to its density. with the increase of sintering temperature, sintering pressure and heat preservation time, density of the sample also increases. The optimal conditions are 1 080 ℃ ,46 MPa and 15 rain,and continuing improve ment of the three parameter values cannot significantly change density and magnetic induction intensity of the sample.
