According to different sintering temperatures, different control tests have been carried out for YG8 crushing and regenerating materials. The alloy samples at different sintering temperatures can be obtained by wet milling, drying, pressing and sintering temperature, followed by the collection and analysis of the physical properties and metallographic observation of the samples. The results show that within a certain range, all physical indexes of cemented carbide broken recycled material increase first and then decrease with the sintering temperature, with the best comprehensive performance at 1 410 ℃ as the sintering temperature.
