摘　　要：研制了一种电流直加热动态热压烧结炉,钢模具内衬电绝缘陶瓷片,实现了电流直加热;3个时间继电器控制主电路继电器的开合,实现了动态热压烧结;热电偶测量与温度场模拟相结合确定烧结温度。此烧结炉可实现利用低电压、大电流在短时间内对产品瞬时高温烧结的效果,大大缩短粉末烧结时间,提高生产效率,节约能源。A current heating hot press sintering furnace is developed. Electric insulation ceramic is lined steel molds to achieve the current heating. Three time relays control main circuit relay opening and closing to achieve a dynamic hot pressing. Thermocouple measuring combined with temperature field simulation determine the sintering temperature. Products are manufactured in a short time by using low-voltage and high current which can greatly shorten sintering time, improve production efficiency and conserve energy.
