研究了型砂温度对铸件品质的影响,分析比较了传统旧砂冷却设备和新型旧砂冷却设备的工作原理和特点。结果表明,真空混砂系统和变频冷却混砂机具有环保、节能、集约等特点,能够更好地控制出砂温度和型砂品质,从而提高铸件性能。
The effect of molding sand temperature on casting quality was studied. The working principle and characteristics of traditional old sand cooling equipment and new old sand cooling equipment were analyzed and compared. The results show that the vacuum sand mixing system and the inverter cooling sand mixer are environmentally friendly, energy saving and intensive, which can better control the sand temperature and molding sand quality, thereby improving the casting performance.
