湿型造型生产线中,旧砂温度是影响型砂质量的一个因素。热砂冷却虽已有多种方法,但所用设备一般都比较庞大,而且均有不甚满意之处。德国艾里希公司研制成功一种新型真空混砂机,其混砂过程兼有冷却作用。使工艺过程大为简化,而且能使获得的型砂温度和水分都非常稳定。 Wet molding production line, the old sand temperature is a factor affecting the sand quality. Although hot sand cooling has been a variety of ways, but the equipment used are generally relatively large, and are not satisfied with the place. Germany Aili Xi company successfully developed a new type of vacuum sand mixer, the sand mixing process both cooling. So that the process is greatly simplified, but also to get the sand temperature and moisture are very stable.
