摘　　要：造型过程的砂温是影响型砂可操作时间(固化速度)的重要因素,为达到合格的可操作时间,不同砂温下混砂机所用的固化剂种类不同。在气温变化明显的地区,铸造厂会根据季节变化使用多达数十种固化剂,极易造成现场管理混乱及质量的波动。通过研发一种混砂机双固化剂液料系统,自动根据砂温对两种酸值固化剂进行调节,达到合格的可操作时间,从而避免因温度波动造成型砂质量不稳定的状况。During the molding process sand temperature is an important factor influencing the sand operating time or curing speed. To ensure the qualified operation time, the different curing agent is used at different sand temperature. In regions where the temperature changes obviously, tens of curing agents may be used in foundry according to the seasonal change, which easily causes the field management confusion and the quality fluctuation. A double curing agent liquid feeding system was developed to automatically regulate two acid curing agents to obtain qualified operation time according to the sand temperature, thus avoiding unstable sand quality caused by temperature fluctuation.
