型砂制备或其工艺系统的效益可用许多观点来判断,其中一个观点认为最重要的标准是防止产生与砂子有关的缺陷。总之,型砂制备的趋势是更好地控制与砂子有关的缺陷、生产率及经济而有效的管理。一、砂控制系统职能 1.型砂制备是一个大系统中的一部分,混砂机是该系统的“心脏”,不适当的混砂会带来不良后果; 2.砂子应冷却到接近室温,允许的最高值决定于型砂性能; The benefits of molding sand or its process systems can be judged on many points of view, with one of the arguments that the most important criterion is to prevent sand-related defects. In summary, the trend toward molding sand is to better control sand-related defects, productivity and cost-effective management. First, the sand control system functions 1. Preparation of sand is a part of a large system, sand mixer is the “heart” of the system, improper sand mixing will have adverse consequences; 2. Sand should be cooled to near room temperature, allowing The highest value depends on the sand performance;
