摘　　要：在自动造型生产线生产过程中,型砂性能对铸件质量具有决定性的影响。型砂性能控制是保证铸件质量的重要工艺手段,合理选择原砂、膨润土、煤粉等原辅材料,控制好型砂的水分、紧实率、透气性、湿压强度、含泥量及有效膨润土含量挥发份灼减量和砂温等是自动造型生产线型砂性能控制的关键。应根据造型机对型砂各项性能指标要求,严格控制配套砂处理工艺过程,保证自动造型生产线正常运行并充分发挥其效能。In the process of automatic molding line production, molding sand performance has decisive influence on casting quality. Molding sand performance control is important to ensure the quality of the casting process. A reasonable choice of the original sand, bentonite, coal and other raw materials, good control of molding sand moisture, compaction rate, permeability, wet strength, silt content and effective bentonite content volatilization loi, and sand temperature is the key of automatic molding line control of sand properties. A complete set of sand processing process should be strictly controlled based on the requirements of the molding machine to the performance indicators, so as to ensure the normal operation of automatic molding line and give full play to its effectiveness.
