摘　　要：研究了硅砂的物化性能对树脂砂的影响。通过实验分析,并经生产现场实践可知:合理选择硅砂的矿物组成、化学成分、合适的粒度级配、酸耗值及角形系数,严格控制含泥量、微粉含量、含水量,能够显著提高树脂砂的综合性能,降低生产成本,减少或消除铸件产品的缺陷。The influence of physicochemical properties of silica sand on the comprehensive performance of resin sand was studied. The experimental analysis and production practice show that the reasonable choice of the mineral composition chemical composition, suitable level of granularity, acid consumption value and angular coefficientof silica sand, and the strict control of the amount of mud, powder and water can significantly improve the performance of resin sand, reduce production costs, reduce or eliminate casting defects in product.
