静压造型线型砂质量控制

摘要

High quantities of addition of core sands to molding sand for multiple products production in our molding line has resulted in deteriorative molding sand and batch defect of metal penetration. After adjusting the addition of sand and mix process, stable properties of molding sand have been obtained and quality problems with molding sand and metal penetration of casting defect effectively resolved.%我公司静压造型线因生产品种多,芯砂流入量大,导致型砂性能恶化,铸件出现批量粘砂；通过调整型砂配比及混制工艺,稳定了型砂性能,有效解决了型砂质量问题和铸件粘砂缺陷.
