摘要
树脂砂较之传统的粘土砂或水玻璃砂工艺 ,其铸件裂纹倾向增大 ,尤以弥散性微细裂纹更为突出。对照本公司的实际经验 ,谈呋喃树脂砂铸钢件裂纹产生的机理及预防对策。
Comparing with traditional claybonded sand or sodium silicate bonded sand, Resin bonded sand makes great possibility of cracking in castings, especially scattered tiny crack. According to the actual experience of company and relative reference, the mechanism and preventive countermeasure of crack of steel casting are put forward .
