摘要
为提高湿型铸造的铸件质量,控制产生气孔、粘砂、夹砂等铸造缺陷,必须严格管理与控制型砂质量,做到从原材料选择、型砂混制、性能检测与控制到型砂性能综合分析等各环节把关。
For the sake of improving the casting quality in green sand casting and controlling the defects as blow-hole, burning on, scab, etc. engender- ed. the quality of moulding sand must be managed and controlled strictly. It shoud be realized to make ch■at various links from selecting raw materials, prepar- ing moulding sand, testin■ and controlling performance to synthetically analyzing on moulding sand properties, etc.
