宝珠砂在高锰钢铸件上的使用

Pearl Sand Used in High Manganese Steel Castings

铸钢件的粘砂是一个老问题。目前常用的防粘砂材料有铬铁矿砂、锆英砂和镁砂、橄榄砂等,前两者价格昂贵,后两者使用又有局限性。在目前市场竞争较为激烈的情况下,除了铸件质量外,铸件价格是最重要的因素之一,降低铸件成本一直是企业追求的宗旨。所以寻找一种有效的价格低廉的防粘砂材料仍然是广大铸造工作者的目标。本文主要介绍宝珠砂的成分性能及其在高锰铸件芯砂方面的使用。通过比较,可以达到与铬铁矿砂同样的防粘砂效果,但在降低成本上占优势,故可以在高锰钢铸件芯砂使用上代替铬铁砂。

Steel casting sand burning defect is an old problem.The most commonly anti-sand burning materials include chromite sand,zircon sand,magnesite sand and forsterite sand.The former two have high price and the latter two use limited.ln the current, market competition is fiercer.Apart from casting quality, the casting cost is the most important factor.Therefore, companies have been pursuit of the goal to reduce the cost.To find an effective low-cost material is still the majority target of the foundry workers.This paper mainly introduces the performance of Pearl Sand and the use in high manganese casting core sand.By compared with the chromite sand,it has the same effect on anti-sand burning,but has great advantage in reducing cost.Therefore,it can be used to instead of chromite sand on the core sand of high manganese steel castings.
