人工压棒和滑动水口,是国内外沿用已久的两种漏包操作方式.鞍钢轧辊厂创造的电动操作底漏包法,已使用三年之久,浇铸了两万个以上钢锭模.实践表明,这种方法不仅安全可靠,而且提高了产品质量(采用该法前石墨夹杂废品量为515t/a,采用后降至245t/a,减少废品量270t/a.随着底漏包下注法的普遍推广,石墨夹杂缺陷这一高炉铁水直接浇铸钢锭模的质量关键问题将得到全部解决),获得了显著的经济效益.
Artificial pressure rod and sliding nozzle, is a well-established two kinds of drain operation mode both at home and abroad.The electric operation bottom leakage method created by Anshan Iron and Steel Rolling Mill has been used for three years and has cast more than 20,000 steel ingot molds. It shows that this method is not only safe and reliable, but also improves the quality of products (before using this method, the amount of graphite mixed waste is 515t / a, after which it drops to 245t / a, and reduces the amount of waste 270t / a. The general promotion of law, graphite inclusions defects of the blast furnace hot metal directly cast ingot mold quality key issues will be fully resolved), access to significant economic benefits.
