2.前言蠕虫状石墨铸铁这种新型工程材料的研究。国内外都很重视,目前正向深度和广度发展,在应用上也向更广的领域发展。但到目前国外直接用于未经预脱硫处理的冲天炉铁水来熔制蠕铁,还未用到商品性的生产中,而在高硫低温条件下稳定生产蠕铁国内外更少见。本文讨论在高硫、低温下,利用双屑再生铁稳定熔制蠕铁钢锭模(开口6″)及φ400轧机梅花套的工艺及应用效果,过去用灰铁HT20—40,每吨钢模耗最高达18kg,平均15kg,每只梅花
2. Introduction worm-like graphite cast iron this new engineering materials research. At home and abroad are very concerned about the current depth and breadth of development, the application also to a broader area of development. However, at present, foreign countries are directly used for melting vermicular iron without using desulphurization in the cupola furnace, and have not yet used commercial production, while the steady production of vermicular iron at high sulfur and low temperature is more rare at home and abroad. This paper discusses the process and application effect of stable melting of iron ingot mold (opening 6 ") and φ400 mill plummet using double scrap crumb iron at high sulfur and low temperature. In the past, with the use of gray iron HT20-40, the consumption per ton of steel Up to 18kg, an average of 15kg, each plum
