铸造生铁氧化脱磷的试验研究
A detailed discussion was made on the market demand for the hi-quality iron castings,especially the ductile iron castings,ADI castings and vermicular iron castings,and the compositions requirements for the hi-quality foundry pig irons including hi-purity pig irons used for production of above castings.
论述了优质铸铁件,特别是球铁、等温淬火球铁(ADI)和蠕铁件的市场需求及生产这些铸件必需的优质铸造生铁(包括高纯生铁)成分要求;指出优质铸造生铁大都是小高炉生产的,由于国家有关部门下令关闭200 m3以下的高炉,造成优质铸铁件必需的原材料缺乏危机;建议国家有关部门均衡考虑制造业中各行业的发展,有计划地落实铸造生铁,特别是优质铸造生铁和高纯生铁的生产和供应问题。
