直接利用高炉铁液浇注铸件是一项十分经济的技术。本文介绍了应用稀土镁合金使高炉铁液经过变质处理后浇注高碳铸铁钢锭模的方法、研完了此类材质的机械、耐热疲劳、抗氧化生长等性能,并且经济及使用寿命方面,与用冲天炉生产的灰铁锭模作了比较,实践表明,不仅锭模使用寿命提高了1～1.5倍,且制造成本大大降低。同时,作者还分析了铸铁锭模破坏的原因,并提出了自己的看法。
It is a very economical technique to directly cast the castings using the molten iron of the blast furnace. This paper introduces the application of rare earth magnesium alloy blast furnace iron liquid after modification of high carbon cast steel ingot mold method, research finished the mechanical properties of such materials, thermal fatigue, anti-oxidation growth and other properties, and economic and service life, and Compared with the gray iron ingot mold produced by the cupola, the practice shows that not only the service life of the ingot mold is increased by 1 to 1.5 times, but also the manufacturing cost is greatly reduced. At the same time, the author also analyzes the reason of cast iron ingot destruction, and puts forward his own opinion.
