熔炼方法和熔炼设备的发展前途取决于一系列因素,这些因素包括金属质量,原料资源和动力资源,经济费用等。由于向机器零件和机械零件提出的要求日益提高,因而需要进一步提高作为结构材料的铸铁质量,减少铸铁中有害杂质的含量,提高铸铁组织和强度的均一性。在铸造生产的原料供应中,出现了提高炼钢生铁份额以取代铸造生铁的趋势,在高炉生
Melting methods and smelting equipment development depends on a series of factors, including the quality of the metal, raw materials and power resources, economic costs. Due to increasing demands on machine parts and mechanical parts, it is necessary to further improve the quality of cast iron as a structural material, to reduce the content of harmful impurities in cast iron, and to improve the homogeneity of the cast iron structure and strength. In the supply of raw materials for foundry production, there has been a tendency to increase the proportion of pig iron in steelmaking to replace cast iron,
