冲天炉是铸铁熔炼的主要设备,冲天炉熔炼技术水平与铸件质量有密切的联系。过去,我们曾以焦铁比作为考核冲天炉的主要指标,而忽视了铁水温度、铁水质量和能源消耗等重要的技术内容,以致未能正确地评价冲天炉的技术质量水平,使对冲天炉的操作和控制带有一定的盲目性,造成铸件质量低,能耗大,经济效益差。那么怎样才能合理地对冲天炉全面的技术指标都给予定量评价呢?通过在湖北省1983～1984年度举行的全省首届冲天炉熔炼技术质量竞赛中,对39座各种类型冲天炉的考核实践证明,这是一种比较科学的评价冲天炉水平高低的办法。冲天炉熔炼技术质量的考核内容为十六项,涉及熔炼技术、铁水质量、能源消耗和文明生产等,总分为100分。
Cupola is the main equipment cast iron smelting, cupola melting level of technology and casting quality are closely linked. In the past, we used the iron-iron ratio as the main index to evaluate the cupola, while neglecting the important technical contents such as the temperature of the molten iron, the quality of the molten iron and the energy consumption, so that we failed to correctly evaluate the technical quality of the cupola and make the cupola The operation and control with a certain degree of blindness, resulting in low quality casting, energy consumption, poor economic efficiency. So how can we reasonably evaluate the comprehensive technical indexes of the cupola? In the first test of the cupola smelting quality competition held in Hubei Province from 1983 to 1984, the assessment of 39 cupola types Prove that this is a more scientific way to evaluate the level of cupola. Cupola melting technology quality assessment of the content of 16 items, involving melting technology, hot metal quality, energy consumption and civilized production, a total score of 100 points.
