A mathematical model for the relationship between the softening point and composition is established by analyzing the composition of the ISP(Imperial Smelting Paten) sinters, which has considerably facilitated the observation of the sinters' metallurgical properties, and provided a basis for controlling the operation parameters of ISF (Imperial Smelting Furnace).

通过对烧结块的成分分析,建立软化点与成分的数模关系,直观了解烧结块冶金性能的变化,为密闭鼓风炉技术参数的控制提供重要的生产依据。

The fluid field in slab mould was researched at different structure of submerged nozzle by mathematical model.

采用数模研究了浸入式水口不同结构条件下 ,结晶器内钢水的流动状态 研究表明 ,浸入式水口侧孔的角度对流场影响不大 ,主要是钢水很难充满侧孔 ,且浸入式水口的管壁厚度不够 ,没有导流作用 水口侧孔的面积较小时 ,提高出口面积可减小流出速度 ;当流股充不满出口时 ,扩大出口面积 ,不能减小出口流速 在浸入式水口底部开孔 ,可以有效地起到分流作用 ,高拉速下 ,合适的底孔孔径 ,可以得到满意的流

Using the on-line mathematical model for ignition loss to calculate the slab loss in Baosteel hot rolling reheating furnace is more labor-saving and accurate than using the manual weighing method.

采用计算机在线氧化烧损数模来计算宝钢热轧加热炉钢坯氧化烧损比原采用人工称量的办法既省力又精确,同时还优化了加热炉的燃烧控制,对减少氧化烧损和节约能源起到一定作用。
