1.内容简介炉外精炼是近十年来炼钢技术上的一项新的突破。炉外精炼是建立在真空冶金和反应动力学基础上的,装备设计和研制必须满足以下的要求:能具备同时去氢和脱氧的热力学条件——在真空中精炼;能克服由钢包几何因素(D/H≈1)带来的反应界面小、熔池深度大的动力学障碍——采用吹氩搅拌;能补偿精炼过程中由于造渣,合金化及热损
1. Introduction In-furnace refining is a new breakthrough in steelmaking technology in the past decade. Furnace refining is based on vacuum metallurgy and reaction kinetics. Equipment design and development must meet the following requirements: Ability to have simultaneous thermodynamics of de-hydrogenation and deoxygenation - refining in a vacuum; overcoming the influence of ladle geometric factors D / H ≈ 1) to bring the reaction interface is small, the depth of the pool kinetic obstacles - using argon blowing agitation; to compensate for the refining process due to slagging, alloying and heat loss
