按热力学的基本理论将钢包真空吹氩搅拌过程分为三段,即1)氩气由透气砖进入钢液为绝热膨胀;2)氩气在钢液中升温至与钢液同温的等压膨胀,3)氩气泡在重力作用下上浮膨胀。以上三个过程向钢液提供的搅拌功率为 According to the basic theory of thermodynamics, the ladle vacuum argon stirring process is divided into three sections, that is, 1) the argon enters the liquid steel through the air-permeable brick for adiabatic expansion; 2) the argon gas is heated in the liquid steel to the same temperature as the liquid steel Expansion, 3) Argon bubbles float up under gravity. The above three processes to provide molten steel mixing power
