通过透气砖向金属液中鼓入惰性气体是一种重要的精炼工艺,具有搅拌熔池、提高反应速率以及去气去夹杂等作用,其应用日趋广泛。根据冶金动力学理论,精炼效率与气体在金属液中的行为密切相关。为此,有必要研究这类工艺的基础——恒流率条件下非润湿喷孔上气泡的形成及诸因素对气泡尺寸的影响.实验工作 It is an important refining process to blow inert gas into the metal liquid through the breathable brick, and has the functions of stirring the molten pool, increasing the reaction rate and removing gas to the inclusions, and the like, and its application is more and more widely used. According to metallurgical kinetic theory, refining efficiency is closely related to gas behavior in molten metal. Therefore, it is necessary to study the basis of this kind of process - the formation of bubbles on the non-wetting orifice under the condition of constant flow rate and the influence of various factors on bubble size.Experimental work
