it is shown that, for the refining of extra-low oxygen steel under low vacuum, blowing argon through porous plug into molten steel can effectively remove oxide inclusions from molten steel.
the smaller the distance between the porous plug and outlet, the stronger the influence of argon bubbling on the fluid flow characteristics is.
吹气位置越靠近中间包水口侧对流体特征参数的改变效果更佳;
on average there is one porous plug on each square meter, which justifies the choice of the water model dimensions.
平均分布计算大概一平方米面积布置一块透气砖,与水箱模型尺寸相近。
the porous plug brick is the key component for bottom blowing technique in uhp eaf. the application of domestic porous plug brick to uhp eaf was introduced.
