摘要
在ＶＨＤ过程中氩气搅拌用的氩气是通过安装在钢包底部的透气砖吹入钢液中的。针对抚顺钢厂引进的ＶＨＤ炉外精炼设备，研制了刚玉质透气砖。当刚玉料平均粒度由７６０μｍ降至６５０μｍ时，试制的透气砖可达到进口透气砖的物理性能及使用寿命的要求，能正常用于ＶＨＤ过程。
AbstractIn the prccess of VHD,argon blows into the molten steel through the porous plugs,which are mounted in the ladle bottom. A new type of porous corundum plug has been developed for the VHD secondary refining apparatus importedby the Fushun Steel Works.It is found that when the average size of corundum particles decreases from 760μm to 650μm,the porous plug has the same physical property and the service life with imported one,So this porous plug can be normally used in the VHD prccess.
