文摘In the process of VHD,argon is blown into the molten steel throuht 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 ladle furnace in Fushun Steel Works ,It is found that when the mean grain size of corundum articles decreases from 760 μm tp 650μm ,the physical properties and service life of the plug are the same as that of importedone ,and can be normally used in the VHD process.
