The relationship between basicity of graphitiferous slag and microstructurcs of both slag and weld metal arc investigated for the same electrode with cast iron.
The nodulizing power of the La-Mg nodulizer and its influences on the chilling sensitivity of nodular cast iron and the property of anti-degeneration were studied.
This paper has described the new process combined with the modification, inoculation and micro-alloyage technology in the manufacturing of high quality high-Cr white cast iron.
When melting cast iron f or rollers in main frequency induction furnace,the recarburization of the molte n iron could be effectively achieved by using new types of recarburizer.
