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.
By observation and analysis of the test data, changing the plate steel endshield of motor into the disc iron one can improve the rigidness of endshield, and reduce the axial vibration of motor.
