| Abstract: | By means of V_(slag) + Ti + Zn,the composite inoculation to the high-Cr white cast iron can be performed.The "twain-step method " has been implemented inside and exterior furnace,and the classifying process sequence has been marked out in accordance with the energy of inoculated alloy heterogeneity nucleation,which has better effects in controlling the settling out amount of the carbide and improvement of separating out morphology,liquid metal purifying as well as the purified grain boundary and refined grain. |
