Analysis on Factors of Influencing Pulverization of Aluminum Based Ferroalloy and Control Measures
The fa ctors of influencing the pulverization of aluminum based ferroalloy for deoxidization in steelmaking were analyzed by the orthogonal test method.The analytical results showed that the content of Al,C and Ti had different effects on the pulverization resistance time in terms of the alloy,and the ratio of Ti to C was the main factor in determining the pulveri-zation time of the alloy,while this ratrio was more than 10,the alloy had stronger resistance to pulverization.Therefore,if the content of Al in the alloy was in the range from 40％to 60％,the B1 content of carbon and the C4 content of titanium were selected with relatively high performance-priceratio.
