8th International Congress on Science and Technology of Ironmaking - ICSTI 2018

Laboratory test of removal of titanium from hot metalis developed in different remover, different proportion and different granularity.The suitable remover and parameters for industrial production test are found. At the same time the removable titanium removal device is designed and developed. Industrial test of removal of titanium from hot metalin blast furnace of Shou-gang stock company is developed successful. When the ratio of the remover is 1%, the titanium removal rate of hot metal reaches above 50%. And the temperature drop and slag skimming amount are all within the normal range. There is no effect on the back process. Through this test, the contradiction between high titanium content in hot metal because normal furnace protection and low titanium content in hot metal of silicon steel is solved.
