Development and application of a new carburant material

摘要

Anthracite carburant is adopted to increase the carbon during the steel tapping of the converter of Panggang, however, it is found that the smelting time is long and the yield rate of the carbon is low which severely affect the precision control of the heat composition, so the new type of carbon-manganese alloy carburant is developed and the application effect to the industry is investigated. The results show that this new type carbon-manganese alloy carburant smelting much faster, and the yield of the carbon and manganese are high, the average yield of carbon is 92.95%, which is 7.36% higher than anthracite, the manganese is 93.31%. This new type carburant for increasing the carbon can decrease the temperature of the tapping in the promise of keeping the quality of liquid steel, shorten the logistic time and reduce the cost of steel per ton.
