Study on Recarburization by a New Carbon-Manganese Alloy Carburant
In order to solve the problem of long melting time and low yield rate of carbon while blind coal is used to recarburize, a new carburant is developed to replace blind coal. Experiment results show that compared with the blind coal, the new carbon-manganese alloy carburant obtains a high smelting velocity, and the average carbon yield rate is 92.95%, which increase by 7.67%, the yield rate of manganese is 93.31%, which a little higher than other normal manganese alloys. After carbon-manganese alloy is used to recarburize, logistics time and power consumption are saved and the cost of steel-making is reduced by 1.05 ¥/t. In addition, there is little effect on the quality of steel.
