Abstract

The invention provides a high-efficiency slagging agent for a semi-steel tank, and belongs to the technical field of metallurgical auxiliary materials. The invention relates to a high-efficiency slag melting agent for a semi-steel tank. The high-efficiency slag melting agent comprises the following chemical components in percentage by weight: 10-40% of Si + SiC, 5-20% of Fe2O3, 2-15% of Na2O, 0-22% of F, 8-25% of Al2O3, 0-15% of MgO, 1-7% of SiO2 and the balance of impurities. According to the efficient slagging agent, through reasonable matching of the effective chemical components, reasonable utilization of medium-grade and low-grade photovoltaic cutting waste can be achieved, ladle wall bonded slag can be melted and diluted, and the problem that the slag is seriously bonded to a semi-steel tank in the processes of production, transfer and the like of semi-steel is thoroughly solved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical auxiliary materials, and in particular relates to a high-efficiency slagging agent for semi-steel tanks and a preparation method thereof. Background technique [0002] my country's northwest and southwest regions are rich in vanadium-titanium magnetite resources, and its reserves account for more than 95% of China's reserves. In order to make better use of these precious resources, local steel companies use converter oxidation to extract vanadium from molten iron, and the molten iron after vanadium extraction is called semi-steel. Since the silicon and manganese elements in the semi-steel are almost trace amounts, the slag of the semi-steel has the characteristics of high viscosity, poor fluidity, and easy sticking. Semi-steel needs to be transferred to converter steelmaking through semi-steel tanks, and serious slag sticking to tank walls often occurs during the transfer process. Accordin...
