Abstract

The invention discloses a function protection material for a continuous casting crystallizer for industrial pure iron. The function protection material is prepared from the following raw materials in percentage by weight: 30.0 to 36.0 percent of pre-melting material, 15.0 to 17.0 percent of wollastonite, 9.0 to 12.0 percent of albite powder, 2.0 to 3.0 percent of lithium carbonate, 14.0 to 16.0 percent of fluorite, 2.0 to 3.0 percent of dead burnt magnesia, 3.0 to 5.0 percent of boron glass powder, 2.0 to 4.0 percent of graphite carbon, 2.0 to 4 percent of imported carbon black, 5.0 to 8.0 percent of bauxite and 2.0 to 3.5 percent of binder. According to the casting powder, the heat preservation effect and the melting effect are guaranteed, the problems of recarburization and carburization on the surface of a casting blank are effectively avoided, smooth production is guaranteed, and the surface qualification rate of the casting blank reaches 99% or above.

Description

technical field [0001] The invention relates to the technical field of metallurgical auxiliary materials, in particular to a functional protection material for continuous casting crystallizers for industrial pure iron. Background technique [0002] Continuous casting mold flux, as an important metallurgical auxiliary material to ensure continuous casting, has a significant impact on continuous casting production and slab quality assurance. With the vigorous development of continuous casting technology, the current international continuous casting ratio has exceeded 95%. Industrial pure iron refers to pure iron with an iron content of more than 99% and a carbon content of less than 0.04%, and requires low smelting harmful elements. Industrial pure iron is divided into electrical pure iron (electromagnetic pure iron), raw material pure iron (charge pure iron), and military pure iron. Electric pure iron has good electrical conductivity and good magnetic permeability, and is ma...
