Dry ramming material for medium-frequency induction furnace and preparation method of dry ramming material
The invention relates to a dry ramming material for a medium-frequency induction furnace and a preparation method of the dry ramming material. According to the technical scheme, 63.0 wt%-78.0 wt% of quartz sand, 12.0 wt%-17.0 wt% of kyanite tailings, 8.0 wt%-13.0 wt% of enstatite and 2.0 wt%-7.0 wt% of oligoclase serve as raw materials, a binding agent accounting for 1.0 wt%-1.5 wt% of the raw materials is added, the raw materials are mixed to be uniform, and the dry ramming material for the medium-frequency induction furnace is prepared. The quartz sand comprises the following main chemical components: greater than or equal to 98.2 wt% of SiO2, less than or equal to 0.2 wt% of Fe2O3 and less than or equal to 0.7 wt% of K2O + Na2O; the kyanite tailings comprise the following main chemical components: more than or equal to 52.0 wt% of SiO2, more than or equal to 37.5 wt% of Al2O3, more than or equal to 6.7 wt% of ZrO2, less than or equal to 0.355 wt% of Fe2O3, less than or equal to 1.5 wt% of K2O + Na2O and less than or equal to 0.2 wt% of IL. The method has the characteristics of environmental friendliness, simple process and low cost; the prepared dry ramming material for the medium-frequency induction furnace is high in mechanical strength, good in chemical stability, excellent in slag resistance and long in service life.
