Press-in material for blast furnace hearth
The invention relates to the field of refractory materials for an iron-making blast furnace, in particular to a press-in material as filler for gaps of a blast furnace hearth. The press-in material comprises anthracene oil, SiC powder, graphite powder and an auxiliary binder. A preparation method of the press-in material comprises the following steps: the anthracene oil is added to a mixed material of the SiC powder and the graphite powder, the weight ratio of the anthracene oil to the mixed material is 3:1, and the mixture is heated and distilled; after distillation, samples are taken for component test, and the samples are taken out and cooled after the test result is qualified. The press-in material has good flowing property, the heat conduction coefficient is close to that of a carbon brick material, the press-in material can solidify quickly at a high temperature to block the gaps, so that gas leakage of the blast furnace hearth can be avoided, the thermal conductivity of the blast furnace hearth can be enhanced, and the press-in material has higher practical value.
