Preparation method for high-strength ferro silicon nitride kiln furniture
The invention belongs to the field of advanced fireproof materials, and relates to a preparation method for auxiliary materials in the firing process of ceramic materials and magnetic materials, and particularly to a preparation method for the high-strength ferro silicon nitride kiln furniture, which comprises the steps of taking iron-silicon 75 alloy powder as raw material, carrying out nitridation and combustion in a flash nitrogenation oven, obtaining an original green body of a cellular loose block ferro silicon nitride, and obtaining a finished product of the ferro silicon nitride kiln furniture after cutting, phenolic resin impregnation, drying and polishing, and the cold crushing strength of the finished product of the kiln furniture is greater than 90 MPa. The preparation method for the high-strength ferro silicon nitride kiln furniture has the beneficial effects that: the preparation method breaks through the preparation method for traditional kiln furniture, the kiln furniture does not need molding or high-temperature sintering, the production process is simple, the ferro silicon nitride kiln furniture prepared by adopting the method can be used repeatedly, the number of use is greater than 200 times, the energy and production cost are saved by a large margin, and the industrialized promotion and application are convenient.
