Preparation method of magnesium-erbium-cerium fused fireproof profile

Abstract

The invention discloses a preparation method of a magnesium-erbium-cerium fused fireproof profile, and relates to the technical field of fused fireproof profiles. The preparation method comprises following steps: weighing following raw materials: magnesia, erbium oxide, zirconia, and cerium oxide, wherein in the raw materials, magnesium accounts for 92.5 to 97 parts, erbium accounts for 1 to 3 parts, zirconium accounts for 0.5 to 1.5 parts, and cerium accounts for 1.5 to 3 parts; mixing and evenly stirring the raw materials in a mixing device; adding water, stirring to form a mixed material; drying the mixed material, adding the mixed material into an arc furnace at a time, fusing the mixed material, wherein during the fusion process, a microwave vibration mode is adopted, after the mixedmaterial is completely melted, taking out the electrodes, pouring the solution in the furnace into a profile grinding tool, and cooling. Cerium oxide and erbium oxide are added to improve the toughness and slag erosion resistant performance of the profile; one-time smelting and moulding is adopted, during the fusion process, a microwave vibration mode is adopted, the porosity of the profile is reduced, and the output and quality are both improved.

Description

technical field [0001] The invention relates to the technical field of molten refractory profiles, in particular to a preparation method of a magnesium-erbium-cerium molten refractory profile. Background technique [0002] Refractory materials are most afraid of moisture and water immersion, and are greatly affected by the environment. In actual production and application, environmental factors are not easy to control. Products of traditional technology need to be dried at high temperature before they leave the factory for use. The steps are complicated and greatly increase cost and inconvenience to users. The above problems are technical difficulties that cannot be overcome at home and abroad for many years. [0003] Traditional process: need to go through the ratio of raw material large crystal, magnesium aluminum zirconium crystalline stone, magnesium aluminum crystalline stone - adding binder mixture - pouring into mold - extrusion molding by press - heating and drying ...

AI Technical Summary

Problems solved by technology

[0003] Traditional process: need to go through raw material large crystallization, magnesium aluminum zirconium crystal stone, magnesium aluminum crystal stone for proportioning - adding binder mixture - pouring into the mold - extruding through a press - heating and drying (conditions of 200 degrees Celsius) -It is fired with light oil in the kiln, which has experienced two high temperatures, wasting energy, and the yield per ton is only 70%

[0004] The disadvantage is that it is afraid of moisture and water immersion. It is generally operated and transported to the user immediately after the finished product to avoid deformation of the product.
