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.
