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.
本发明公开了一种镁铒铈熔融耐火型材的制备方法，涉及熔融耐火型材技术领域，该制备方法为按重量比称取原料镁砂、氧化铒、氧化锆、氧化铈，其中原料中镁占92.5‑97份，铒占1‑3份,锆占0.5‑1.5份，铈1.5‑3份，将原料在混料器中混合搅拌混匀，加入水，搅拌成料球的混合料，将混合料烘干去水后一次性投入电弧炉中熔融，在熔融过程中采用微波震动模式，待全部溶化后提出电极，将炉内溶液倾倒入型材磨具内冷却，得到所需的耐火型材。该耐火型材加入氧化铈和氧化铒，提高了产品的韧性和抗渣浸冲刷能力，采用一次性冶炼成型并在熔融过程中采用微波震动模式，降低产品开孔率，提高了成品的质量和产量。
