Spinel-periclase castable for electric furnace door and preparation method of spinel-periclase castable
The invention relates to a spinel-periclase castable for an electric furnace door and a preparation method of the spinel-periclase castable. The spinel-periclase castable is prepared from the following raw materials in parts by weight: 60-75 parts of sintered spinel, 25-30 parts of magnesite clinker, 2-6 parts of calcium aluminate cement, 2-6 parts of silica fume and 1-5 parts of alumina ultrafine powder. The spinel-periclase castable is prepared by mixing, casting molding, curing, drying and sintering. According to the castable produced by the invention, the magnesium oxide-rich spinel aggregate, the sintered magnesia fine powder and the amorphous spherical alumina ultrafine powder additive are innovatively introduced. The spinel-periclase castable disclosed by the invention has the characteristics of strong anti-scouring capability, good thermal shock resistance, long service life and the like, and has a good application prospect.
本发明涉及一种电炉炉门用尖晶石‑方镁石浇注料及其制备方法，以重量份计,包括以下原料：烧结尖晶石60‑75份，烧结镁砂25‑30份，铝酸钙水泥2‑6份，硅灰2‑6份，氧化铝超细粉1‑5份，经混料、浇注成型、养护、干燥、烧成，制备尖晶石‑方镁石耐火浇注料。本发明生产的浇注料通过创新地引入富氧化镁尖晶石骨料和烧结镁砂细粉以及非晶态球状的氧化铝超细粉添加剂。本发明的尖晶石‑方镁石浇注料具有抗冲刷能力强，抗热震性能好，使用寿命长等特点，具有良好的应用前景。
