Mullite runner brick prepared from raw alumina powder and preparation method of mullite runner brick
The invention discloses a mullite runner brick prepared from raw alumina powder and a preparation method of the mullite runner brick. The mullite runner brick comprises the following raw materials in percentage by weight: 40-60% of alumina particles with the content of Al2O3 being 75-85%; 15 to 30% of raw alumina fine powder with the Al2O3 content of 69 to 71%; 5-10% of calcined alumina fine powder with the content of Al2O3 being 75-85%; 10 to 25% of raw clay fine powder with the content of Al2O3 being 25 to 35%; according to the mullite runner brick, expensive mullite is not used as a raw material, but cheap raw alumina fine powder is used, and the mullite runner brick of which the porosity is 19-25%, the compression strength is 60-120Mpa, the refractoriness is greater than 1800 DEG C and each index is higher than that of the national industrial standard YB/T4637-2018 mullite runner brick is produced at low cost by controlling the use amount of each raw material; and the production cost of the mullite runner brick is greatly reduced.
本发明公开了一种用生矾土粉制造的莫来石流钢砖及其制备方法，所述莫来石流钢砖包括以下重量百分比的原料：Al2O3含量为75‑85％的矾土颗粒40‑60％；Al2O3含量为69‑71％的生矾土细粉15‑30％；Al2O3含量为75～85％的熟矾土细粉5‑10％；Al2O3含量为25～35％的生粘土细粉10‑25％；此种莫来石流钢砖没有使用昂贵的莫来石作为原料，而是使用了廉价的生矾土细粉，通过控制各原料的用量，低成本的生产出了气孔率19‑25％，耐压强度60‑120Mpa，耐火度大于1800℃，各项指标均高于国家行业标准《YB/T4637‑2018莫来石质流钢砖》的莫来石流钢砖，大大降低了莫来石流钢砖的生产成本。
