Carbon-free aluminum-magnesium machine-pressed brick with excellent thermal shock resistance and corrosion resistance and preparation method of carbon-free aluminum-magnesium machine-pressed brick
The invention discloses a carbon-free aluminum-magnesium machine-pressed brick with excellent thermal shock resistance and corrosion resistance and a preparation method thereof. The carbon-free aluminum-magnesium machine-pressed brick is prepared from the following raw materials in parts by mass: 55 to 75 parts of active magnesium oxide coated corundum particles, 15 to 35 parts of corundum fine powder, 1 to 5 parts of active aluminum oxide powder, 1 to 5 parts of calcined aluminum oxide powder, 4 to 10 parts of magnesium-aluminum superfine powder binding agent and 1.5 to 4 parts of water, the active magnesium oxide coated corundum particles are prepared from the following raw materials in parts by mass: 80 to 95 parts of corundum particles, 5 to 20 parts of active MgO micro powder and 3 to 8 parts of Mg salt binding agent, the preparation method of the active magnesium oxide coated corundum particles comprises the following steps: adding the raw materials of the active magnesium oxide coated corundum particles into a granulator, granulating, drying and sieving. The preparation method of the carbon-free aluminum-magnesium machine-pressed brick comprises the following steps: uniformly mixing the raw materials of the carbon-free aluminum-magnesium machine-pressed brick, pressing into a green body, and baking the green body at 150-220 DEG C for 6-12 hours.
本发明公开了一种抗热震和侵蚀性能优良的无碳铝镁机压砖及其制备方法。以质量份计，该无碳铝镁机压砖原料组成包括：活性氧化镁包覆刚玉颗粒55～75份，刚玉细粉15～35份，活性氧化铝粉1～5份，煅烧氧化铝粉1～5份，镁铝超微粉结合剂4～10份，水1.5～4份；以质量份计，活性氧化镁包覆刚玉颗粒的原料组成包括：刚玉颗粒80～95份，活性MgO微粉5～20份，Mg盐结合剂3～8份；活性氧化镁包覆刚玉颗粒的制备方法包括：将活性氧化镁包覆刚玉颗粒的原料加入到造粒机中造粒，干燥，过筛。该无碳铝镁机压砖制备方法包括：将无碳铝镁机压砖的原料混合均匀后压制成生坯，然后将生坯置于150～220℃下烘烤6～12h。
