Production process and production equipment of high-stability fused cast zirconia-corundum brick
The invention discloses a production process and production equipment for a high-stability fused cast zirconia-corundum brick. The preparation method comprises the following steps: preparing a mixture, melting, casting, and carrying out heat preservation annealing, and demolding, wherein the ingredients comprise the following components in parts by weight: 35-40 parts of ZrO2+HfO2, 2-14 parts of SiO2, 1.2-1.6 parts of Na2O, 0-3 parts of rare earth and the balance of Al2O3, and the total weight parts of the ingredients are 100 parts; the ingredients comprise clinker and raw materials in the same proportion, the clinker is a block, the particle size of the clinker is 3-8cm, and the raw materials are powder with the particle size of 0.05-1.5 mm; the clinker accounts for 10-30%; in the meltingprocess, 1/2-3/5 of molten materials are reserved in a furnace body, and the clinker is directly poured into the center of the furnace body through a hopper; the raw materials are subjected to microwave heating before entering the furnace body; the lowest point of the raw materials entering the furnace body should be above the highest liquid level in the furnace body, and the distance between thelowest point and the highest liquid level is 1/2-3/4 of the distance between the highest liquid level and the reserved liquid level; and the included angle [alpha] between the direction of the raw materials entering the furnace body and the horizontal liquid level is 30-60 degrees. According to the production process and production equipment, the melting efficiency can be effectively improved, the uniformity of feed liquid components is improved, and the energy consumption is reduced.
一种高稳定性熔铸锆刚玉砖生产工艺及生产设备，包括混合料配制、熔化工序、浇铸工序、保温退火工序、脱模加工工序，配料按重量份计算ZrO+HfO35‑40份，SiO12‑14份，NaO 1.2‑1.6份，稀土0‑3份，AlO作为余量将配料补足至100重量份；配料中包含熟料和生料，二者配比相同，熟料为块状物，粒径3‑8cm，生料为粉料粒径0.05‑1.5mm；熟料占比10‑30％；其中熔化工序：炉体中保留1/2‑3/5的熔融物料，熟料通过料斗直接倒入炉体中央处；生料在进入炉体前进行微波加热；生料进入炉体的最低点应该在炉体内最高液位上方，其最低点与最高液位之间的距离是最高液位与保留液位之间距离的1/2‑3/4；生料进入炉体的方向与水平液位之间的夹角α为30‑60度。该工艺和设备能够有效提高熔融效率，提高料液组份均匀性，降低能耗。
