Low-cost high-temperature carbide furnace push plate and preparation method thereof
The invention discloses a low-cost high-temperature carbonization furnace push plate which comprises 25-40 wt% of roller waste particles, 10-30 wt% of roller waste particles, 10-20 wt% of andalusite particles, 5-10 wt% of roller waste fine powder, 3-6 wt% of kyanite fine powder, 10-20 wt% of alumina micro powder, 3-10 wt% of kaolin and an additional binding agent accounting for 5-10 wt% of the total mass of the raw materials. The preparation method of the low-cost high-temperature carbide furnace push plate comprises the following steps: 1) crushing and screening roller waste into required particle sizes; (2) uniformly mixing various raw materials and an additional binding agent; (3) weighing the prepared materials according to the weight of a single biscuit, pouring the weighed materials into a mold, and molding by using a vibration molding machine or a hydraulic machine; (4) naturally drying the formed biscuit for 1-2 days, and then drying the biscuit in a drying kiln at 100-150 DEG C for 12-24 hours, and (5) keeping the temperature at 1400-1450 DEG C for 4-8 hours to obtain the push plate. The high-temperature carbonization furnace push plate prepared by the preparation method disclosed by the invention has better creep resistance and thermal shock resistance, and the production cost is greatly reduced.
本发明公开了一种低成本高温碳化炉推板，包括：25～40wt％的辊棒废料颗粒，10～30wt％的辊棒废料颗粒，10～20wt％的红柱石颗粒，5～10wt％的辊棒废料细粉，3～6wt％的蓝晶石细粉，10～20wt％的氧化铝微粉，3～10wt％的高岭土，以及占以上原料总质量5～10wt％的外加结合剂。上述低成本高温碳化炉推板的制备方法，包括如下步骤：1）将辊棒废料破碎，筛分成所需的粒度；2）将各种原料及外加结合剂混合均匀；3）将制备好的物料，按素坯单个重量称重后倒入模具中，使用震动成型机或液压机成型；4）成型后的素坯自然干燥1～2天，然后入干燥窑在100℃～150℃下进行12～24小时烘干；5）在1400～1450℃条件下保温4～8h，制得推板。本发明制备的高温碳化炉推板具有较好的抗蠕变性和抗热震性，并大大降低了生产成本。
