Molding process of desulfurization stirring paddle
The invention discloses a forming process of a desulfurization stirring paddle, which comprises the following steps: S1, weighing and proportioning: weighing and proportioning a casting base material and an additive; s2, the castable base material comprises 65-75% of M70 sintered mullite, 5-15% of flint clay, 5-15% of micro powder, 1-5% of silicon carbide and 1-5% of pure calcium aluminate cement; s3, the additives comprise, by weight, 0.05%-0.2% of a water reducing agent, 0.02%-0% of an anti-explosion agent and 1%-5% of heat-resistant stainless steel fibers. By using 65% or above of M70 sintered mullite and controlling the ratio of medium-temperature strength to high-temperature strength to be 1.1-1, thermal shock resistance can be further enhanced, the medium-temperature strength and the high-temperature strength during pouring are controlled to be 100-175 Mpa, so that the product can have good anti-scouring performance, and by means of a large amount of aluminum oxide in a pouring base material, the thermal shock resistance of the product can be improved. The thermal shock resistance can be further enhanced through the high thermal conductivity and the low thermal expansion coefficient of silicon carbide, so that the thermal shock resistance of the product is high, and the product has good erosion resistance and erosion resistance.
本发明公开了一种脱硫搅拌桨的成型工艺，其步骤如下：S1、称重配比，称重配比包括有浇注基料和添加剂；S2、浇注料基料包括有：M70烧结莫来石65‑75%、焦宝石5‑15%、微粉5‑15%、碳化硅1‑5%、纯铝酸钙水泥1‑5%；S3、添加剂占浇注基料的重量比为：减水剂0.05‑0.2%、防爆剂0.02‑0,5%、耐热不锈钢纤维1‑5%。本申请通过使用65%以上的M70烧结莫来石，通过将中温强度与高温强度之比控制在为1.1‑1，能够进一步加强抗热震性，通过将浇注时的中温强度与高温强度控制在100‑175Mpa，使得产品能够具有良好的抗冲刷性，通过在浇注基料中大量的氧化铝，通过碳化硅的高导热性以及低热膨胀系数能够进一步加强抗热震性，使得产品的抗热震性强，并且具有良好的抗冲刷性与抗侵蚀性。
