Chromium-free drainage agent formula and preparation method thereof
The invention discloses a formula of a non-chromium drainage agent. The drainage agent is prepared from the following components in percentage by weight: 45%-98% of SiO2, not more than 25% of Gr2O3, not more than 2.5% of Al2O3, not more than 0.8% of Fe2O3 and not more than 0.3% of CaO, the invention discloses a preparation method of a non-chromium drainage agent. The preparation method comprises the following operation steps: step 1, preparation work before production, step 2, burdening operation, step 3, material mixing and stirring process operation, step 4, product drying, step 5, sampling, and step 6, packaging and storage. The drainage agent is a low-chromium drainage agent, waste after use is free of pollution to the environment, the drainage agent conforms to the national environmental protection policy, the drainage agent is harmless to human bodies in the production and use process, in the process of producing detergent steel, particularly molten steel is a steel type with strict requirements for [Gr] and [O], important significance is achieved, O2 <-> in Gr2O3 and SiO2 in the drainage agent is prevented from being reduced into the molten steel, and the drainage agent has good economic benefits through special treatment. The drainage agent is high in refractoriness, small in volume expansion coefficient, capable of preventing high-temperature sintering, good in fluidity and high in self-opening rate.
本发明公开了一种非铬质引流剂配方该引流剂是由以下组分按照重量百分比组成，SiO2：占总量的45％～98％，Gr2O3：不超过25％，A l 2O3：不超过2.5％，Fe2O3：不超过0.8％，CaO：不超过0.3％；本发明公开了一种非铬质引流剂的制备方法，包含以下操作步骤：步骤1，生产前准备工作，步骤2，配料操作，步骤3，混料搅拌工艺操作，步骤4，产品干燥，步骤5，取样，步骤6，包装及储存。本发明为低铬引流剂，使用后的废弃物对环境无污染，符合国家环保政策，生产使用过程中对人体无伤害，在生产洁精钢时，尤其钢水是对[Gr]、[O]要求严格的钢种具有重要意义，避免引流剂中的Gr2O3和SiO2中O2‑被还原到钢水中，经特殊处理，引流剂耐火度高、体积膨胀系数小、防止高温烧结且流动性好，自开率高。
