Lime brick for steel ladle slag line and processing technology
The invention discloses a lime brick for a steel ladle slag line and a processing technology, and the formula comprises the following components in parts by weight: 80-85 parts of natural lime, 1-2 parts of inhibitor, 1.8-2.2 parts of industrial paraffin, 0.6-0.8 part of phenolic resin and 1.5-2 parts of waterproof wax. The inhibitor is an octadecyl trichlorosilane inhibitor; the processing technology of the lime brick for the steel ladle slag line comprises the following steps: step 1, weighing raw materials; step 2, screening; step 3, crushing; step 4, heating; step 5, stirring; step 6, wrapping; step 7, brick pressing; step 8, sintering; step 9, performing waterproof treatment; according to the invention, the calcareous refractory brick is adopted to replace a magnesium-carbon brick for the ladle slag line, so that the service life of the slag line brick is prolonged, the frequency of replacing the slag line brick is reduced, the ladle turnover rate is improved, the material consumption is reduced, and the pollution of carbon to molten steel is reduced.
本发明公开了一种钢包渣线用石灰砖及加工工艺，配方包括：天然石灰、抑制剂、工业石蜡、酚醛树脂和防水蜡，各组分的重量份数分别是：80‑85份的天然石灰、1‑2份的抑制剂、1.8‑2.2份的工业石蜡、0.6‑0.8份的酚醛树脂和1.5‑2份的防水蜡；所述抑制剂为十八烷基三氯硅烷抑制剂；一种钢包渣线用石灰砖的加工工艺，包括以下步骤：步骤一，原料称取；步骤二，筛选；步骤三，粉碎；步骤四，加热；步骤五，搅拌；步骤六，包裹；步骤七，压砖；步骤八，烧结；步骤九，防水处理；该发明，采用石灰质耐火砖替代钢包渣线用镁‑碳砖，提高渣线砖使用寿命，减少了更换渣线砖次数，提高钢包周转率，减少材料消耗，以及降低碳对钢水的污染。
