The invention relates to a carbon-free brick for a steel ladle and a processing method of the carbon-free brick. The carbon-free brick comprises the following components in parts by weight: 60-75 parts of white corundum particles, 10-20 parts of fused magnesite fine powder, 10-15 parts of aluminum oxide micro powder, 3-6 parts of silicon dioxide micro powder, 5-8 parts of alumina particles, 1-2 parts of hydroxypropyl methyl cellulose and 3-6 parts of a binding agent. The processing method comprises the steps of (1) dissolving the binding agent in water; (2) adding the white corundum particles, the alumina particles and the binding agent into a mixing mill for mixing; (3) adding the fused magnesite fine powder, the alumina micro powder and the silicon dioxide micro powder into a mixer for mixing; (4) adding hydroxypropyl methyl cellulose, and mixing to obtain pug; and (5) baking after compression molding. The steel ladle brick does not contain carbon, is high in purity and does not pollute molten steel. The strength of the carbon-free brick can be improved through cooperative use of the cellulose and the binding agent, mechanical pressing under higher pressure is facilitated, the density of the brick blank is improved, the strength is improved, and meanwhile the production efficiency is improved.
本发明涉及一种钢包用无碳砖及其加工方法，无碳砖包括以下重量份组分：白刚玉颗粒60～75份，电熔镁砂细粉10～20份，氧化铝微粉10～15份，二氧化硅微粉3～6份，矾土颗粒5～8份，羟丙基甲基纤维素1～2份，结合剂3～6份。加工方法包括：(1)将结合剂溶于水中；(2)将白刚玉颗粒、矾土颗粒和结合剂加入混炼机中混炼；(3)将电熔镁砂细粉、氧化铝微粉、二氧化硅微粉加入混料机中混合；(4)加入羟丙基甲基纤维素混炼成泥料；(5)压制成型后烘烤。本发明钢包砖不含碳，纯净度高，不会污染钢水。纤维素和结合剂配合使用能提高无碳砖的强度，便于采用更大压力进行机压，砖坯的致密度提高，强度增大，同时提高生产效率。
