Steel ladle composite collector nozzle and preparation method thereof
The invention discloses a steel ladle composite collector nozzle and a preparation method thereof, and relates to the field of refractory materials. The steel ladle composite collector nozzle comprises a body and a composite body, and the body is prepared from, by weight, 100-120 parts of waste high-aluminum electrical porcelain, 2-8 parts of graphite, 0.2-2 parts of metal aluminum powder, 0.5-5 parts of metal silicon powder, 3-5 parts of phenolic resin, 1-5 parts of silicon carbide and 2-10 parts of biological capsules; the composite comprises the following raw materials in parts by weight: 80-100 parts of waste sliding plate bricks, 1-6 parts of graphite, 1-2 parts of metal aluminum powder, 0.5-5 parts of metal silicon powder, 3-5 parts of phenolic resin, 1-5 parts of silicon carbide and 1-5 parts of biological capsules. The biological capsule comprises a capsule film, bacillus and calcium lactate, wherein the bacillus and the calcium lactate are positioned in the capsule film and are wrapped and covered by the capsule film. The steel ladle composite collector nozzle disclosed by the invention has excellent oxidation resistance, thermal shock resistance, scouring resistance, bending strength, compression strength and stripping resistance, and also has the advantage of low cost.
本发明公开了一种钢包复合下水口及其制备方法，涉及耐火材料领域。本发明的钢包复合下水口，包括本体和复合体，其中，本体包括如下重量份数计的原料：废高铝电瓷100～120份，石墨2～8份，金属铝粉0.2～2份，金属硅粉0.5～5份，酚醛树脂3～5份，碳化硅1～5份，生物胶囊2～10份；复合体包括如下重量分数计的原料：废滑板砖80～100份，石墨1～6份，金属铝粉1～2份，金属硅粉0.5～5份，酚醛树脂3～5份，碳化硅1～5份，生物胶囊1～5份；生物胶囊包括胶囊膜、芽孢杆菌和乳酸钙，芽孢杆菌和乳酸钙位于胶囊膜内并被胶囊膜包裹覆盖。本发明的钢包复合下水口，具有优异的抗氧化性、抗热震性、抗冲刷性、抗折弯强度、耐压强度和抗剥落性能，还具有成本低的优势。
