Low-carbon magnesia carbon brick for producing stainless steel by converter and preparation process of low-carbon magnesia carbon brick
The invention discloses a low-carbon magnesia carbon brick for producing stainless steel by a converter and a preparation process thereof. The high-temperature-resistant magnesia brick is prepared from the following raw materials in percentage by weight: 20 to 25 percent of macrocrystalline magnesia with the particle size of 3mm to 5mm, 25 to 30 percent of macrocrystalline magnesia crystals with the particle size of 1mm to 3mm, 17 to 23 percent of macrocrystalline magnesia with the particle size of 0mm to 1mm, 15 to 20 percent of macrocrystalline magnesia with the particle size of less than 0.088 mm, 9 percent of graphite with the grade of not less than-194, 4 percent of premix and 3 to 4 percent of phenolic resin, according to the invention, a plurality of large magnesia crystals with different granularities are proportioned, and are subjected to high-speed mixing and compression molding with the premix, the binding agent and the like, so that the carbon source is optimized, the carbon content is reduced, and the service life of the steelmaking converter is prolonged under the condition that other rational indexes are not influenced.
该一种转炉生产不锈钢用低碳镁碳砖及其制备工艺，其组成原料配比为20％‑25％的粒度为3mm‑5mm的大结晶镁砂、25％‑30％的粒度为1mm‑3mm的大镁砂结晶、17‑23％的粒度为0mm‑1mm的大结晶镁砂、15％‑20％的粒度小于0.088mm的大结晶镁砂、9％的品级不低于‑194的石墨、4％的预混料和3％‑4％的酚醛树脂，本发明通过多种不同粒度的大镁砂结晶进行配比，与预混料进结合剂等进行高速混炼压制成型，优化了碳源，减少碳含量，在保持其他理性指标不受到影响的情况下，提高了炼钢转炉的使用寿命。
