Environment-friendly refractory material for converter tapping hole and preparation method thereof
The invention relates to an environment-friendly refractory material for a tapping hole of a converter and a preparation method of the environment-friendly refractory material, and the environment-friendly refractory material is prepared from the following raw materials in parts by weight: 60-80 parts of fused magnesite with the granularity of more than 3mm and less than or equal to 5mm, 40-55 parts of fused magnesite with the granularity of more than 1mm and less than or equal to 3mm, 20-25 parts of fused magnesite with the granularity of more than 0mm and less than or equal to 1mm, 2-5 parts of crystalline flake graphite fine powder, 1-3 parts of metal aluminum powder and 1-2 parts of silicon powder, 2-4 parts of furfuryl alcohol modified phenolic resin and 0.1-0.3 part of a high-temperature curing agent. According to the refractory material, furfuryl alcohol modified phenolic resin is adopted as a binding agent, the content of free phenol and free phenol is reduced, and then generation of harmful substances is reduced.
本发明涉及一种环保型转炉出钢口用耐火材料及其制备方法，由下列重量份数的原料制备而成：3mm＜粒度≤5mm的电熔镁砂为60～80份，1mm＜粒度≤3mm的电熔镁砂为40～55份，0mm＜粒度≤1mm的电熔镁砂为20～25份，鳞片石墨细粉为2～5份，金属铝粉为1～3份，硅粉为1～2份，糠醇改性酚醛树脂为2～4份，高温固化剂0.1～0.3份。该耐火材料采用糠醇改性酚醛树脂作为结合剂，减少游离酚和游离醒的含量，进而减少有害物质的产生。
