Machine-pressed unfired magnesia-carbon composite tundish nozzle for tire cord steel
The invention discloses a machine-pressed unfired magnesia-carbon composite tundish nozzle for tire cord steel, which belongs to the technical field of novel refractory materials with a continuous casting function, and comprises a magnesia-carbon bowl part and a magnesia-carbon body, the magnesia-carbon bowl part takes fused magnesia, graphite, an additive and phenolic resin as raw materials, the magnesium carbon bowl part is prepared from the following raw materials in percentage by weight: 85-92% of fused magnesite, 5-10% of graphite, 1-6% of an additive and 4-8% of phenolic resin, and the magnesium carbon body is prepared from the fused magnesite, fused quartz, graphite, the additive and the phenolic resin. The magnesia carbon body is prepared from the following raw materials in percentage by weight: 60-80% of fused magnesia, 8-20% of fused quartz, 8-20% of graphite, 1-6% of an additive and 5-10% of phenolic resin, proper sintering can be achieved by virtue of heat energy in a use environment, a structure with gradient characteristics is formed, the thermal shock resistance of the unfired brick can be improved, and the service life of the unfired brick is prolonged. And meanwhile, the yield of tire cord steel and the quality of molten steel can be greatly improved.
本发明公开了一种帘线钢用机压不烧镁碳复合中包水口,属于新型连铸功能耐火材料技术领域,包括镁碳碗部和镁碳本体,镁碳碗部以电熔镁砂、石墨、添加剂和酚醛树脂为原料,镁碳碗部所用原料的重量百分比组成为:电熔镁砂85‑92%、石墨5‑10%、添加剂1‑6%和酚醛树脂4‑8%,镁碳本体以电熔镁砂、熔融石英、石墨、添加剂和酚醛树脂为原料,镁碳本体所用原料的重量百分比组成为:电熔镁砂60‑80%、熔融石英8‑20%、石墨8‑20%、添加剂1‑6%和酚醛树脂5‑10%,本发明能够借助使用环境中的热能达到适当烧结,形成具有梯度特征的结构,还能提高不烧砖的热震稳定性,同时能够大幅度提高帘线钢的成品率和钢水质量。
