钢包无碳浇注水口及其制备方法
摘要：
本申请公开了一种钢包无碳浇注水口及其制备方法，以质量份计，所述钢包无碳浇注水口的原料包括：刚玉：37～76份；锆莫来石：0～16份；莫来石：0～8份；氧化铝微粉：10～16份；铝酸钙水泥：1～6份。本申请的钢包无碳浇注水口利用莫来石的针状晶体结构和氧化锆的晶格转变特点，提高了钢包无碳浇注水口的材料的热震稳定性能，改善了在使用过程中出现的开裂问题，延长了钢包无碳浇注水口的使用寿命。
摘要（英）：

The invention discloses a steel ladle carbon-free pouring nozzle and a preparation method of the carbon-free pouring nozzle. The steel ladle carbon-free pouring nozzle is prepared from the following raw materials in parts by mass: 37-76 parts of corundum; 0 to 16 parts of zirconium mullite; 0 to 8 parts of mullite; 10 to 16 parts of alumina micro powder; and 1-6 parts of calcium aluminate cement.According to the steel ladle carbon-free pouring nozzle, by means of the acicular crystal structure of mullite and the lattice transformation characteristic of zirconium oxide, the thermal shock stability of the material of the carbon-free pouring nozzle for the steel ladle is improved, the cracking problem occurring in the using process is solved, and the service life of the carbon-free pouring nozzle for the steel ladle is prolonged.
