Introduction
使用于炼钢连铸工程的Tundish Open Nozzle是稳定和调节熔钢流量等的作用，决定中间包使用寿命的重要耐火品。
我公司所努力在Zirconia Open Nozzle的研究及提高质量，采用了高品位原材料与高温烧成方式，研发出致密质Nozzle（水口）了.
我公司的水口是抗侵蚀性强，抗热振稳定好会帮助客户的稳定作业。
Layout
Zirconia Nozzle
由于稳定的CaO锆质对熔钢抗侵蚀性强抗热振稳定好.
Well Block
由于Al2O3-SiO2质在热间稳定性强，对膨胀的水口会起支撑作用.
Mortar
由于Al2O3-Cr2O3质的大气上硬化的胶泥，在冷间上结合力强，会吸收在热间上水口的膨胀防止熔钢入侵.
