日本钢管公司和旭玻璃公司共同研制了一种用来调节高炉风口管道内热风流量的陶瓷阀。这种陶瓷阀在钢铁工业中足首次应用。它具有耐热性好、强度高和耐用等优点,将其用于一座有约40个风口的典型高炉进行调节热风流量和改善其分布,能够使高炉的操作稳定,并提高操作效率。这种新型陶瓷调节阀能改善高矿边缘还原气体的循环,同时阀门的构造型式(包括一个连接陶瓷阀用的特殊接头和一个金属传动轴)还利于减少
Nippon Steel and Asahi Glass co-developed a ceramic blast furnace tuyere to regulate the flow of hot air ceramic valve. This ceramic valve is the first application in the steel industry. It has the advantages of good heat resistance, high strength and durability. It is used in a typical blast furnace with about 40 outlets to regulate hot air flow and improve its distribution, stabilizing the operation of the blast furnace and improving operational efficiency. This new ceramic valve improves circulation of reducing gas at high ore margins while the valve configuration (including a special connector for a ceramic valve and a metal drive shaft) also helps to reduce
