| 摘 要： | 莱钢物钢厂50tLF采用FHK－3型组装式滑动水口生产铬镍钢，由于长时间浇注和工作温度高，造成下水口和下滑板结缝处穿漏钢事故高，气体弹簧使用寿命低，针对其不足，开发了YHK－2型滑动水口，把下水口改为旋紧方式，气体弹簧布置在滑动水口机构的两侧弹簧箱内，解决了下水口和下滑板间的穿漏钢问题并提高了气体弹簧的使用寿命，使每炉钢生产费用降低138元以上。

| Abstract: | A FHK-3 composite sliding nozzle is used to produce nickel chrome steel in 50t LF at the special plant of Laigang, but long time pouring and high working temperature have caused low life of gas spring and high accident of bleeding out at the joint of the down nozzle and the down slide. Aiming at the deficiency, the type of YHK-2 sliding nozzle is developed. The down nozzle adopts rotary-type, and gas springs are arranged to the both sides of a spring box in the structure of the sliding nozzle, then the question of bleeding out is solved and the life of gas spring is lengthened, and the cost of the production can be decreased by 138 Yuan per heat. |
