长水口密封碗主要功能:
Main functions of elongated nozzle sealing bowl
长水口密封碗的使用部位为炼钢连铸上的长水口与钢包下水口之间的链接部位,用来对长水口与钢包下水口之间的链接部缝隙进行密封。从而使在开浇时,避免由于长水口与钢包下水口之间的连接部缝隙而出现进空气现象,保证钢水的冶炼浇铸。
The application area of elongated nozzle sealing bowl is used for the joint parts of continuous-casting elongated nozzle and ladle collect nozzle. The usage is to seal the nozzle gaps, so that to prevent the air into the ladle from the gaps while casting and ensure the scheduled production to run.
长水口密封碗特点:
Characteristics of elongated nozzle sealing bowl
1、本公司生产的长水口密封碗属无水系材料,且加入有特殊的添加剂,其施工后无收缩现象,而且材料本身具有良好的粘性,密封性好;
Elongated nozzle sealing bowl produced by our company, belongs to no-water system material and added with special additive. It has good properties such as no shrinkage after its operation, good adhesion and sealing performance of itself.
2、长水口密封碗高温性能好,在开浇后高温下不粉化、不粘附;
Elongated nozzle sealing bowl has better resistance to high temperature. There is no pulverization and no adhesion after casting.
3、施工容易,操作简单,高温使用后与长水口、钢包下水口能很好的分离。
Easy construction, simple operation and can be well separated with elongated nozzle and ladle collect nozzle after high temperature working.
二、 长水口密封碗使用说明:
Instructions for elongated nozzle sealing bowl
长水口密封碗在炼钢开浇前使用,使用时从纸箱中拿出密封碗,摆放于长水口上,密封钢包长水口与钢包下水口接触部位。
Elongated nozzle sealing bowl is used before casting process. Take out from the carton and place it on the elongated nozzle, to seal joint parts of elongated nozzle and ladle collect nozzle
