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.
