[0002] With the rapid development of the metallurgical industry, the metallurgical industry has become a disaster area for safety accidents. In order to effectively improve the safety of on-site operations and reduce the probability of accidents, optimizing on-site smelting equipment allows operators to stay away from dangerous sources "unnecessarily". This is one of the best solutions to reduce the occurrence of safety accidents.

[0003] The oxygen blowing process of refining outside the furnace is one of the main locations where safety accidents occur. Usually, the oxygen lance in the oxygen blowing equipment is a consumable. The oxygen lance needs to be replaced after blowing oxygen for several furnaces, and the replacement frequency is relatively high. Currently, when replacing the oxygen lance, the operator is usually required to climb onto the mounting frame of the oxygen lance for replacement. This operation process has a high risk factor and is difficult to operate, posing a threat to the life safety of on-site operators. Utility Model Content
