Description

Technical Field

[0002] Scrap steel can be recycled and reused. During the recycling process, a converter is used for processing. An oxygen blowing seat is installed at the bottom of the converter. Blowing processing is achieved by blowing oxygen into the converter to refine the molten steel for steelmaking. However, the current blowing device does not have the function of removing smoke and dust, and does not have the function of monitoring the oxygen flow rate and has multiple oxygen gun blowing functions.

[0003] In the prior art, a Chinese patent document with publication number CN219195021U has been proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a multi-porous oxygen blowing seat specially used for steelmaking with a flow rate monitoring function, comprising an oxygen tank and a base mechanism, wherein a cylinder angle valve is installed on the top of the oxygen tank.

However, this approach can also result in the device lacking protective warning features, leading to oxygen pipelines breaking and damaging after prolonged use. This can lead to oxygen leakage, which can be easily affected by combustibles and high temperatures, causing explosions. Utility Model Content
