AI Technical Summary
In the ladle argon blowing system, the automatic connection device is easily blocked by steel slag and dust in the high temperature and dusty environment, which leads to the failure of the check valve sealing function, affecting the stability of argon gas transportation and the quality of molten steel refining.
Design a ladle argon blowing filtration device, installed on a ladle support, including a mounting base and a filter assembly. The filter assembly has strip-shaped filter holes, and the mounting base has external threads on its outer circumference for fixing by threaded connection. The filter assembly has multiple first and second filter holes for intercepting steel slag and dust to ensure normal argon delivery.
It effectively intercepts steel slag and dust, prevents check valve from jamming, ensures normal argon delivery, extends the life of filter components, guarantees the stable operation of the ladle argon blowing system, and improves the quality of molten steel refining.
