Embodiment Construction
[0016] The present invention will be specifically described below in conjunction with the accompanying drawings and specific embodiments.
[0017] The oxygen top-blown converter air curtain slag retaining taphole of the present invention has a structure such as figure 1 — Figure 4 shown.
[0018] figure 1 It is a schematic diagram of the main view section structure of the present invention. Molten steel enters the tap hole from the tap hole inlet 1, passes through the tap hole inlet channel 2, the tap hole air cavity channel 4, and the tap hole outlet channel 5, and passes through the tap hole outlet 6 Discharged into the ladle. The high-pressure gas enters the molten steel flow channel of the tapping hole from the high-pressure air flow channel 3. The flow direction of the high-pressure gas forms an angle of 45 degrees with the tapping hole channel. After the high-pressure gas enters the air cavity, a high-pressure air cavity is formed to prevent steel slag dirty. The p...
