除去用スリツトバーナ。[Scope of Claim for Utility Model Registration] A slit burner for metal removal that is charged from below into a communication hole of a molten metal processing container and melts and removes adhered metal on the inner wall of the communication hole while moving up and down, It consists of an outer tube with a water-permeable structure arranged around the tube, a guide tube with an umbrella-shaped flange screwed onto the tip of the inner tube, and multiple points around the circumference at the tip of the outer tube to surround this guide tube. A burner lid is connected and attached, and the fuel gas introduced from the inner tube is reversed between the guide tube and the burner lid, and the oxygen introduced from between the inner tube and the outer tube is connected to the outer tube and the guide. A slit burner for removing metal, characterized by having a structure having gas injection ports that are inverted between the tube and the gas injection ports that mix and inject the gas downward.

Claims

[Scope of utility model registration request]

A slit burner for metal removal that is charged from below into a communication hole of a molten metal processing container and melts and removes metal adhered to the inner wall of the communication hole while moving up and down, and includes an inner pipe and water flow arranged around the inner pipe. It consists of an outer tube, a guide tube with an umbrella-shaped flange screwed onto the tip of the inner tube, and a burner lid attached to the tip of the outer tube at multiple points around the circumference so as to surround the guide tube. The fuel gas introduced from the inner tube is reversed between the guide tube and the burner lid, and the oxygen introduced between the inner tube and the outer tube is reversed between the outer tube and the guide tube, A slit burner for removing bare metal, characterized in that it has a structure having gas injection ports that each eject a mixture of gases downward.
