[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] Example 1: A novel slag outlet for an oxygen-enriched side-blown smelting furnace, see Figures 1 to 4 , including a slag discharge channel 1, a U-shaped side plate 3, an end baffle 4 and a copper coil 2;

[0026] Two U-shaped side plates 3 are respectively welded to both sides of the slag discharge channel 1; wherein, the inner cavities of the two U-shaped side plates 3 face outward; two end baffles 4 are respectively welded to the inlet and outlet ends of the slag discharge channel 1; and two copper coils 2 are respectively arranged in the inner cavities of the two U-shaped side plates 3.

[0027] The utility model has the advantages of arranging a slag discharge channel 1, a U-shaped side plate 3, an end baffle 4 and a copper coil 2, with a large opening to prevent slag hanging, cooling water flowing through the copper coil 2 for cooling to prevent the slag discharge channel 1 from being deformed, and slag gushing when the slag outlet is blocked or burned, thereby protecting the personal safety of employees, and solving the problem that the slag outlet has a small aperture, the slag outlet pressure is high when slag is discharged and oxygen is burned, and slag gushing is easy to occur, causing harm to on-site operators.

[0028] Specifically, inclined sections 101 are respectively provided on both sides of the bottom of the inner cavity of the slag discharge channel 1, which are less likely to be blocked by slag than right-angle sections.

[0029] Furthermore, the opening shape of the end baffle 4 is consistent with the inlet and outlet shapes of the slag discharge channel 1, and does not affect the slag feeding and discharging.

[0030] Furthermore, an inlet pipe 201 is welded to the inlet end of the copper coil 2, and an outlet pipe 202 is welded to the outlet end of the copper coil 2. The inlet pipe 201 and the outlet pipe 202 are respectively penetrated and welded to the outer end of the top of the U-shaped side plate 3. The inlet pipe 201 is connected to the external cooling water inlet pipeline, and the outlet pipe 202 is connected to the external return water pipeline. The cooling water passes through the three-dimensionally bent copper coil 2 to exchange heat with the dissipated heat, achieving a cooling effect.

[0031] Working principle: When using the device of the utility model, the slag discharge channel 1, the U-shaped side plate 3 and the end baffle 4 are fixed at the slag discharge location, the water inlet pipe 201 is connected to the external cooling water inlet pipeline, and the water outlet pipe 202 is connected to the external return water pipeline. The smelting slag of the smelting furnace passes through the slag discharge channel 1 when it is discharged, and the large opening prevents slag from hanging. The cooling water passes through the three-dimensionally bent copper coil 2 to exchange heat with the dissipated heat, which has a cooling effect, prevents the slag discharge channel 1 from deformation, avoids slag gushing when the slag outlet is blocked or burned, and protects the personal safety of employees.
