The tundish baker directly heats the bottom of the tundish through the high-temperature flame generated by the burner, and realizes an efficient and energy-saving baking process through measures such as high-temperature flue gas recovery and reuse, turbulence formation and temperature uniformity. At the same time, the safety and reliability of the baking process are ensured through advanced control systems and monitoring equipment.

[0003] At present, the patent with the announcement number CN219900225U discloses an energy-saving tundish roaster, including a support platform, a dual-purpose burner is fixed at the bottom of the roaster body, a clamping mechanism is movably connected to the outer side of the roaster body, and a card slot is opened at the bottom of the roaster body. In the energy-saving tundish roaster, different rotating plates are clamped with sealing rings of different sizes, and the rotating plate can be rotated, which is convenient for flexible switching of different sealing rings. After the roaster body is moved to the top of the sealing ring to be used, the roaster body can be lowered, and then the rotating ring rotates, and the extrusion block squeezes the pin to move, and the pin passes through the card block, which is convenient for locking the roaster body and the sealing ring together. After that, the roaster body and the sealing ring can be positioned as a whole to the top of the tundish of the continuous casting machine, and the sealing ring can play a role in strengthening the seal, which can effectively reduce the heat loss.

[0023] The energy-saving tundish roaster in the utility model is similar to the existing tundish roaster in structure, such as the patent with announcement number CN219900225U which discloses an energy-saving tundish roaster. The main improvement of the utility model is that the temperature of the flame during combustion is controlled by adjusting the content of gas, air and oxygen in the mixing box 4, and the gas is burned more fully, so that the baking efficiency is higher, the use of gas is reduced, and resources are effectively saved. Figures 1 to 6 As shown, the tundish roaster with good energy-saving effect in the utility model is used to open or close the inlet 11 opened in the mixing box 4 according to needs. When only air is used as the combustion-supporting agent, the first regulating mechanism 8 is used to block the inlet 11 of the pure oxygen delivery chamber 5 with the first closing plug 806, so that pure oxygen cannot enter the mixing box 4. When oxygen-enriched combustion is used, the first regulating mechanism 8 is used to make the first closing plug 806 appropriately away from the inlet 11 on the inner wall of the pure oxygen delivery chamber 5, so that the inlet 11 on the inner wall of the pure oxygen delivery chamber 5 is partially opened, thereby delivering pure oxygen into the mixing box 4, increasing the oxygen concentration in the mixing box 4, and promoting the combustion of the fuel gas. , so that the gas burns more completely, the temperature of the burning flame can be increased, and resources can be saved. When only pure oxygen is used for flame retardancy, the second regulating mechanism 9 is used to close the second closing plug 906 away from the inlet 11 on the inner wall of the air delivery chamber 6.
