[0002] A ladle is a container used in the steelmaking process. It is also known as a ladle furnace or converter. It is a large metal container used to hold and process steelmaking raw materials. In the steelmaking process, ladles are used to carry out operations such as converter steelmaking, top oxygen steelmaking or electric arc furnace steelmaking. Converter steelmaking is a common process in which the ladle is used as a huge container to heat the steelmaking raw materials to high temperatures and carry out smelting reactions to remove impurities and adjust the composition and temperature of the steel.

[0003] According to a vertical ladle baking machine disclosed in application number 202222780388.4, a combustion-supporting mechanism is provided to discharge the hot exhaust gas generated when the ladle is baked in the burner, and at the same time, combustion-supporting air is transported to the burner through a combustion-supporting fan, and the hot exhaust gas and the combustion-supporting air can exchange heat to avoid wasting hot gas.

[0004] However, the following problems still exist in actual use:

[0005] (1) The ladle roaster in the above-mentioned literature lacks a stirring mechanism, which causes uneven temperature distribution of the molten steel in the heating chamber of the ladle. This makes temperature control difficult during the smelting process. The temperature difference in different parts will lead to inconsistent smelting reaction rates, which in turn affects the quality and performance of the steel, and the heating efficiency will be reduced.

[0006] (2) The ladle roaster in the above-mentioned literature is troublesome to pour out the molten steel, which increases the complexity and time of the operation and the labor intensity of the operator, and easily leads to the inability to fully discharge the residual molten steel in the ladle, resulting in waste.
