[0002] Generally, a ladle needs to be baked after it is newly built and before it is filled with molten steel. In order to speed up the baking of the ladle, a ladle cover needs to be installed above the ladle. In traditional industrial furnaces, the ladle cover is usually opened and closed by lifting with a crane, which is inconvenient to operate and has great safety hazards. In addition to lifting with a crane, there is also an electric control method. Although the electric method can be automatically controlled, due to the heavy weight of the ladle cover, the motor needs to bear a large load, and the equipment cost and maintenance cost are high.
