Background

Currently, the transfer equipment used to transfer molten iron from a blast furnace to a converter is a ladle. The smelting of iron ore into liquid molten iron requires a lot of energy, but the distance between a blast furnace and a converter in a steel plant is often far and is not in a factory, so that when the molten iron is conveyed to the converter from the blast furnace by using an open type ladle, heat exchange between the molten iron and air is inevitably caused, thereby reducing the temperature of molten iron entering the furnace and finally increasing the steelmaking cost. In addition, a large amount of smoke dust emitted in the molten iron transportation process can pollute the environment, and the service life of related equipment is influenced.

Therefore, the ladle capping technology is implemented, the problems of heat dissipation and dust emission of the ladle during transportation can be obviously reduced, the field operation environment is improved, and the energy consumption and the consumption of auxiliary materials such as covering agents, carbonized rice hulls and the like are saved. The existing ladle capping technology adopts hydraulic pressure as power to realize the action of opening and closing the cap, but because the working environment of the ladle car is bad, the uncontrollable problems of low transmission efficiency, easy occurrence of sealing element damage, oil leakage and the like occur in the hydraulic transmission, and the working efficiency is reduced.
