Ladle capping device and ladle capping method

Abstract

The invention discloses a hot metal ladle capping device and a hot metal ladle capping method.The capping device comprises a hot metal ladle cover, an electromagnetic adsorption and lifting system and a support rotating system; the electromagnetic attraction and lifting system comprises an electromagnetic chuck, an electromagnetic chuck fixing ring, an electromagnetic chuck lifting noose, a first fixed pulley shaft, a first fixed pulley, a second fixed pulley shaft, a second fixed pulley, an electromagnetic chuck lifting winch, an electromagnetic chuck power line and an electromagnetic chuck control box. The support rotating system comprises a vertical support main shaft, a horizontal support cross arm and a support rotator. The method can obviously reduce the temperature reduction of the molten iron in the process of transporting the molten iron from the ironmaking process to the steelmaking process, provides a better temperature basis for converter production, can effectively reduce the outward heat radiation quantity of the empty ladle after the molten iron is poured, maintains the higher temperature in the empty ladle, provides a favorable basis for receiving the molten iron next time, and improves the production efficiency. Therefore, important contributions can be made to energy conservation and emission reduction of the whole steel smelting process.

Description

technical field [0001] The invention belongs to the technical field of ladle, in particular to a ladle capping device and a ladle capping method. Background technique [0002] In long-process iron and steel production enterprises, the blast furnace of the iron-making process and the converter of the steel-making process are generally far away, so the transfer of molten iron is usually realized by railway transportation or automobile transportation of ladle. Conventional ladle usually adopts open design to facilitate the acceptance and pouring of molten iron, but this open ladle has poor thermal insulation effect on molten iron, resulting in excessive temperature drop of molten iron in the ladle, resulting in more energy waste. It is not conducive to the energy saving and emission reduction of iron and steel enterprises. SUMMARY OF THE INVENTION [0003] In order to solve the technical problems existing in the above-mentioned prior art, the present invention provides a lad...
