Improved covering and uncovering device and method for steel ladle whole process covering

Abstract

The invention discloses an improved covering and uncovering device and method for steel ladle whole process covering. The device comprises four positioning columns welded to the upper part of the outer wall of a steel ladle, rotating shafts of the outer ends of the positioning columns rotationally support a guide seat through supporting rods, the rotating shafts are fixedly connected with an output shaft of a first rotating motor through couplings, the upper portion of the guide seat protrudes out to form a driving seat, a semicircular steel ladle cover is horizontally and slidably connected into the guide seat, a rack is fixed to the middle portion of the upper side of the steel ladle cover, a driving gear is rotationally limited in an inner cavity of the driving seat, a gear of the driving seat is engaged with a rack, a second rotating motor is arranged on the outer side of the driving seat, an output shaft of the second rotating motor passes through the driving seat and is fixedly connected with a driving gear inside the driving seat, and the steel ladle cover can be driven by the second rotating motor to slide horizontally. By means of the improved covering and uncovering device and method, the structure design is reasonable; and in the overall covering and uncovering operation process, manual operation is not required, and the device does not fall down, so that the devicedoes not need to be temporarily removed, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of smelting equipment, in particular to an improved capping device and method for ladle capping in the whole process. Background technique [0002] The ladle is an essential vessel for receiving molten steel and smelting reactions in the steelmaking plant. The heating and heat preservation of the ladle is an effective measure to improve the quality and output of molten steel. The ladle radiates and dissipates heat to the outside through its upper opening very quickly. Studies have shown that the heat dissipation rate of the lining and the surface temperature of the lining are proportional to the fourth power of the ambient temperature difference in the empty state. Therefore, this radiative heat dissipation can be significantly reduced by adding a thermal insulation cover on the ladle. Adding a cover to the ladle can reduce the heat dissipation of the ladle, reduce the temperature drop of the molten steel,...

AI Technical Summary

Problems solved by technology

[0003] At present, the steel ladle insulation cover used in the whole process of the ladle in China is only provided with a hook on the slag dumping side. The slag is turned in the opposite direction, and the heat preservation cover needs to be removed temporarily with the help of a special device. Due to the need to add additional equipment and increase manual operations, if the equipment fails, it will also affect the subsequent production of steelmaking, which limits the scope of use.

There are also thermal insulation covers designed to be flipped in both directions, but the thermal insulation cover is only hung on the ladle. As the flip angle increases, the thermal insulation cover will naturally go down under the action of gravity. Large-scale excavation of the pit, the amount of civil engineering is large and directly affects the stability of the foundation of the turner
