Electro-hydraulic drive M-shaped steel ladle capping and decapping device

Abstract

The invention discloses an electro-hydraulic drive M-shaped steel ladle capping and decapping device, which relates to the structure of a whole-course full-automatic capping and decapping device of a high-temperature melt container in metal smelting. The electro-hydraulic drive M-type steel ladle capping and decapping device comprises a fixed frame, wherein the fixed frame is fixedly connected with an electro-hydraulic push rod and a connecting rod mechanism; the fixed frame is hinged to an M-shaped prong assembly; the electro-hydraulic push rod is connected with the connecting rod mechanism; the connecting rod mechanism is hinged to the M-shaped prong assembly. According to the electro-hydraulic drive M-type steel ladle capping and decapping device disclosed by the invention, the electro-hydraulic push rod is stretched to drive the connecting rod mechanism to control the swinging of the M-shaped prong assembly, an included angle between the M-shaped prong assembly and the horizontal plane is regulated, and capping and decapping are realized by the movement of a buggy ladle. High-cost heat energy is avoided and prevented from outwards losing to the outside from a steel ladle lining used for containing molten steel and liquid steel, the steel mill production cost is lowered, the operation condition is improved, and the production rate is improved.

Description

technical field [0001] The invention relates to the structure of a full-automatic capping and uncovering device for high-temperature melt containers in metal smelting. Background technique [0002] Energy saving and emission reduction has become the country's overall strategic goal, and iron and steel enterprises are big energy consumers. At present, the path of heat energy loss during the use of the ladle is generally composed of two parts, one is the conduction heat between the lining and the cladding, and the other is the radiant heat dissipated to the air through the opening at the top of the ladle. In order to solve the second part of the problem of "radiant heat dissipated to the air through the top opening of the ladle", some iron and steel enterprises have already started the ladle capping operation on the continuous casting machine. However, because the existing ladle capping operation must be completed with the assistance of the crane , so that the operability of ...

Problems solved by technology

In order to solve the second part of the problem of "radiant heat dissipated to the air through the top opening of the ladle", some iron and steel enterprises have already started the ladle capping operation on the continuous casting machine. However, because the existing ladle capping operation must be completed with the assistance of the crane , so that the operability of this technology in practical applications is greatly limited, so that most of this technology is only used in the stage of continuous casting and pouring steel, and it is impossible to keep the ladle covered during the entire cycle of the ladle. Covering the ladle for heat preservation will result in a serious loss of temperature during the entire recycling process of the molten iron in the ladle and when the ladle is empty, resulting in energy loss; at the same time, there will be no ladle during the entire recycling process when the empty ladle is filled with molten iron or just after pouring the molten iron If the cover is covered, the high temperature in the ladle will convect with the ambient temperature in the workshop of the iron and steel enterprise, causing the dust in the workshop to fly and pollute the environment, causing damage to the workers on the line; The effect of energy saving and environmental protection expected by workers, most of the heat lost from the refractory lining of the ladle and the molten steel in the ladle has not been effectively controlled
