Covering and uncovering device of LF furnace

Abstract

The invention discloses a covering and uncovering device of an LF furnace. The covering and uncovering device of the LF furnace comprises an inverted-T-shaped fork tooth in the shape of an inverted T, a reversing device controlling the inverted-T-shaped fork tooth to swing, a fork tooth trolley installing the inverted-T-shaped fork tooth, a fixing frame and an electric-hydraulic pusher driving the fork tooth trolley to move along a running track, and the inverted-T-shaped fork tooth is formed by arranging a plurality of fork teeth forming a certain position front and back. The reversing device is arranged on the fixing frame through bolts. The inverted-T-shaped fork tooth is arranged under the reversing device, and the reversing device is parallel to the fork tooth trolley. The fork tooth trolley and the electric-hydraulic pusher are arranged on the fixing frame. The electric-hydraulic pusher is arranged over the fork tooth trolley. By means of stretching out or contracting back of the electric-hydraulic pusher, the fork tooth trolley is driven to move along the running track, the inverted-T-shaped fork tooth is driven to vertically swing along the angle of the reversing device, and the adjustment of the included angle between the fork tooth and the horizontal plane and covering / uncovering are achieved.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to an LF furnace cover removing device. Background technique [0002] Energy saving and emission reduction has become the overall strategic goal of the country. Iron and steel enterprises are large energy consumers. 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 by the crane, The operability of this technology in practical application is greatly restricted, so that this technology is mostly limited to the stage of continuous casting and pouring steel, and it is impossible to cover the ladle during the entire cycle of the ladle. Insulation on the ladle will cause the temperature loss of the molten iron in the ladle and the empty ladle during the entire recycling process, resulting in energy loss; at the same time, the empty ladle...

AI Technical Summary

Problems solved by technology

[0004] The present invention mainly solves the problem of "radiant heat dissipated to the air through the top opening of the ladle". Through the present invention, the ladle cover is always covered on the ladle except during the process of molten steel being discharged from the furnace, and the rest of the online recycling process, so that the top of the ladle is open. The radiative heat dissipation to the air is significantly reduced; moreover, in the service cycle of the ladle, both the capping and uncapping of the ladle cover are automatically completed through the ingenious mechanical structure design, neither overhead crane nor labor is required Intervention, bringing huge energy-saving benefits to iron and steel enterprises
