Problems solved by technology

The existing ladle refining furnace is usually divided into a furnace body and a furnace cover. Electrodes are used to heat the molten steel in the furnace body. Due to the high power, the electrodes generally generate serious heat, which causes the temperature of the furnace cover to rise, thereby affecting construction safety.

Abstract

The embodiment of the invention discloses a ladle furnace. The furnace comprises a furnace body, a furnace cover and an electrode, the furnace cover comprises an upper cover body, a first water cooling device, a second water cooling device and a cover bottom plate, the cover bottom plate is integrally connected with the upper cover body, and a groove matched with the upper end of the furnace bodyis formed at the bottom of the cover bottom plate. An electrode hole is formed at the top surface of the upper cover body, the electrode hole vertically extends to penetrate through the cover bottom plate, the electrode extends into the furnace body through the electrode hole, the first water cooling device comprises a first channel, the first channel is arranged in the upper cover body and spirally arranged at the peripheral side of the electrode hole, the second water cooling device comprises a second channel, and the second channel is arranged in the cover bottom plate in an S shape. The ladle furnace disclosed by the embodiment of the invention has the advantage of good cooling effect.

Description

technical field [0001] The embodiments of the present application relate to metal smelting, and in particular to a ladle furnace. Background technique [0002] In the prior art, a ladle refining furnace refers to equipment that also has the function of heating and refining a steelmaking furnace. It is an important metallurgical equipment used to refine the molten steel melted in the primary smelting furnace, and can adjust the temperature of the molten steel, buffer the process, and meet the needs of continuous casting and rolling. Existing ladle refining furnaces are usually divided into a furnace body and a furnace cover. Electrodes are used in the furnace body to heat molten steel. Due to the high power, the electrodes generally generate severe heat, which causes the temperature of the furnace cover to rise, thereby affecting construction safety. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present application is to pr...
