Metal electroslag remelting smelting device

Abstract

The invention discloses a metal electroslag remelting smelting device. The metal electroslag remelting smelting device comprises an overall furnace body structure and a crystallizing device which is installed on a plane below a step, and also comprises a stand column which is vertically installed on a plane above an installation step at one side of the crystallizing device, wherein a transverse cantilever is arranged above the stand column, an electrode bar which extends downwards to enter the crystallizing device is installed right opposite to the crystallizing device and adjacent to the an electrode bar chuck on the transverse cantilever, and the metal electroslag remelting smelting device is characterized by also comprising an atmosphere protection device, wherein the atmosphere protection device comprises a protection part structure and a transmission part structure, the protection part structure is provided with a protector, the protector is arranged in the furnace body and sleeves an annular hollow structure outside the electrode bar in a spacing manner, air outlets are uniformly distributed in the protector along the circumferential direction, the protector is connected with an inert gas source through a gas pipe, and the transmission part structure is used for controlling the protector to rise along with the rising of the liquid surface. By adopting the metal electroslag remelting smelting device, the follow-up atmosphere protection along with the rising of the liquid surface can be realized. The metal electroslag remelting smelting device has advantages of simplicity in structure, stability and reliability in operation and good atmosphere protection effect and good smelting effect.

Description

technical field [0001] The invention relates to a metal smelting technology, in particular to a metal electroslag remelting smelting device. Background technique [0002] Metal electroslag furnace (also known as electroslag remelting furnace) is a kind of metallurgical equipment that uses the resistance heat generated when current passes through slag as a heat source for smelting. Its structure mainly includes a furnace-like crystallizer as a whole, located on one side of the A vertical column is provided above the column, and a transverse cantilever is arranged on the horizontal cantilever, and an electrode rod extending downward into the crystallizer is installed on the horizontal cantilever against the crystallizer by the electrode rod chuck. [0003] When the electroslag furnace is smelting, the electroslag is put into the crystallizer, and a slag pool to be melted is formed above the crystallizer. The electrode rod chuck is used to clamp the cylindrical electrode rod, a...

Problems solved by technology

However, during the smelting process of the electroslag furnace, the metal liquid level will have a process of rising as the electrode rod descends, so the atmosphere protection device needs to be set at a position higher than the liquid level in order to avoid interference with the rising liquid level. There is a large space between the gas jet and the molten metal, it is difficult to exhaust the air, and it is difficult to achieve a good protective effect
