Double-smelting-position alternate vacuum self-consuming furnace

Abstract

The invention relates to the field of metal smelting equipment, in particular to a double-smelting-position alternate vacuum self-consuming furnace. The double-smelting-position alternate vacuum self-consuming furnace is provided with a lifting guide frame and a crystal oven. The lifting guide frame is provided with an electrode clamping device. A fake electrode is connected to the electrode clamping device in a clamping manner, and a self-consuming electrode is welded to the bottom of the fake electrode. A sealing cover is arranged between the crystal oven and the fake electrode. A transposition base capable of rotating in a reciprocating manner between two smelting positions is installed at the bottom of the lifting guide frame. A fixing frame is installed at the position, correspondingto the two smelting positions, below the electrode clamping device. The crystal oven is of a double-layer wall structure, and a water cooling device is arranged in the double-layer wall structure. Anelectroslag feeding port and an inert gas inflation opening stretching into the crystal oven are further formed in the oven wall of the crystal oven correspondingly. By means of the double-smelting-position alternate vacuum self-consuming furnace, the double-smelting-position alternate manner is adopted, uninterrupted continuous smelting with zero waiting time is achieved, and the smelting efficiency is greatly improved; and meanwhile a vacuum airtight crystallizer is adopted, the desulfurization effect in the smelting process is greatly improved, and the smelting quality is improved.

Description

technical field [0001] The invention relates to the field of metal smelting equipment, in particular to a dual melting position alternating vacuum consumable furnace. Background technique [0002] According to whether the electrodes are consumed during the smelting process, the electric arc furnace can be divided into non-consumable type and self-consumption type. Among them, the self-consumption type electric arc furnace is common in the industry, which is a kind of electroslag furnace. [0003] In terms of melting position layout, the common electroslag furnace has only one melting position, that is, after one smelting is completed, it is necessary to wait for the ingot solution in the crystallization furnace to flow out and cool down before proceeding to the next round of smelting. This process often requires several Hours, the smelting efficiency is extremely low, and it is often necessary to arrange multiple electroslag furnaces in industrial production, and staggered s...
