Fake electrode interconnecting device

Abstract

The invention discloses a fake electrode interconnecting device. The fake electrode interconnecting device is characterized by comprising a fake electrode sleeve arranged vertically; the lower end portion of the fake electrode sleeve is in a conical shape with the small-diameter end facing upward and used for positioning in cooperation with a frustum shape arranged on the upper end portion of a smelting electrode casting mould; the upper end portion of the fake electrode sleeve is in a vertical-cylindrical shape with the diameter larger than the largest outer diameter of a fake electrode and a positioning sleeve which is vertically arranged is arranged in an inner cavity of the fake electrode sleeve in a matched mode; and the inner surface of the positioning sleeve is in a frustum shape with the smaller-diameter end facing downward and used for positioning in cooperation with a frustum-shaped positioning section on the fake electrode. The fake electrode interconnecting device further comprises an inserting control mechanism which is arranged on the fake electrode sleeve and used for driving the fake electrode to be inserted into the smelting electrode casting mould by controlling the positioning sleeve. The fake electrode interconnecting device has the advantages of being simple in structure, convenient to operate, good in safety, high in production efficiency, good in quality of the prepared electrode and the like.

Description

technical field [0001] The invention relates to a metal smelting technology, in particular to a dummy electrode docking device. Background technique [0002] Metal electroslag furnace (also known as remelting electrode production device) is a kind of metallurgical equipment that uses the resistance heat generated when the current passes through the slag as the heat source for smelting. The column on the side is provided with a horizontal cantilever above the column, and an electrode rod extending downward into the crystallizer is installed on the lateral cantilever against the crystallizer by the electrode rod chuck. The electrode rod includes a dummy electrode at the upper end and a smelting electrode at the lower end. The smelting electrode is made of the refined material itself, which is gradually melted and consumed during the smelting process and flows into the crystallizer to form a steel ingot, so it is also called a consumable electrode. . [0003] The conventional...

AI Technical Summary

Problems solved by technology

In the inventive method, the consumable electrode and the dummy electrode are welded together by mutual fusion, the joint surface is large, the welding is firm and tight, and there is no looseness, and there is no problem of poor contact; but the mutual fusion welding process is manually operated, which still has labor intensity Large size, low safety, low efficiency, poor centering effect lead to low coaxiality of the prepared electrode and other defects, which affect the safety and quality of subsequent smelting
