Electroslag remelting furnace with uniform smelting function

Abstract

The invention discloses an electroslag remelting furnace with the uniform smelting function. The electroslag remelting furnace with the uniform smelting function comprises a crystallizer and a vertical supporting column located on one side of the crystallizer; the vertical supporting column is provided with a transverse arm in sliding fit with the vertical supporting column; the end, away from the vertical supporting column, of the transverse arm is located above the crystallizer and provided with a holder; an electrode extending into the crystallizer is clamped and fixed to the holder; the holder comprises two oppositely-arranged clamping pieces; a clamping cavity used for clamping the electrode is formed between the two clamping pieces; a distributor plate connected with a power supply device is arranged on the lateral wall of one side of the transverse arm; a connection cable is arranged between the distributor plate and each clamping piece; the electroslag remelting furnace with the uniform smelting function further comprises a transverse arm lifting mechanism used for controlling lifting of the transverse arm, a stand column rotation mechanism used for controlling the vertical supporting column to rotate, and an electrode centering mechanism used for centering and positioning of the crystallizer and the electrode; and photoelectric sensors used for detecting the position of the electrode are annularly and evenly arranged on the top face of the crystallizer.

Description

technical field [0001] The invention belongs to the technical field of electroslag remelting equipment, and in particular relates to an electroslag remelting furnace. Background technique [0002] Electroslag remelting is a method of smelting using the resistance heat generated when the current passes through the slag as a heat source. Its main purpose is to purify metals and obtain steel ingots with uniform and dense clean structure. Steel remelted by electroslag has high purity, low sulfur content, less non-metallic inclusions, smooth surface of steel ingot, clean, uniform and dense, uniform metallographic structure and chemical composition. [0003] Electroslag remelting furnaces are widely used, mainly in the steel industry, metallurgical industry, etc. Different slag materials can be used to refine various alloy structural steels, heat-resistant steels, bearing steels, forging die steels, high-temperature alloys, precision alloys, corrosion-resistant alloys, high-stre...

AI Technical Summary

Problems solved by technology

[0005] 1. The current in the electrode is uneven, resulting in uneven melting and ultimately affecting the quality of the ingot;

[0006] 2. The cross arm has the defects of unstable operation and poor positional accuracy during the up and down movement;

[0007] 3. The position accuracy between the electrode and the mold is not enough, resulting in arc failure and mold deformation
