Metal wire feeding device, charging system and charging method

Abstract

The invention discloses a metal wire feeding device, a charging system and a charging method, and belongs to the technical field of electroslag metallurgy. The metal wire feeding device comprises a feeding channel, a pressing mechanism, a driving mechanism, a driving wheel and a support; the pressing mechanism comprises a guide rod, an elastic piece, a pressing wheel and a sliding sleeve; the guide rod is vertically arranged on the support; the sliding sleeve is arranged outside the guide rod in a sliding mode and connected with the guide rod through the elastic piece, and the pressing wheel is rotationally connected with the sliding sleeve; the driving mechanism is arranged on the support, is connected with the driving wheel and is used for driving the driving wheel to rotate; the driving wheel and the pressing wheel are arranged on the two opposite side portions of the feeding channel respectively, and the rotating plane of the driving wheel and the rotating plane of the pressing wheel and the feeding channel are located in the same plane; and the driving wheel and the pressing wheel can be connected with a metal wire material in the feeding channel in a rolling manner. By means of the metal wire feeding device, stable pressing conveying can be achieved, the conveying amount of metal wire materials can be accurately controlled, the oxygen content of an electroslag remelting system is stably controlled to range from 20 ppm to 30 ppm, and the quality of electroslag ingots is improved.

Description

technical field [0001] The invention belongs to the technical field of electroslag metallurgy, and more specifically relates to a metal wire material feeding device, a feeding system and a feeding method. Background technique [0002] Electroslag remelting is a process of re-refining steel (usually electric furnace steel, converter steel) made by general smelting methods. During the remelting process, active elements in steel such as Al, Ti, Ce, B, etc. are often lost due to oxidation. How to prevent the oxidation of active elements is one of the important metallurgical problems in electroslag remelting. During the electroslag remelting process, oxygen usually enters the slag and molten steel through the following channels: (1) oxygen dissolved in the original electrode steel and unstable oxides in the steel decompose at high temperature to release oxygen; (2) oxidation belt on the electrode surface Oxygen in slag; (3) Unstable oxides FeO, MnO, SiO in slag 2 、Cr 2 o 3 (...
