Method for remelting and smelting metal electro slag

Abstract

The invention discloses a method for remelting and smelting metal electro slag. The electro slags are placed into a crystallizer, an electrode is inserted from an upper position, then the electrode is energized to enable the electrode, the electro slags and short net guide wires in the crystallizer to be switched on to form a current loop, and during the energizing, joule heat is discharged by the electrode and a slag pool, metal slag in the slag pool are molten, the molten metal is converged into a liquid state to flow through the slag pool to fall into the crystallizer to form a metal molten pool, and then the metal molten pool is solidified to form steel ingots; at the same time, during the smelting, auxiliary materials using aluminum particles as the main bodies are added, and the deoxygenation is carried out. The method is characterized in that during the smelting, the electrode is firstly inserted into the upper positions of the electro slags, the electro slags start to melt to fall into the crystallizer to form the metal molten pool, the electrode is controlled to slowly move downwards to be smelted, and the auxiliary materials are continuously and uniformly fed in a linkage control manner when the electrode move downwards. The method has the advantages of low cost, easy implement, automatic feeding of the auxiliary materials during smelting, stable and reliable feeding control process of the auxiliary materials, good smelting effect and the like.

Description

technical field [0001] The invention relates to a metal smelting technology, in particular to a metal electroslag remelting smelting method. 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 The column above the column is provided with a transverse cantilever, and the electrode clamp on the transverse cantilever faces the crystallizer and is installed with an electrode extending downward into the crystallizer. [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, and the electrode chuck is used to clamp the cylindrical electrode, and the electrode, the slag pool, the metal molten pool, ...
