Abstract

The invention discloses a smelting control method of a metal electroslag remelting furnace. The method is characterized by comprising the following steps: before smelting, firstly installing three position sensors used for detecting the position of an electrode in the metal electroslag remelting furnace; secondly before smelting and during smelting, detecting the position of the electrode by the position sensors, feeding the position of the electrode, detected by the position sensors, back to a data control processing system and then controlling executive devices to move a crystallizer to achieve automatic centering of the electrode under closed-loop control, wherein the three position sensors are arranged in a concentric circle along the axial lead of the crystallizer and are uniformly distributed and fixed on the upper surface of the crystallizer in a ring shape. The method has the advantages that the method can conduce to facilitating centering, reducing the phenomenon of failure of the crystallizer and prolonging the service life of the crystallizer.

Description

technical field

[0001] The invention relates to the technical field of metal electroslag remelting and smelting; in particular, it relates to a metal electroslag remelting furnace. Background technique

[0002] Metal electroslag furnace is a kind of metallurgical equipment that uses the resistance heat generated when the current passes through the slag as a heat source for smelting. Its structure mainly includes a furnace-shaped crystallizer as a whole, and a pillar on one side of the crystallizer. The arm is facing the crystallizer, and the electrode extending downward into the crystallizer is installed on the cross arm; it also includes a data control processing system for electrical control.

[0003] Among them, the mold is the most critical part of electroslag remelting. The melting of electrodes, the refining of metals, the solidification and crystallization of molten metal, and the molding of ingots are all completed in the mold. The electroslag remelting crystallizer...
