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 cross arm is facing the crystallizer and is equipped with electrodes extending down into the crystallizer; 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 is usually wel...

Problems solved by technology

In the existing electroslag smelting operation, the centering of the crystallizer and the electrode is done manually, which not only is cumbersome to operate, but also introduces human errors, resulting in large centering deviations

During the smelting process, the centering adjustment of the electrode and the crystallizer is also done manually under the continuous observation of the operator, which not only affects the use of production equipment, but also seriously reduces the production efficiency. Extract the corresponding size data information of the electrode and the crystallizer center during the smelting process, so it is difficult to control the relevant data of the smelting process in real time, and after a deviation occurs, the operator only adjusts the alignment of the electrode and the mold based on experience, which will inevitably cause secondary accidents , so the adjustment effect cannot be achieved

Poor alignment between the electrode and the crystallizer causes the mold to be heated unevenly, resulting in deformation and failure of the mold

Greatly shorten the service life of the crystallizer
