Abstract

The invention discloses an electroslag smelting method, which is characterized in that two sets of electrode devices are arranged beside a crystallizer, and then the two sets of electrode devices are smelted by using the crystallizer in turn, during the smelting process of one electrode device, the other electrode device The device performs the work of installing electrodes and preheating the electrodes. When the electrode device used for smelting is smelted and the electrodes are removed, re-feeding and the crystallizer are arranged, the preheated electrodes are moved into the crystallizer for smelting, and so on. Realize high-efficiency electroslag smelting. The invention has the advantages of high smelting efficiency, good safety, excellent smelting effect, safety, high efficiency and energy saving, and improves the smelting quality of electroslag steel ingots; at the same time, the bottom water tank is very convenient for maintenance and replacement, reduces maintenance costs, and improves cooling efficiency.

Description

technical field

[0001] The invention relates to an electroslag furnace smelting technology, in particular to an electroslag smelting method. Background technique

[0002] Electroslag smelting furnace is a kind of equipment for electroslag remelting. The structure of the electroslag smelting furnace mainly includes a furnace-shaped crystallizer as a whole, and an electrode device located on one side of the crystallizer. The lower end of the crystallizer is provided with a bottom water tank for cooling. The electrode device includes a pillar, and the movable sleeve on the pillar is equipped with a cross arm. , the cross arm is facing the crystallizer to install the electrode extending down into the crystallizer. The electrode includes the upper part for the fixed part connected with the cross arm and the lower part for the smelting part that is integrated into the electroslag during smelting; it also includes the smelting part for controlling The lifting mechanism that lifts ...

Examples

Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the best implementation mode and accompanying drawings.

[0040] The key point of this electroslag smelting method is that two sets of electrode devices are arranged next to a crystallizer, and then the two sets of electrode devices are smelted by the crystallizer in turn. During the smelting process of one electrode device, the other electrode device performs installation of electrodes and The work of preheating the electrode, when the electrode device used in smelting is finished and the electrode is removed, re-feeding and the crystallizer is arranged, the preheated electrode is moved into the crystallizer for smelting, and this cycle realizes high-efficiency electroslag smelting.

[0041] Specifically, in this embodiment, it is necessary to use such as Figure 1-3 The shown electroslag smelting electric furnace system is realized. The system includes a furnace-shaped crystallizer 1'...
