Submerged arc furnace system with automatic electrode lifting function and control method of submerged arc furnace system

Abstract

The invention relates to a submerged arc furnace system with an automatic electrode lifting function and a control method of the submerged arc furnace system. An electrode lifting device can drive an electrode (400) to ascend and descend. The monitoring module and the electrode lifting device are both electrically connected with the control module, the monitoring module monitors the electrical parameters of the electrode (400), a first fitting model between the power consumption of the electrode (400) and the loss amount of the electrode (400) is stored in the memory and can run on the first processor, and the second processor is used for determining the actual power consumption of the electrode (400) according to the electrical parameters. The first processor is used for determining the model loss amount of the electrode (400) according to the actual power consumption and the first fitting model, and the control unit is used for controlling the electrode lifting device to drive the electrode (400) to descend according to the model loss amount. According to the scheme, the problems that in the prior art, due to the fact that the electrodes of the submerged arc furnace ascend and descend by mistake, the three electrodes are difficult to keep in the third-class state, and the stability of the three-phase electrodes is damaged can be solved.

Description

technical field [0001] The present application relates to the technical field of alloy production equipment, and in particular, to a submerged arc furnace system with automatic electrode lifting and lowering and a control method thereof. Background technique [0002] The submerged arc furnace is also called submerged arc furnace. When working, the electrode needs to be inserted into the material layer to a certain depth. The electrode is used as a carrier for converting electrical energy into heat energy. When smelting ferrosilicon in a submerged arc furnace, the lower end of the electrode in the submerged arc furnace is discharged to melt the raw materials. At present, three-phase electrodes are often used. With the progress of smelting, the lower end of the electrode will be lost, resulting in the shortening of the length under the insert layer, which will lead to the change of the conductivity of the molten pool, and the actual position of the three-phase electrode needs ...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to control the rise and fall of the electrodes according to the magnitude of the detection electrode current in the prior art, which causes the electrodes to rise and fall by mistake, so that the electrodes rise and fall without loss, which makes it difficult for the three electrodes to maintain the "third-class" state. Destroy the stability of the three-phase electrodes, and thus cannot ensure that the submerged arc furnace can always be in the best smelting state. Provide a submerged arc furnace system and its control method with automatic electrode lifting, which can solve the problem of the submerged arc furnace in the prior art. It is difficult for the three electrodes to maintain the "third-class" state due to the false lifting of the electrodes, which destroys the stability of the three-phase electrodes.
