The output of the furnace is small, and the current of the one-phase or two-phase electrode decreases very little or does not decrease when the furnace is discharged, but rises instead.
The main measures to be taken to deal with the high consumption of electrode paste in a closed calcium carbide furnace are as follows:
Standard electrode pastes are mainly used in open-type submerged electric furnaces. One type of electrode paste is used in small and medium-sized ferroalloy furnaces and calcium carbide furnaces with open furnace surfaces.
In the smelting process, with the consumption and lowering of the electrodes, it is necessary to continuously add electrode paste and continuously extend the electrode barrel from the upper part.
One principle use Submerged arc furnace is also called electric arc furnace or resistance electric furnace. It is mainly used to reduce raw materials such as smelting ores, carbonaceous reducing agents and solvents. It mainly produces ferrosilicon, ferromanganese, ferrochromium, tungsten, silicomanganese and other ferroalloys, which are important industrial raw materials in the metallurgical industry and …
The electrode paste has problems during use, most of which are the overlapping effects of multiple factors. Among them, there is no shortage of U-turn phenomena.
Analysis on the Reasons of Under-burning of Electrode Paste in Submerged Arc Furnace Smelting Nickel Pig Iron
The working temperature of the ferronickel furnace is relatively low, so it is necessary to use the high-standard sealed electrode paste which is easy to roast and produced by Gongyi Rongxing Carbon. Rongxing Carbon can make the furnace stable and less accidents.The consumption of electrode paste is about 10kg per ton of iron, which can …
