Submerged Arc Furnace Transformer Cooling Device and Its Application Method

Abstract

The invention relates to the field of cooling devices and discloses a cooling device for a transformer of a submerged arc furnace and a utilization method of the cooling device. The cooling device comprises at least two water cooling devices. Each water cooling device comprises a water inlet, a water outlet, an oil inlet, an oil outlet and a heat exchanger, wherein the water inlet is connected with a water inlet pipe, the water outlet is connected with a water outlet pipe, the oil inlet is connected with an oil outlet pipe of the transformer, and the oil outlet is connected with an oil inlet of the transformer. The cooling device for the transformer of the submerged arc furnace and the utilization method of the cooling device have the advantages that by the at least two water cooling devices used serially, parallelly or singly, flexibility and cooling performance of the whole cooling device are improved, the problem of production halt caused by clearing of scales on the inner wall of the cooling device is avoided, and the problems of oil temperature rise and the like of the transformer due to the fact that the cooling device fails to meet the requirements when product yield is increased and material varieties and product varieties are changed are solved.

Description

technical field [0001] The invention relates to the field of cooling devices, in particular to a cooling device for submerged arc furnace transformers and an application method thereof. Background technique [0002] Submerged arc furnace is also called arc electric furnace or electric resistance electric furnace. It is mainly used for reducing smelting ores, carbonaceous reducing agents and solvents and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. The submerged arc furnace is an industrial electric furnace with huge power consumption. The submerged arc furnace transformer is the most important and critical power supply equipment for the submerged arc furnace. The reliable and safe operation of the transformer is directly related to the quality and o...
