铁合金电炉生产过程中,电能的消耗在产品成本中占有很大的比重,75%硅铁电费占产品成本的57～60%。因此,除在工艺上、原料上考虑降低产品的电能消耗外,对设备上,尤其是电炉的导电设备应充分注意降低各部分的电能损失。我们曾对电炉的电气性能进行多次电气测定工作。经过验证分析,找出主要矛盾,把电炉设备进行针对性的改进,以降低电能损失。电能在电炉系统中的输送过程;由高压母线经过油开关到电炉变压器,经过电炉变
Ferroalloy EAF production process, the consumption of electricity in product cost account for a large proportion, 75% ferrosilicon electricity costs account for 57 to 60% of the cost. Therefore, in addition to the process, the raw material to consider reducing the power consumption of the product, the equipment, especially the electric furnace conductive equipment should pay adequate attention to reduce the power loss of each part. We have carried out several electrical measurements on the electrical properties of the furnace. After verification analysis, identify the main contradiction, the electric furnace equipment for targeted improvements to reduce power loss. Electricity in the furnace system of the transmission process; from the high voltage bus through the oil switch to the electric furnace transformer, after electric furnace change
