The Basic Structure of Submerged Arc Furnace
The submerged arc furnace is a kind of complicated electrical metallurgical machinery. It consists of the heating furnace itself, the transformer for the furnace, the high-current electrical conductor (short-circuit), the electrode system software, the submerged arc furnace charging system, the refrigeration system, and the high and low voltage power distribution system. Software, supervision and automation technology, tapping and slag removal system software, fume extraction system ash removal, and other system software.
The submerged arc furnace is an industrial electric furnace with huge power consumption. Mainly consists of a furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressing and lifting system, loading and unloading system, controller, burn-through device, hydraulic system, submerged arc furnace Transformers and various electrical equipment
The basic structure of the submerged arc furnace is shown in Figure 1 below. The high-voltage line provided by the power grid can be converted into low-voltage and high-current through the special transformer of the submerged arc furnace, and the current is sent to the electrode through the high-current electrical conductor.
According to the carbon electrode input into the furnace, resistance is caused by the returned waste around the electrode. The heat of the furnace and the pulse heat caused by the end of the electrode convert the electromagnetic energy into thermal energy and then generate a high-temperature reaction zone in the furnace body to carry out the reduction reaction of metal oxide iron ore.
Usually, carbon oxidants such as coke are used to continuously add coke and recovered metal oxide iron ore raw materials to the furnace, and the reduction reaction in the reflection area continues to develop, and the obtained liquid products are stored in the fusion furnace, and the furnace is opened on time.
It is released through the mouth, the metal material is poured, cast, and rolled to obtain aluminum alloy products, and the coal ash is water quenched or poured before use.
