Basic structure of submerged arc furnace


Submerged arc furnace is a complicated electro metallurgical machinery, which is composed of heating furnace itself, furnace transformer, high current electric conductor (short network), electrode system software, submerged arc furnace feeding system, refrigeration system, high and low voltage power distribution system software, supervision and automation technology, tapping and slag removal system software, smoke exhaust system ash removal and other system software.


The basic structure of submerged arc furnace is shown in Figure 1 below. The high-voltage line given by the power grid can be converted into low-voltage and high current through the special transformer for submerged arc furnace, and the current is sent to the electrode through the high-current electric conductor. According to the carbon electrode sent into the furnace, the resistor heat and pulse heat caused by the return waste around the electrode and the end of the electrode will convert the electromagnetic energy into thermal energy engineering, so as to generate a high-temperature reflection area in the furnace body and carry out the reduction reaction of metal oxide iron ore. Coke and other carbonaceous oxidants are usually used to continuously add coke and recovered metal oxide iron ore raw materials into the wechat friend furnace. The reduction reaction in the reflection area continues. The obtained liquid commodities are stored in the fusion, and the outlet is opened on time to release them. Aluminum alloy commodities are obtained after pouring and casting of metal materials, and the coal ash is water quenched or poured before use.
