The process is mainly to carry out continuous burry arc slag-free smelting in a ferrosilicon furnace. During the whole smelting process, the carbonaceous reducing agent (blue carbon, metallurgical coke, etc.), the iron-containing material and the silica are formed into a furnace material according to a certain ratio, and the furnace is in the furnace. The electrode is deeply and stably inserted into the charge, and the ferrosilicon is obtained by an arc heating chemical reaction.
Submerged arc furnace adopts high-temperature combustion technology, which can fully utilize the thermal energy of coal during the production process, thereby improving energy utilization efficiency and saving energy consumption.
High production efficiency: The submerged arc furnace adopts an automated control system, which can achieve intelligent control, and the submerged arc furnace process of production is highly automated, improving production efficiency.
Environmental protection and energy conservation: Due to the use of high-temperature closed furnace technology in the submerged arc furnace by submerged arc furnace suppliers, it can effectively reduce smoke and dust emissions and carbon dioxide emissions. At the same time, it can also recycle waste gas during the production process, achieving the goal of environmental protection and energy conservation.
