Product Overview
The Silico Manganese Furnace (Submerged Arc Furnace, SAF) is an industrial-grade electro-metallurgical equipment designed specifically for the production of Silico Manganese alloy (SiMn). Widely utilized by ferroalloy smelters and steel industry supply chain projects, this furnace operates on a three-phase AC power supply. By employing the submerged arc heating method within a closed furnace, it facilitates the carbothermic reduction of manganese ore, silica, and carbonaceous reductants to ensure the continuous and stable production of high-standard Silico Manganese alloys.
Working Principle
The Silico Manganese Furnace is a type of Submerged Arc Furnace (SAF). During the smelting process, graphite electrodes are inserted into the furnace charge (burden), with the electric arc completely covered by the material-a state known as 'submerged arc'. This process converts electrical energy into both resistance heat and reaction heat, allowing the burden to undergo reduction at high temperatures to form molten alloy. This technology is the industry standard for SiMn production due to its high thermal efficiency, stable furnace atmosphere, and minimal dust emission.
