ESK Method For Sic Production

In 1973, the German ESK company improved the Acheson method and developed the ESK method. The large-scale SiC smelting furnace of Esk method is built outdoors, without end walls and side walls, linear or U-shaped electrodes are located at the bottom of the furnace, the furnace is up to 60m long, and sealed with polyethylene bags to recover the gas escaped from the furnace and extract sulfur It is then passed through the pipeline to generate electricity in a small thermal power plant. The furnace can use low-cost, high-activity, easy-to-react high-sulfur petroleum coke or coke as the raw material, and the sulfur content of the raw material is increased from 1.5% to 5.0%.
