Carbon Additive
Product characteristics: Electrocalcined coal is produced by selecting high-quality anthracite as raw material and calcining it in a single cross current electric calcination furnace at 2000 ℃. It can effectively remove moisture, volatile matter, improve density and conductivity, enhance mechanical strength and oxidation resistance during the production process. It has excellent characteristics of low ash, low sulfur, low phosphorus, high calorific value, and high compressive strength.
