Price:Available on request|Sulfur:0.8%|Size:10-30 mm, 20-40 mm, 30-80 mm|Key Properties: High Carbon Content: Metallurgical coke is primarily carbon, making it a strong reducing agent and fuel source. Hardness and Porosity: It's known for its strength and ability to support the weight of iron ore in blast furnaces, while also providing a porous structure for gas flow. Low Ash and Sulfur: Coke with low ash and sulfur content is preferred, as these impurities can negatively affect the smelting process and the quality of the final metal.:
Description
Metallurgical Coke is a carbon with high mechanical resistance produced from bituminous coal with special coking properties. It is heated in furnaces at 500°C to 1000°C in an oxygen-free atmosphere to fuse the fixed carbon with the inherent ash and expel most of the volatile matter. The end product is a solid, stable, and nearly pure non-fusible source of carbon.
About 90% of the metallurgical coke produced is used in the production of pig iron in the blast furnace where it has 3 main functions:
Fuel: Provides heat for the endothermic requirements of chemical reactions and the fusion of slag and metal.
Chemical reducer: Produces gases for the reduction of iron oxides.
Permeable support: Acts as the only solid material in the furnace that supports the iron load and provides a permeable matrix for slag and molten metal to pass into the crucible and hot gases make their way to the chimney.
