What is Coke
Coke is made by destructive distillation of a blend of selected Bituminous coals (called Coking coal or Metallurgical coal) in special high temperature ovens in the absence of oxygen until a large part of the volatile matter is driven off. The resulting product, COKE, consists principally of Carbon.
Traditionally, chemistry, size & strength (both cold as well as hot) have been considered the most important properties for use in the blast furnace. The quality of the constituent coals determines the characteristics of the resultant coke.
Coke is primarily used to smelt iron ore and other Iron bearing materials in blast furnaces, acting both as a source of heat and as a chemical reducing agent to produce pig iron or hot metal. Coke also serves as a structural material to support the deep bed of coke/iron oxide/limestone that makes up much of the furnace volume. It is in this last role that its properties are crucial. It is important that it does not degrade (e.g. break up into small particles) during its descent through the oxidizing hot gases passing through the stock region of the furnace.
Low Ash Metallurgical Coke is required for metallurgical and chemical industries and is used as the primary fuel where high temperature and uniform heating is required. The industrial consumers of Lam Coke include integrated steel plants, industry/foundries producing Ferro Alloys, Pig Iron, Engineering Goods, Chemicals, Soda Ash and Zinc units etc.
At Jindal Coke Limited, we manufacture Lam Coke of sizes, customized to meet the requirements of the clients with whom we maintain long term relationships. On broader form most of the blast furnaces uses the size with 25-80/90 mm Coke and smaller size of Coke 06-25, 10-30/40 mm is being used in ferro Alloys industry.
Metallurgical Coal is in our process used are the best coals available from Australia and US which results in to the best of quality coke.
