Coke is made from crushed coal baked at high temperatures (somewhere around 1000 C) for at least 18 hours to remove water, tar and coal gas. It comes out as hard and porous concentrated carbon.
Metallurgical Coke. Metallurgical Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace where a uniform and high temperature is required. It is widely used at integrated plants as well as secondary steel / Pig Iron (Mini Blast Furnaces), Foundries, and Zinc Copper Smelting.
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 LAMC include integrated steel plants, industry/foundries producing Ferro Alloys, Pig Iron, Engineering Goods, Chemicals, Soda Ash and Zinc units etc.
Metallurgical coal, also known as coking coal, is a low sulfur, low ash, and low phosphorus grade of coal. It is used to produce highgrade coke, which is an important reactant for manufacturing of primary steel in the blast furnace process.
Metallurgical coal is a grade of lowash, lowsulfur and lowphosphorus coal that can be used to produce high grade coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies will often have a ...

The weight percent of the + ⅜" coke equals the CSR. Most blast furnaces will require a coke with a CSR greater than 60 and CRI less than is committed to providing accurate, cost effective blast furnace coke analysis for your operation. SGS is the world leader in coal and coke analysis and testing.
Mar 29, 2019· How to Crush a Can with Air Pressure. You can crush a soda can using nothing more than a heat source and a bowl of water. This is a great visual demonstration of some simple scientific principles, including air pressure and the concept of...
If the metallurgical coke with a grain size of 2575 mm is used in the blast furnace, the coke ratio of blast furnace will be greatly reduced. Low. The whole method is to use the coke cutter to crush the coke pieces larger than 80mm. The mechanical strength of coke broken by coke cutter is obviously improved. Achieve full dry quenching.
Coal for metallurgical coke production: predictions of coke quality and future requirements for cokemaking Dı´ez*, R. Alvarez, C. Barriocanal Instituto Nacional del Carbo´n (INCAR), CSIC, Apartado 73, 33080 Oviedo, Spain Accepted 31 October 2001 Abstract
The Roles of Coal and Coke in Steelmaking. Metallurgical coke, or met coke, is manufactured from blends of bituminous coal in a heated distillation process resulting in a nonmelting carbon. Coke is made by one of two processes: byproduct or nonrecovery, also known as heat recovery . Coke Manufacturing .
Briquetting increases strength of coke produced and to make non coking or poorly coking coals to be used as metallurgical coke. Blending prevents damage to oven when high pressure develops. (b) Coke oven: Oven has usually to width. Here coal is kept for 17 hrs, heat is supplied completely from the flues on the sides.
