Coking Coal for steel production and alternatives . By Noah Beecher Kelk Metallurgical coal, also called metcoal or coking coal, is a type of coal that is used in the production of steel It is of a higher purity than thermal coal which is used in energy generation To make steel, metcoal is heated at around 1100
Coal is a key part of the cokemaking process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed. The cooked coal, called coke, is removed from the oven after 18 ...
