Production normally takes place in a coke battery located near an integrated steel mill. In the battery, coke ovens are stacked in rows. Coal is loaded into the ovens and then heated in the absence of oxygen up to temperatures around 1,100 degrees Celsius (2,000 degrees Fahrenheit). Without oxygen, the coal does not burn; it begins to melt.
