LAM coke, or Low Ash Metallurgical Coke, is a solid carbon material used as a fuel in the iron and steel industry: 

• Production: LAM coke is made by the destructive distillation of low ash, low sulphur bituminous coal. 
• Uses: LAM coke is used in blast furnaces to produce pig iron, in cupola furnaces to produce cast iron, and in ferro alloy plants. It’s also used in foundries, and to increase the carbon content in steel manufacturing plants. 
• Other names: LAM coke is also known as “Met” coke. 

LAM coke has a low volatile content, but the ash constituents remain in the coke. Typical purities range from 82-92% fixed carbon. 

Low ash metallurgical coke is largely manufactured from imported low ash coking coal with ash < 9%. Low ash metallurgical coke is used as a fuel in the iron and steel industry. In foundries, coke is used in Cupola and in the iron and steel industry, it is used in blast furnace and ferro alloy plants.
