OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION IN A ROTARY KILN
The Tunnel Kiln is a firing kiln that is constructed on-site and operates by transporting products on kiln cars through the furnace. It delivers labor and energy savings and can reduce the amounts
ce technology of iron making got developed. During that time sponge iron was developed in shallow hearths using charc. ore are known as direct reduction process. After the development
The tunnel kiln technology was developed by Hoganas in 1911. In production of sponge iron through the tunnel kiln technology, it is possible to use both magnetite and hematite ores,
