Abstract:
A refractory, which is particularly suitable for use in an inner lining of a blast furnace, is obtainable by a process. The process includes providing a mixture containing coke, silicon and a binder. A green block is formed from the mixture. The green block is then baked. The baked block is semi-graphitized at a temperature between 1600 and 2000° C.
