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.

First claim

The invention claimed is:

1. A method of manufacturing a refractory, which comprises the steps of:
providing a mixture containing coke having an iron content of at most 0.1% by weight, silicon and a binder;
forming a green block from the mixture;
baking the green block at a temperature between 700 and 1200° C. and resulting in a baked block; and
semi-graphitizing the baked block at a temperature between 1600 and 2000° C.

2. The method according to clai…
