Abstract
A metallurgical process involves providing an ingredient enclosure and placing a plurality of granules of a first material in the ingredient enclosure. The first material contains a first ingredient in a metallurgical process. A metallurgical process furnace having a chamber in which ingredients for the metallurgical process are added is provided and the ingredient enclosure and the first material are added to the chamber. The chamber is heated after the addition of the ingredient enclosure and the first material to the chamber, although it may also be heated prior to such addition. In one form, the granules comprise mill scale and the metallurgical process furnace is a blast furnace.
Claims25
A metallurgical process carried out in a furnace, the process comprising:
- providing a burden above the liquid iron in a furnace, the burden comprising sources of iron, carbon and flux;
- providing an ingredient enclosure that includes a venting system;
- placing a first material in the ingredient enclosure, wherein the first material comprises a first ingredient for carrying out a metallurgical process in the furnace and the enclosure includes a venting system;
- adding the ingredient enclosure and the first material to the burden;
- heating the burden after the ingredient enclosure and the first material have been added to the chamber thereby heating the first ingredient and causing a reaction gas to form within the enclosure;
- opening the venting system by opening a vent;
- expelling at least a portion of the formed gas via the enclosure venting system;
- opening the ingredient enclosure by the application of heat for a period of time;
- and
- exposing the first material to the liquid iron.
