Método e aparelho para produção de ferro gusa por meio de fusão redutora e metodo de obtenção de uma instalação como essa

摘要

A plant for a smelting reduction process for pig iron production using coal and oxygen-containing gas is obtained by converting an existing blast furnace plant by replacing the blast furnace (1) by apparatus including at least one metallurgical vessel (8) for carrying out the smelting reduction process, while retaining at least partly at least one of the following components of the existing blast furnace plant: i) storage bins (4) for iron ore ii) storage bins (5) for coke, as storage bins for coal iii) a casting house (18), for tapping of the metallurgical vessel iv) a gas discharge system (23) for hot gas including dedusting means (24), v) a cooling water supply system (25).
