Abstract: A method of starting a molten-bath based melting process includes establishing a sufficiently large and stable “hot zone” for ignition of oxygen and coal in a main chamber of a smelting vessel by independent means, i.e. independently of and before supplying cold oxygen and coal into the main chamber.
Abstract translation: 开始基于熔池的熔融工艺的方法包括：通过独立的方法，即独立于和供应冷氧和煤之前，建立一个足够大且稳定的“热区”，用于点燃熔炼炉主室中的氧气和煤 进入主室。

Abstract: A smelting apparatus that includes (a) a smelting vessel (4) that is adapted to contain a bath of molten metal and slag and (b) a smelt cyclone (2) for pre-treating a metalliferous feed material positioned above and communicating directly with the smelting vessel The apparatus also includes an oft-gas duct (9) extending from the smelt, cyclone for discharging an off-gas from the smelt cyclone. The off-gas duct has an inlet section (18) that extends upwardly from the smelt cyclone and is formed to cause off-gas to undergo a substantial change of direction as it flows through the inlet section of the off-gas duct.
