The furnace shapes include pear-shaped, straight barrel-shaped, and drum-shaped. According to the chemical properties of the furnace lining, it can be divided into acid converters and alkaline converters; according to the position of the tuyere and oxygen supply pipe, it can be divided into bottom-blown converters, side-blown converters, and top-blown converters. For non-ferrous metal blowing, an acidic or alkaline side-blown drum converter is used to generate the required heat energy by oxidizing sulfur in the molten metal. It is mainly used for steelmaking in industry.
