    Abstract: A non-mechanical valve (3) for controlling the flow of fluidisable solids is disclosed. The valve (3) comprises a pipe having an upstream leg (5) with a solids inlet (13) at an upper end, a downstream leg (7) with a solids outlet (14) at an upper end, and a base section (9) interconnecting lower ends of the legs (5, 7). The valve (3) further comprises a means for introducing aeration gas into each of the legs (5, 7) to maintain fluidised flow of solids through the valve (3) and a means for adjusting the flow of aeration gas to the legs (5, 7) to control the solids flow through the valve (3).

    Abstract: The invention relates to a method for protecting the refractory lining of a metallurgical reaction vessel containing a smelt consisting of metal and slag, the reacting agents for the smelt being fed to the metal bath through introducing means disposed below and above the bath surface, and the gases escaping from the smelt being afterburned with oxidizing agents in the gas space, i.e. in the space above the still smelt, whereby gaseous reacting agents and/or gases acting inertly in the metal bath are fed to the smelt below the bath surface, and the total refractory lining surface in the gas space of the metallurgical reaction vessel is wetted by partial amounts of smelt in the form of drops, splashes, liquid portions rising or ejected eruptively and like a fountain and/or by wave or sloshing motion of the smelt.

    Abstract: A gas injection lance and an apparatus employing the lance for producing ferrous metal are provided. The lance has an elongated flow duct made of inner and outer concentric carbon steel tubes, a cooling water supply and return, and exterior surface which is designed to hold a frozen layer of slag on the duct, a gas inlet at a rear end of the duct, a tip joining the concentric tubes at the forward end of the duct, a non-metallic or refractory lining for the duct, and swirl-imparting member or members located in the duct for imparting swirl in the gas flow through the forward end of the duct.

    Abstract: An injection lance (26) for injecting hot gas into a vessel includes an elongate gas flow duct (31) which receives hot gas from a gas inlet structur e (32) and an elongate central tubular structure (33) which extends within gas flow duct (31) from its rear end to its forward end. Adjacent the forward en d of duct (31), central structure (33) carries a series of flow directing vane s (34) for imparting swirl to the hot gas flow exiting the duct. The wall of duct (31) downstream from gas inlet (32) is internally water cooled by flow of water through annular passages (43,44). The cooling water also flows through the interior of a duct tip (36) at the forward end of duct (31). The front e nd of central structure (33) which carries the swirl vanes (34) is internally water cooled by cooling water supplied forwardly through a central water flo w passage (52) from a water inlet (53) at the rear of the lance through to a nose (35) of the central structure. The cooling water returns back through t he central structure via an annular water return passage (54) to a water outlet (55) at the rear end of the lance.
