The invention relates to a metallurgical furnace, comprising a furnace body (), a trunnion ring (), and a pedestal structure (). The furnace body () is arranged in the trunnion ring () rotatably about a rotation axis (A) by means of a supporting arrangement () comprising a bearing arrangement () between the trunnion ring () and the furnace body (). The supporting arrangement () comprises a first connection frame means () between the furnace body () and the bearing arrangement (), and a second connection frame means () between the bearing arrangement () and the trunnion ring (). The second connection frame means () is connected to the trunnion ring () by a first attachment () providing for movements between the second connection frame means () and the trunnion ring ().

Metallurgical furnace

A process for producing a solution of a gas in a liquid in which the gas is soluble, the solution having a predetermined concentration up to saturation. The gas and the liquid are brought together under controlled supply in a proportion corresponding to the predetermined concentration of the solution, and the gas and the liquid are caused to form a stream passing through a common conduit. The gas and the liquid in the stream are caused to intermix under the action of gravity, and the intermixing is repeated before the gas and the liquid have separated, so that the gas is substantially absorbed in the liquid, forming a gas-liquid solution of the predetermined concentration. The stream may be brought into turbulence for intensifying the intermixing of the gas and the liquid. An apparatus for performing the process includes a conduit including a continuous tubular coil formed with a plurality of upwardly and downwardly directed sections. Suitably, elements generating turbulence are disposed within the tubular coil, as is also a pressure-sustaining valve which maintains a predetermined overpressure in the conduit is provided. Suitably, the tubular coil is shaped as a horizontal helix.
