Abstract: The invention relates to a metallurgical furnace, comprising a furnace body (1), a trunnion ring (2), and a pedestal structure (3). The furnace body (1) is arranged in the trunnion ring (2) rotatably about a rotation axis (A) by means of a supporting arrangement (4) comprising a bearing arrangement (5) between the trunnion ring (2) and the furnace body (1). The supporting arrangement (4) comprises a first connection frame means (7) between the furnace body (1) and the bearing arrangement (5), and a second connection frame means (8) between the bearing arrangement (5) and the trunnion ring (2). The second connection frame means (8) is connected to the trunnion ring (2) by a first attachment (9) providing for movements between the second connection frame means (8) and the trunnion ring (2).

Abstract: 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.

Abstract: A metallurgical furnace unit (1) includes a cylindrical furnace body (2) which is intended for rotation and/or tilting or like movement and is provided with at least one ring (7) mounted outside the furnace body (2) and functioning to enable such movement to take place. Each ring (7) is spaced from the furnace body (2) and connected to said body by means of a force transferring supporting-member (6) that extends in the longitudinal direction of the furnace unit (1). The supporting member (6) is adapted to prevent the transfer of furnace body movements caused by thermal expansion to the ring (7), and to take-up external loads from the intrinsic weight of the furnace body and the weight of the furnace charge.
