Title: Continuous heat treatment process for heat-treatable steels
IPC: C21D1/18
Filed: 1972-05-12
Abstract: 1371292 Continuously heat treating steel rod BAU-STRAHLGEWEBE GmbH 12 May 1972 [14 May 1971] 22385/72 Headings C7A and C7N Alloyed or non-alloyed steel rod containing 0À3% to 0À6% C and having a ferrite-pearlite structure is rapidly heated over its cross-section at an average rate of at least 200‹C/sec to a temperature between Ac, and 1300‹C, followed by quenching after the first phase transformation occurs in the central region but before substantial homogenization of carbon occurs by diffusion, the quenching being such as to produce a martensite-free structure, particularly a bainitic or troostitic one. In a particular embodiment the outer region of the rod is heated by electron beam or induction so that the centre is heated to not more than 1100‹C before quenching is effected; the latter may occur when the central and surface temperatures coincide. It is advantageous to preheat the steel to below Ac 1 , and particularly to below recrystallization temperature, by induction heating with deep penetration, and to quench with sprays.

Abstract: 1305243 Productions of nickel SHERRITT GORDON MINES Ltd 8 May 1970 [16 Oct 1969] 22435/70 Heading C7D In a process for the recovery of nickel from ammoniacal ammonium carbonate systems containing impurities including at least one of Zn, Mg and Mn in which the system is reacted with H 2  at elevated temperature and pressure, the SO 4 <SP>2-</SP> ion content of the system to be reacted with hydrogen is adjusted so as to provide at least the stoichiometric amount for the formation of soluble sulphates from the impurities prior to the reaction with H 2 . The SO 4 <SP>2-</SP> ion content may be adjusted by the addition of sulphates which do not provide cations which will precipitate with the Ni e.g. (NH 4 ) 2 SO 4 , H 2 SO 4 , NisO 4 . Alternatively oxidizable sulphur values e.g. elemental S, H 2 S 4  (NH 4 ) 2  S, Na 2 S, NiS may be provided in the system and the system reacted at elevated temperature, with a free-oxygen beaming gas, suitably between 65‹C. and 260 degrees, and preferably under pressure suitably above 5 psi oxygen partial pressure. This high temperature oxidation may also be carried out when the sulphate ion content is adjusted by adding a sulphate. Preferably, when the oxidation is carried out, the ammonia content of the system is adjusted to combine with any sulphate, in excess of the stoichiometrtc requirements, in the form of ammonium sulphate.

[Also in Group XIII] Gas-liquid contact apparatus for heat exchange comprises a tower 1 in which tubes 10, for the passage of a cooling-medium extend horizontally, the spaces between adjacent tubes in vertical alignment being bridged by slats 11 which are so arranged that the liquid, running down as a film over a tube, passes down as a film on each side of the slat and over the tube next beneath. The tubes 10 are in sets comprising tube plates 13 which are in communication with headers 15 which supply and take away the cooling medium. The opposed faces of the plates 13 are grooved at 12 to receive the ends of the slats 11, the lower edges of which are serrated at 11 and spaced slightly from the upper surfaces of the tubes 10, this being ensured by end feet 11b which rest upon the tubes. The upper edges of the slats are straight and are slightly spaced, i.e. “ inch or less, from the under sides of the pipes. Each set of tubes 10 is arranged at right angles to the set immediately above or beneath it. The invention is applicable to the contacting of corrosive gases and liquids such as hydrogen chloride gas and an aqueous solution thereof, in which case all contact surfaces are of non- metallic corrosion-resistant materials, such as carbon or graphite. The walls 2 of the tower are of carbon or graphite, or are of steel plate with a lining of carbon or graphite, or are made up of laminated plates of carbon or graphite which are machined flat, coated with synthetic resin and pressed together, the joints between adjacent plates being staggered. In the latter case the walls of the tower are strengthened by beams 17 extending between opposite tube plates 13, the beams being shaped to receive rods 18 with screwed ends which receive nuts 19. The tubes 10 and slats 11 are of carbon or graphite. The liquid is admitted through a pipe 3 to a distributing trough 8 from which it flows over a grid formed of rows of spaced thin carbon plates 9 having serrated lower edges, the plates in each row being at right angles to the plates in adjacent rows. The liquid is withdrawn at 4, whilst the gas enters at 5 and leaves at 6. Specification 679,131 is referred to.
