Patent GB-1110071-A (GB)
Title: Improved method for the manufacture of tin plate
IPC: B21B3/02
Filed: 1965-10-06
Abstract: In a method of making tinplate, steel strip is tinplated, hot brightened in a furnace, coated with <PICT:1110071/C6-C7/1> a film of oil which is applied in an amount between 1.0 and 5.0 grams per base box, and cold reduced to the desired gauge, an aqueous chromate containing solution being applied to the oiled surfaces during the cold reduction.  The oil, which may be cottonseed oil or palm oil is applied in an electrostatic or emulsion type oiler and serves to lubricate the strips during cold reduction.  The cold reduction takes place in a mill 11 comprising two four-high stands 12A, 12B and tensioning devices 14A, 14B.  After passing the first roller stand 12A the oil thickness is reduced to 0.5 to 2 grams per base box which is insufficient to interfere with the action of a 1% to 2% solution of chromic acid sprayed from spray pipes, 15A, 15B.  The chromic acid solution is pumped from a tank 16 which may contain a heater 18 and serves both to cool the strip and to impart a film containing 0.5 to 0.6 milligrams per square foot of chromium to the tinplate.  After passing the sprays the strip passes through a hot air drier 19. Specific examples of tinplate production are given and a graph Fig. 3 (not shown) indicates the rolling force required for various thicknesses of oil film.

The coating may be formed in a series of plating steps with intervening baths of H 2 SO 4  of increasing concentration, the first bath containing 0.1 to 2% of the acid. The plated strip or sheet may then be coated with a lacquer or paint, or with a vegetable oil, or treated with chromic acid or alkali chromate.

A plurality of conduits 18 of helical form extend between upper and lower manifolds 20, 21 and are interwoven by metal screens 22 and the gas passages 31, 33 are formed by initially coating the conduits and screens with a readily vaporizable plastic composition e.g., polymethylmethacrylate dissolved in acetone, and subsequently volatilizing the coating leaving said passages. Duct 24 is charged with flame arresting layer of steel wool covered by a layer of nickel shot, and an additional flame arrestor 28 is located at the outlet of a duct 31. During charging of the vessel 10 with gaseous acetylene fed through ducts 31, 30, 24 liquid ethylene is forced from a container 42 through a valved duct 46 into the lower manifold 21 and from thence through the heat transfer conduits 18 thereby condensing the feed acetylene. The resulting ethylene vapour is discharged from the upper manifold 20 through a valved duct 50 and a heat transfer passage 58 of a refrigerated chamber 54 and the so condensed ethylene is returned to the container 42. To effect discharge of the vessel 10 which is assumed to have been disconnected from the ethylene circuit and transported to the consumer site liquid ethylene is withdrawn from conduits 18 through a duct 62 leading to an ambient air heated coil 66 connected by an ethylene vapour duct 68 to the upper manifold 20 thus completing a closed circuit and thereby vaporizing the solid or liquid acetylene for discharge as gas through ducts 24, 30, 31. The vessel 10 is insulated by powder 14 in an atmosphere of dry nitrogen or argon under pressure or vacuum. Instead of silica lime the filler material may be aluminium trihydrate, calcium carbonate, activated carbon solid carbon dioxide or ice.
