Abstract: A cooling arrangement, especially but not exclusively suited for cooling rolled stock such as wires and bars, has two end members provided with axially aligned passages through which a workpiece can travel. The end members are connected by an annularly arranged series of bars between which spaces are left free so that cooling fluid admitted into contact with the workpiece can rapidly flow off again. The space surrounded by the bars converges in the direction of travel of the workpiece. Upstream of one end member is provided a fluid admitting element formed with a workpiece guide passage which is divergent-convergent as considered in the travel direction of the workpiece.

Abstract: The disclosed process of continuously refining molten metal is carried out in a refining apparatus having communicating first and second refining stage spaces. Refining gas, such as oxygen, is blown into the molten metal in the presence of a slag layer on the molten metal. The molten metal and the slag are conveyed as two separate non-intermingled streams through the refining stage spaces, as distinguished from a slag-metal emulsion. The slag in the second refining stage space is caused continuously to flow back into the first refining stage space to form a slag layer on the molten metal in the first refining stage space. Refining gas is blown into the molten metal in the first refining stage space below said slag layer, and the molten metal is conveyed from said first refining stage space to said second refining stage space while preventing the flow of slag from said first refining stage space to said second refining stage space.

Abstract: Alloy steel sheeting for electrical purposes such as the cores of transformers, is made with isotropic magnetic properties by a method in which steel containing, by weight, up to 0.1% carbon, from 0.15 to 0.35% manganese, from 0.3 to 2.4% aluminium up to 0.25% copper, up to 0.5% sulphur, up to 0.2% phosphorus, up to 2.0% silicon and the balance iron except for impurities is hot rolled at a temperature of from 820.degree. to 1080.degree.C to cause at least 5% of it to have a crystal orientation {100} <hkl>. After this the sheet is cold-rolled with a reduction in cross-section of from 50% to 85% and then it is recrystallization-annealed at a temperature of from 820.degree. to 1200.degree.C. Preferably the cold-rolling is carried out in two stages and the sheet is annealed for from 10 to 30 minutes at a temperature of from 550.degree. to 950.degree.C between the two stages.
