Abstract
1,205,478. Descaling ferrous metals. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT. Feb. 16, 1968 [Feb. 16, 1967; July 13, 1967], No. 7670/68. Heading C7E. Descaling of all types of ferrous metal, including highly alloyed steel, is effected by heating with a molten alkali metal hydroxide and then with molten sodium with melts preferably at 230‹ -700‹ C. The sodium melt preferably floats in the alkali metal hydroxide melt and is covered by an inert gas atmosphere and/or salt melt. As shown in Figure 1 the sodium is contained in a funnel 3 which dips into molten NaOH in container 2. Rolls 5 guide the strip or wire through the NaOH, then the sodium and again through the NaOH.
