Abstract

226,801. Vacuumschmelze Ges., and Rohn, W. Dec. 24, 1923, [Convention date]. Hearths of metallurgical &c. furnaces are formed by filling in a dry granular refractory material, such as quartz sand, alumina, magnesite, or bauxite, beneath and behind a metal template or mould, which, when the furnace is put into operation, retains its shape long enough for the lining to frit and thereafter melts. When the normal working temperature is not sufficiently high to frit the refractory material, small quantities of other substances may be added, for example, glass powder, ground with oxide, ground slag, boracic acid, silicates, and borates. A suitable mixture for hearths sed in melting nickel-copper and nickel-copper-zinc alloys consists of quartz sand with 2 per cent powdered glass or 3 per cent boracic acid. A crack may be repaired by pouring in finelypowdered material and covering the crack with a strip of metal.
