Abstract
922,226. Annealing steel wires. LE FOUR INDUSTRIEL BELGE. June 26, 1959 [June 27, 1958], No. 22091/59. Classes 72 and 82. A process for the heat treatment of steel wires in which the wires are continuously passed into a furnace where the wire is heated by hot gases, first in an oxidizing atmosphere and then in a non-oxidizing atmosphere to a temperature of at least 700‹ C. comprises entraining the furnace gases transversely across the furnace at a minimum speed of three metres per second by means of gas burners, maintaining the zone in which the temperature is above 500‹ C. free from oxygen, and subjecting the hot wire to rapid cooling out of contact with oxygen. As shown, wires 5 enter the furnace through an inlet 2 and are heated by gases from burners 8. In the first part of the furnace, i.e. that shown in Fig. 1, the gases are oxidizing to burn off any soap or other lubricant on the wire, and in the second part, i.e. that shown in Fig. 2, the gases are non-oxidizing and the temperature of the wire may be raised to above 700‹ C. The burners adjacent the outlet 7 may be adjusted to give a carburizing atmosphere to give some case-hardening to the wire which is then passed out of contact with the air into a cooling bath 15 which may be of molten lead maintained at 500‹ C. by cooling air from a fan 25. The wire may be cooled by a transverse flow of furnace gases cooled to the desired temperature, Fig. 8 (not shown).
