Abstract

1391849 Vertical tube furnaces ELECTRONIC MEMORIES & MAGNETICS CORP 21 April 1972 [21 April 1971] 18676/72 Heading F4B A vertical tube furnace for sintering magnetic cores comrises a treatment tube 18 with an upper parts feeder 14 and a pressure gas regulator 34, an outer tube 20 disposed within a refractory lining 24 enclosing electric heating elements 22, and a bore 16 for treated cores leaving the tube at 30. Cooling gas is supplied through a pipe 38. The furnace is divided into heating zones 41-44 by baffles 48 each zone having a thermocouple 50. The treatment tube 18 is about “ inch wide and may be made of Pt, the heating elements may be SiC rods and the tube 20 may be made of Al 2 O 3 . Owing to the presence of the gas, the cores, which may be <SP>1</SP>/ 50 inch in diameter, fall at random down the 7 foot treatment tube 18, the gas rate being controlled so that the cores take about 3 sees. in said fall. The cores may be rapidly tested to enable speedy adjustment of the furnace conditions.
