Abstract
Improvements in rotary kilns of indirect heating, for the previous treatment of minerals, for their subsequent feeding of iron and steel industries, essentially characterized, by comprising a tubular rotary furnace (6), working in continuous process and indirect heating, which allows the reduction of pulverized ferrous minerals, under an adjustable speed and working the tube slightly inclined, using as a reducing medium, the gas of generators, turning the furnace, supported by rolling rings (3) and driven by a gear wheel (5); to comprise a heat-insulating zone (8), filled with thermal insulating material, protected by a steel sheet (10), which separates it from the mantle-chimney (7), from the enclosing heater of another thicker plate (9), whose interior constitutes the chamber (6) of the furnace; by comprising longitudinal fins (16), steel welded by its base, in radial direction, on the inner wall of the sheet (9), which constitute the removers of the material under treatment; to be understood, bases (11) made of carbon steel, for the support of the fastening tabs of the rolling hoops (3) and of the toothed wheel, motor (5), whose bases have cavities on their inside suitable, for housing the outer end of fins (12), steel, for fastening the sheet (9), thanks to the welds (15), on the outer face of the sheet, while the opposite end of the fins (12), are isolated in the socket of the bases (11), thanks to thick insulating sheets (14), mica, asbestos or other antipyretic material, while the internal face of the sheet (10), it comes consolidated by fins (13), fixed by welding, by comprising joists (17), welded by its base (18), to the rings (19), of steel and by its ends, to the rolling rings; by comprising, at both ends of the tubular furnace, the relevant couplings of the hot gas inlet house and discharge device and, respectively, of the gas evacuation house and loading device.
