Abstract

970,859. Nozzles; feeding granular &c. material. BOT BRASSERT OXYGEN TECHNIK A.G. March 29, 1961 [April 14, 1960], No. 11589/61. Addition to 970,858. Heading F4B. [Also in Division C7] Apparatus for carrying out metallurgical processes (see Division C7) comprises a hearth, particularly an open hearth, furnace 3 and a cooled blowing device 4 extending through the roof 1 of the furnace and being guided to be vertically lifted and lowered, the blowing device comprising a water-cooled blowing tube 5 and a downcomer 6 similar in construction to that disclosed in the parent invention. Surrounding the blowing tube, a cooling cylinder 11 is located in the furnace roof.
