1287958 Measurement of temperature in converter vessels VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE AG 15 Dec 1969 [19 Dec 1968] 61054/69 Heading F4B [Also in Division G1] A device by means of which an elongated measuring instrument 11 may be supported in a metallurgical vessel having a shell 1 and a refractory lining composed of an inner lining 4, a rammed lining 3 and an outer lining 2, comcomprises a bushing 8 bolted to a ring 6 in the shell 1 and penetrating the outer lining and the rammed lining, the instrument 11 being carried by a sleeve 12 which is resiliently connected and sealed to the bushing 8 by a bellows-joint 20 which allows the instrument 11 to follow movements of the inner lining 4 relative to the other linings without imposing stress on the instrument. The instrument 11 which may be a housing for a thermocouple or a conductivity measuring rod is held in place in the sleeve 12 by a ramming mass 15 a seal 14 preventing escape of gases. The bellows-joint 20 is secured between a flange 13 on the sleeve 12 and a flange 16 on the bushing 8. The space 18 between the sleeve 12, bushing 8 and inner lining 4 is filled with grannular, refractory material e.g. magnesite powder which is not compressed on movements of the instrument 12. A seal 17 holds this material in place, and a further seal 10 is provided between the ring 6 and bushing 8. The instrument 11 is preferably water cooled. |
