Bell-type furnace for high-temperature annealing magnetic steel

摘要

Bell-type furnace for high temperature annealing oriented magnetic steel.; The invention relates to metallurgy and can be used for hydrogen-vacuum bell furnaces used in particular when high-temperature annealing oriented magnetic steel. Target Utility Model eliminate defectiveness of turns in the lower end of the roll. For this purpose, said furnace comprising nafevatelny hood 2 lined stand 1, nafevateli 3 and refractory support disc 5 provided with radial slots 6, where 10 is provided with a sheet roll is mounted steel additional supporting element in the form of two coaxially arranged annular discs 7 and 9, of which one 7 is made of carbon steel with thickness 25 + 40 mm and mounted on a turntable used superalloy and the other 9 made of magnetic steel, wherein between said discs disposed antifriction layer 8, the drive of the magnetic steel is arranged to cooperate with a roll 10; a sliding layer formed as a ground talcum not less than 1 mm thick. 1 z.p.f. 3 Fig.; abstract
