Abstract

743,233. Gauges. ACIERIES ET FORGES DE FIRMINY. Aug. 31, 1953 [Sept. 16, 1952], No. 23995/53. Class 106 (2). [Also in Group XXII] In a pass adjusting device for a rolling mill a pair of measuring members is adapted to detect a preset distance between the rolls at each end and controls automatic means for maintaining the distance constant. In an example in which the roll pass is adjusted by hydraulic rams 65, Fig. 6, controlled from a hydraulic accumulator 64, each measuring member comprises a pneumatic nozzle 22 which detects a preset distance between cylindrical extensions 7, 8 of the rolls by pressure changes resulting from a variation in the outlet orifice section. A given value of pressure balances a diaphragm manometer 54 against the pressure behind a preset needle valve orifice 52. An electric contact 55 on the manometer controls a solenoid valve 59 connecting the hydraulic accumulator 64 to a supply 60 or exhaust 66. The mounting for the pneumatic nozzle 22, Fig. 4, comprises a slide 21 adjustable on a frame 15 having projecting feet 17, 19, 20 engaging the cylindrical extensions 7, 8 and held in position by an adjustably loaded spring 33. The slide 21 has feet 30 which are yieldingly held in engagement with V-grooves 28 on the frame 15 by a spring 23. The slide 21 at each end of the rolls is adjustable in position by a worm spindle 24 rotated through bevel gears 25, 26, shaft 46 and one of a pair of hand wheels 36, 42 which permit separate adjustment of the ends until the rolls are parallel and are then locked together for regulating the pass. Specification 629,623, [Group XXII], is referred to.
