DEVICE FOR PLUGGING OF METALLURGICAL VESSEL TAPHOLE Russian patent published in 2000 - IPC

Abstract RU 2144960 C1

FIELD: ferrous metallurgy, particularly, devices for cutoff of metal from slag and plugging of tapholes, for instance, converter in metal tapping. SUBSTANCE: device has turning lever carrying locking member with axial channel for supply of retaining medium and conical taphole on the side of its mouth; cylinder whose piston is connected with rack gear; pipelines for supply of medium to cylinder and pipeline for retaining medium. Device is provided with axle hinged relative to vessel, distributing unit with channels and pipeline for cooling medium. Distributing unit is installed on vessel between turning lever with locking member and rock gear. Axle is running through distributing unit and its one end is secured to gear of rack gear, and its other end is connected with turning lever. Turning lever and axle have axial channel, at least on section from distributing unit to lever. Axial channel is connected with distributing unit channels. Pipeline of cooling medium is connected with distributing unit channels, cylinder and rack gear. Locking member of device may be made of heat-resistant cast iron. EFFECT: higher reliability and prolonged service life of device, reduced expenditures for interheat repairs. 2 cl, 1 dwg
