APPARATUS FOR INTRODUCING OF WIRE INTO LIQUID METAL Russian patent published in 2004 - IPC

FIELD: ferrous metallurgy, in particular, equipment for ladle deoxidizing and alloying of liquid metal.

SUBSTANCE: apparatus has support for wire roll, electric engine with chain drive, reducer with gears, feeder with guiding pipe, three pairs of upper and lower rollers arranged in succession inside feeder casing, with last terminating upper roller serving as measuring roller, and pneumatic cylinder fixed on feeder casing and connected with rollers through levers. Feeder has gear system, with gears being kinematically connected with one another, at least one additional pair of rollers, another row of pairs of rollers arranged in parallel with above three pairs of rollers and having terminating measuring roller, and additional guiding pipe for passage of wire over additional row of rollers from wire roll. Two pairs of first mentioned pairs of rollers and two pairs of each subsequent upper rollers in each row are connected through levers. All lower rollers are rigidly connected through pins with reducer gears, said reducer being arranged on casing so that roller and gear axes are axially aligned with one another. Three lower rollers are kinematically connected with three upper rollers for transmitting torque thereon. Electric engine is connected through chain drive to reducer gears and is arranged in feeder or outside it.

EFFECT: enhanced reliability in operation, increased precision in dosing of alloying wire, reduced noise effect and reduced impact loading of constructive members.
