Title (EN) POWDER FEEDING APPARATUS FOR CONTINUOUS CASTING
(FR) APPAREIL D"ALIMENTATION DE POUDRE POUR COULEE CONTINUE
Abstract:
(EN) Improvements in a powder feeding apparatus for continuous casting comprising a powder feeder (7) and a screw conveyor (11) carried by a truck (8) disposed in the vicinity of a casting mould, a guide rod (16) mounted on the screw conveyor (11), said guide rod being operatively associated with an arcuate guide (15) at the posterior portion of the screw conveyor (11), a crank mechanism (13) connected to the screw conveyor (11), a nozzle port (18) loosely fitted on the forward end of the screw conveyor (11) via the guide rod (16), and motors (12), (14) connected to the screw conveyor (11) and crank mechanism (13), respectively. This arrangement thus provides a powder feeding apparatus for continuous casting, wherein the nozzle port (18) can be adjustably reciprocated along the direction of the mold width. The optimum amount of powder can therefore be continuously charged uniformly spread over a molten steel surface during continuous casting.
(FR) Ameliorations apportees a un appareil d"alimentation en poudre pour coulee continue comprenant un dispositif d"alimentation de poudre (7) et un transporteur a vis (11) portes par un chariot (8) dispose pres d"un moule de fonderie, une tige de guidage (16) montee sur le transporteur a vis (11), ladite tige de guidage fonctionnant en association avec un guide en forme d"arc (15) situe sur la partie arriere du transporteur a vis 11), un mecanisme de volebrequin (13) rattache au transporteur a vis (11), une buse (18) montee libre sur l"extremite avant du transporteur a vis (11) par l"intermediaire de la tige de guidage (16), et des moteurs (12, 14) connectes au transporteur a vis (11) et au mecanisme de volebrequin (13), respectivement. Cette disposition de l"appareil d"alimentation de poudre pour coulee continue permet de regler la buse (18) dans le sens de la largeur du moule. La quantite optimum de poudre peut ainsi etre chargee uniformement etalee sur une surface d"acier fondu pendant la coulee continue.
