Abstract

L'INVENTION CONCERNE LES LANCES AUXILIAIRES DESTINEES A L'ECHANTILLONNAGE ET A LA MESURE DE TEMPERATURE D'UN METAL FONDU EN COURS D'AFFINAGE. ELLE SE RAPPORTE A UN ENSEMBLE COMPRENANT UNE LANCE AUXILIAIRE 4 QUI EST SOLIDAIRE D'UN CYLINDRE INTERNE 7. UN CYLINDRE EXTERNE 6, POUVANT TOURNER PAR RAPPORT AU CYLINDRE INTERNE, PORTE LES CANALISATIONS D'ARRIVEE ET DE DEPART D'EAU DE REFROIDISSEMENT QUI CIRCULE DANS LA LANCE AUXILIAIRE. UN MECANISME 11 FAIT TOURNER LA LANCE ET LE CYLINDRE INTERNE PAR RAPPORT AU CYLINDRE EXTERNE QUI NE PEUT PAS TOURNER. APPLICATION AUX CORNUES D'AFFINAGE PAR SOUFFLAGE D'OXYGENE PAR LE HAUT.
