Abstract

LA PRESENTE INVENTION SE RAPPORTE A UN ROULEAU COMPRENANT DU CARBURE CEMENTE ET DE LA FONTE, AINSI QU'A UN PROCEDE POUR SA FABRICATION. LE ROULEAU PEUT ETRE UTILISE POUR LE LAMINAGE A CHAUD OU A FROID. LE CORPS COMPREND UN OU PLUSIEURS ANNEAUX EN CARBURE CEMENTE QUI SONT COULES PAR METHODE DE COULEE CENTRIFUGE EN UN CORPS DE ROULEAU EN UN ALLIAGE DE FER. L'ALLIAGE COMPREND UNE FONTE ESSENTIELLEMENT GRAPHITIQUE QUI APRES LA COULEE CONTIENT DE L'AUSTENITE RESIDUELLE. CETTE AUSTENITE RESIDUELLE EST TRANSFORMEE LORS D'UNE OU PLUSIEURS ETAPES SUBSEQUENTES DE TRAITEMENT THERMIQUE, TOTALEMENT OU PARTIELLEMENT, EN BAINITE PRINCIPALEMENT AVEC AUGMENTATION DE VOLUME, AFIN DE REDUIRE OU D'ELIMINER TOTALEMENT LA DIFFERENCE DE RETRAIT ENTRE LA FONTE ET LE CARBURE CEMENTE PAR SUITE DU REFROIDISSEMENT APRES LA COULEE. LA PARTIE CENTRALE DU CORPS DU ROULEAU PEUT ALTERNATIVEMENT SE COMPOSER D'UN AUTRE ALLIAGETHE PRESENT INVENTION RELATES TO A ROLLER COMPRISING CEMENTED CARBIDE AND CAST IRON, AS WELL AS A PROCESS FOR ITS MANUFACTURE. THE ROLLER CAN BE USED FOR HOT OR COLD ROLLING. THE BODY INCLUDES ONE OR MORE CEMENTED CARBIDE RINGS THAT ARE CAST BY CENTRIFUGAL CASTING METHOD INTO A ROLL BODY IN AN IRON ALLOY. THE ALLOY INCLUDES AN ESSENTIALLY GRAPHIC CAST THAT AFTER CASTING CONTAINS RESIDUAL AUSTENITY. THIS RESIDUAL AUSTENITY IS TRANSFORMED IN ONE OR MORE SUBSEQUENT STEPS OF HEAT TREATMENT, TOTALLY OR PARTIALLY, IN A BATH MAINLY WITH INCREASE IN VOLUME, IN ORDER TO REDUCE OR TOTALLY ELIMINATE THE DIFFERENCE OF WITHDRAWAL BETWEEN THE FUNCTION COOLING AFTER CASTING. THE CENTRAL PART OF THE ROLLER BODY MAY ALTERNATIVELY CONSIST OF ANOTHER ALLOY
