Abstract
La presente invencion se refiere a un método para producir acero para grandes moldes. De acuerdo con la invencion, este acero se obtiene mediante la fusionen un horno eléctrico seguido por una operacion metalurgica secundaria en una cuchara decalent amiento, siendo dicha operacion, seguida por un desgaseado bajoun vacio de menos de 1 torr, de hecho 0,2 torr, de una mezcla que tiene la siguiente composicion: manganeso, del 1 al 3%; silicio, < = 0,400%, fosforo,< = 0,015%, cromo de 1,5 a3,5%; mol ibdeno del0,25 al 1%; niobio, del 0,100 a 0,250%; de 100 a 300 ppm, de titanio o de circonio si fuese necesario; cobre,< = 0,300%; niquel, < = 0,300%; nitrogeno, < = 80ppm; oxígeno, <=80 ppm;calcio, <= 30ppm; de 15 a 50ppm de boro; de 0,10a 0,25% de carbono; azufre,< = 0,050%;aluminio < = 250ppm. También se propone el acero obtenido con dicho método.The present invention relates to a method for producing steel for large molds. According to the invention, this steel is obtained by fusing an electric furnace followed by a secondary metallurgical operation in a low-pressure spoon, said operation being followed by a degassing under a vacuum of less than 1 torr, in fact 0.2 torr , of a mixture having the following composition: manganese, from 1 to 3%; silicon, <= 0.400%, phosphorus, <= 0.015%, chromium from 1.5 to 3.5%; mol ibdeno from 0.25 to 1%; niobium, from 0.100 to 0.250%; 100 to 300 ppm, titanium or zirconium if necessary; copper, <= 0.300%; nickel, <= 0.300%; nitrogen, <= 80ppm; oxygen, <= 80 ppm; calcium, <= 30ppm; from 15 to 50ppm of boron; from 0.10 to 0.25% carbon; sulfur, <= 0.050%; aluminum <= 250ppm. The steel obtained with this method is also proposed.
