Abstract

Procedimiento de fabricación de aceros microaleados, enque se parte de un acero microaleado con los siguientes intervalos de composición química en % de peso: C 0,25 - 0,50; Mn 1,3 - 1,6; Si 0,3 - 0,7; V 0,09 - 0,12; Ti 0,012 - 0,020 y N 100 - 200 (ppm), el cual es calentado a la temperatura de forja por encima de los 1000º C, y se le forja, para a continuación enfriarlo a una velocidad de 4 - 10º C/s hasta la temperatura entre 500-570º C que se forma una microestructura de ferrita acicular. De aplicación en la industria del acero.Manufacturing process for microalloyed steels, starting from a microalloyed steel with the following ranges of chemical composition in% by weight: C 0.25 - 0.50; Mn 1.3-1.6; Si 0.3 - 0.7; V 0.09 - 0.12; Ti 0.012 - 0.020 and N 100 - 200 (ppm), which is heated to the forging temperature above 1000 ° C, and is forged, and then cooled at a speed of 4 - 10 ° C / s until the temperature between 500-570º C that forms an acicular ferrite microstructure. Applicable in the steel industry.
