Ningxia carbon valley ‘s carbon additive mainly used in casting to incease the recarburization and steel making it heats quickly with good effect and steady carbon yield. Carbon Additive could be used to adjust the carbon content and oxygen content of the molten steel change it's steel and strength thus to enhance the nucleating ability of the molten steel and the inherent quality of the billet. 

.the nature of use:High quality carbon - adding agent is an indispensable auxiliary additive for the production of quality steel.
