Blended charge for steel production

A blended charge for use as a decarburizing addition to a steelmaking batch comprises 50 to 95% by weight of an iron-carbon alloy and 5 to 50% by weight oxide material. The oxide material includes free metal oxides in excess of 0.25% by weight having an affinity for oxygen less than or equal to carb...

Zusammenfassung:	A blended charge for use as a decarburizing addition to a steelmaking batch comprises 50 to 95% by weight of an iron-carbon alloy and 5 to 50% by weight oxide material. The oxide material includes free metal oxides in excess of 0.25% by weight having an affinity for oxygen less than or equal to carbon in the molten steel.
