Abstract
A method of controlling the amount of hydrogen in steel for consistent heat transfer in continuous casting by adding a hydrocarbon to the molten metal. A heat of molten steel is formed in a ladle metallurgy furnace adapted for use in continuous casting. Then, a hydrocarbon is added to the molten metal in the ladle metallurgy furnace in an amount sufficient to increase hydrogen levels in the molten steel for casting. And finally, the molten steel with a desired level of hydrogen is delivered to a caster to continuously cast a steel product.
