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.

A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).
