ABSTRACT:
A lance and method for injecting particulate matter into molten metal is disclosed. The lance includes an injector conduit for introducing particulate matter into a molten metal. A heat removal site surrounds at least a portion of the injector conduit. An insulating sleeve surrounds at least a portion of the heat removal site to minimize heat transfer from molten metal. The lance is placed in molten metal and a coolant gas is circulated through the heat removal site while particulate matter is injected into the molten metal.
