Abstract
A strip casting apparatus is disclosed comprising a tundish for receiving and holding molten metal and an orifice passage defined between two spaced lips through which the molten metal is delivered to a casting surface located within about 0.120 inch of the orifice passage and movable past the orifice passage at a speed of from 200 to 10,000 linear surface feet per minute. In the apparatus of the present invention at least one lance is disposed with a tip of the lance directed toward a cavity in the tundish adjacent at least a portion of the material defining at least one of the lips of the orifice passage. Equipment is provided for delivering reactive gases through the lance and into the cavity, and at least one aperture is provided through which combustion products from the reactive gases escape the cavity in the tundish. One lip defining the orifice passage of this invention may comprise a molten metal resistant plate. The improvement of this invention comprises a heat conductive layer in the cavity in the tundish at least at a location where the reactive gases from the lance impinge against the tundish material.
