An immersion pouring spout for introducing molten metal, such as steel, into an ingot mold is provided with a top head and a cylindrical pouring tube including a protective external jacket attached by cement to the pouring tube and extending the entire length of the pouring tube. The jacket material has a thermal conductivity that is less than the thermal conductivity of the pouring tube material.

A blast heating apparatus includes an inner metal shell having therein a refractory lining. An outer metal shell surrounds at least a portion of the inner metal shell and defines therewith a double shell structure. Spacers are positioned between the outer and inner metal shells to define therebetween a gap. At least a portion of such gap is filled with a pourable dry material having a grain size of up to 8 mm and a heat conductivity of at least approximately 1.5 W/Km.
