The invention relates to a transfer pipe for melting metals and manufacturing method thereof, especially a transfer pipe for zinc alloy melt and manufacturing method thereof. The invention is lining an inside lining layer made from the refractory material on the inner surface. The inside lining layer is directly cast on the refractory material on the inner surface; the invention also sets the steel tube integrated into the pipeline by the amorphous refractory ramming refractory steel construction fixed on the inner surface of the structure. Since the invention of refractory material used in steel-lined floor structure of the refractory layer does not melt in the liquid zinc alloy, non-polluting liquid zinc alloy. It has high strength, high temperature, good thermal insulation performance characteristics, the same time, the invention also has good thermal insulation to reduce the liquid metal in contact with air, thus reducing the oxidation of liquid metal, therefore, can be greatly reduced when the casting alloy oxide slag.
