Abstract
PURPOSE: To continuously manufacture a coated soft small-size tube with excellent productivity by performing automatically annealing and the formation of cupper alloy film on the surface of the small-size tube molded of strip steel while transferring it in the direction of axis.
CONSTITUTION: A small-size tube 1 molded of a strip steel is passed through a strainer 3 and a guide roll 4, and then copper or a copper alloy wire 15 is melted and sprayed onto the surface of the small-size tube 1 through a flame-coating nozzle 17. The small-size tube 1 so treated is then passed through core tubes 10, 10', and 10", through a high-frequency induction heater 6a consisting of high-frequency heating coils 11a, 11b, and 11c, and further through a heating surface 6b provided with a resistance heating body 12 in such a way as to melt the powdery metal (e.g. Cu) adhered to the surface of the small-size tube in order to form a thin metal film on the whole surface of the tube. And, the small-size tube is sent to a cooling zone 7 where a nonoxidative protective gas, e.g., a modified heavy hydrocarbon gas, hydrogen gas, ammonia-decomposed gas, etc., is blown into the core tube 10" through an inlet 14 to cool the small-size tube.
