Apparatus for applying a coating of a slurry of a powdered solder material and a binder to the inner surface of a hollow metal cylinder. The apparatus includes solder material coating device including a coating nozzle which may be moved between a coating position within the interior of the hollow metal cylinder and a non-coating position; a guide for guiding and transporting a hollow metal cylinder towards the nozzle; means for rotating and supporting the hollow metal cylinder when the nozzle is in the coating position. The solder coated metal cylinder is used, for example, to provide an exhaust gas cleaning metal carrier in which a metal honey inner core is inserted into and soldered by the solder slurry applied to the hollow metal cylinder.

A wide thin metal sheet having a smooth surface may be manufactured directly from molten metal. A lower end of a nozzle installed vertically at the bottom of a molten metal vessel is held in contact with an inclined plate made of a refractory material, molten metal is discharged in a fan-shape from a notch formed in the peripheral wall of the nozzle end, the discharged molten metal being rendered into a constant shape laminar flow having a uniform flow rate distribution on the inclined surface as it flows down the inclined plate. The constant shape laminar flow is supplied to a molten metal pool between a pair of rollers of internally water-cooled type without any disturbance on the surface and in the inside. The metal solidified in the neighborhood of a portion of the gap between the two rollers is discharged from an open-at-the-bottom space defined between the two rollers.
