PURPOSE:To continue production of a multilayered strip by rapidly cooling and solidifying molten metal in a heat resistant vessel with a rotating small diameter roll, rolling in gap between the above roll and a synchronously rotating large diameter roll and next joining with new forming strip. CONSTITUTION:The small diameter roll 3 rotating at high speed is arranged below the heat resistant vessel 1 of silica tube, etc., and the large diameter roll 4 roundly contacting with the roll 3 and synchronously rotating is arranged. The molten metal in a vessel 1 is spouted and rapidly cooled on the small diameter roll 3 by pressure of inert gas from a nozzle 2 to form a first layer 5 of the strip. The first layer 5 is rolled under pressurizing in the gap between the small diameter roll 3 and the large diameter roll 4 and carried along the inside of the large diameter roll 4. Next, newly a second layer is formed on the first layer 5 and joined. By this method, the rapidly cooled multilayered strip is continuously produced through the rolls 3, 4. |
