Abstract

PURPOSE: To reduce the polishing time for rolls by producing an amorphous metallic tape with a pair of rolls which consist of the same material but differ in surface hardness and producing damages of rolls only on the one roll.
CONSTITUTION: A high hardness roll 4 of ≥Hv700 surface hardness and a low hardness roll 5 having a difference of ≥Hv300 in hardness from said roll are provided, and molten metal 2 melted in a heat resistance crucible 1 is ejected via a nozzle 9 onto the surface of the roll 4, whereby it is rolled to a thin metallic strip 8. Thereby, the surface roughening of the roll 4 is eliminated at all. The roughened surface of the roll 5 is polished by a polishing tool provided. Therefore, the considerable reduction of working time is made possible.
