PCT No. PCT/JP92/00316 Sec. 371 Date Sep. 14, 1993 Sec. 102(e) Date Sep. 14, 1993 PCT Filed Mar. 15, 1991 PCT Pub. No. WO92/16323 PCT Pub. Date Oct. 1, 1992.A process for producing a thin metallic strip by continuous casting, comprising forming a pouring basin portion for a molten metal between a pair of rotary cooling drums respectively having shafts parallel to each other and a pair of side gates in contact with the end faces of the cooling drums and pouring molten metal into the pouring basin portion for molten metal to continuously cast a thin cast strip, characterized in that the casting is conducted while vibrating the side gates at a frequency, f (Hz), determined according to the following formula in a direction substantially horizontal to an imaginary line formed by connecting the shaft centers of the cooling drums to each other: aA+b+cV</=f</=50(1) wherein A is the numerical value of the amplitude (mm) of the side gate at the kissing point portion of the cooling drum and is in the range of from 0.5 to 5 mm; V is the numerical value of the casting rate (m/min) previously determined from a desired casting sheet thickness; and a=2, b=5, and c=0.1.
