<p>The present invention relates to a twin-roll strip caster that can adjust thermal expansion of cast rolls by controlling a flow rate of molten steel discharged from each discharge hole. The twin-roll strip caster includes a meniscus shield provided above a pair of cast rolls to interrupt molten steel from being brought into contact with air; a pair of cast rolls disposed at both sides; an immersion nozzle provided in the meniscus shield and formed with discharge holes for discharging the molten steel from a turndish; and an opening/closing nit provided in the immersion nozzle to be able to move in a vertical direction, thereby adjusting a flow rate of the molten steel discharged from the discharge hole by controlling opening or closing of the discharge hole.</p> |
