Abstract

A roll line unit for a continuous casting apparatus includes a roll mantle having two ends and a non-rotatable shaft including a coolant line. The roll mantle is rotatably mounted on the non-rotatable shaft by means of a first bearing located in a first end region of the roll mantle and a second bearing located in a second end region of the roll mantle. The roll mantle includes at least one coolant channel having at least one fluid inlet that is arranged to be in fluid communication with the coolant line. The roll line unit includes two outer seals located on an axially outward side of each of the first and second bearings, whereby the outer seals and the first and second bearings are located axially inwards of the ends of the roll mantle.
