A method for manufacturing a roll mantle or roll body for a roll line of a continuous casting apparatus that has a shaft includes casting a metal to form the roll mantle or roll body such that the roll mantle or roll body includes at least one internal channel. The roll mantle or roll body has a first end region, a second end region and a central region between the first end region and the second end region, the central region extending along at least 50% of a length of the roll mantle or roll body, and the internal channel may be formed in the central region. The internal channel may also include a pattern or projection.

A heat sink assembly for a cage for a field replaceable computing module includes a heat sink, a thermal interface material (TIM), and an actuation assembly. The heat sink includes fins and a mating surface positioned at a base of the fins. The TIM includes a first surface that is coupled to the mating surface of the heat sink and a second surface that is opposite the first surface. Thus, the second surface can engage a heat transfer surface of a field replaceable computing module installed adjacent the heat sink. The actuation assembly includes a rotational cam. When the rotational cam is in a first position, the second surface of the TIM contacts the heat transfer surface of the computing module. When the rotational cam moves to a second position, the second surface of the TIM is moved a distance away from the heat transfer surface of the computing module.
