HZZG casting roller comprise a roller body, a shell fitted over the roller body and longitudinally extending coolant passages. Coolant passages are between roller body and shell. Casting roller is manufactured wherein a chromium layer is plated onto the inside surface of the shell and two overlays of stainless steel of different hardness are deposited on the surface of the roller core, thus significantly prolong the life of the casting roller. Continuous aluminum casting mill comprise a pair of parallel , water-cooled, counter-rotating casting roller. After being in use for a given period, the surface of the casting roller must be reground because of heat cracks resulting from thermal fatigue and out of roundness due to galling between caster core and shell. Accordingly, the shells surrounding the cores must be removed periodically, and the cores repaired and reground before rebuilding of the roll assembly.
