Improved internal cooling of rollers in curvilinear continuous-casting machine

In the electrosmelting shop at OAO MMK, the internal cooling of the rollers in a curvilinear continuous slab-casting machine with a vertical section has been improved. To ensure stable heat extraction from the slab and stable difference in water temperature between the roller input and output, the rational flow rate of the cooling water within the rollers is calculated. On that basis, the water required for internal roller cooling is reduced, for slabs of different width.
