| 20140116639 | COOLING CONTROL SYSTEM FOR CONTINUOUS CASTING OF METAL - Maintaining the shell surface temperature profile under transient conditions by spray water cooling in continuous casting of steel is often desired to reduce occurrence of surface cracks. For this purpose, a real-time spray-cooling control system is provided that includes one or more of: a virtual sensor for accurate estimation/prediction of shell surface temperature, control algorithm and data checking subroutines for robust temperature control, server and client programs for communicating between these software components and the caster, and a real-time monitor to display the predicted shell surface temperature profiles, water flow rates, and operating data, among other things. | 05-01-2014 |
| 20140290898 | ROLL CASTING METHOD WITH CRYOGENIC COOLING OF CASTING ROLLS - Molten metal poured into a mold region, delimited by a first casting roll that rotates about a first rotational axis, produces a metal strand upon solidification which is conveyed out of the mold region. A liquid coolant is applied to the surface of the first casting roll by a first cooling device via first coolant lines and first coolant applying devices. The coolant is inert with respect to the molten metal and has a standard boiling point below 20° C., e.g., −20° C., at normal air pressure, and an operating temperature at or below an operating boiling point at an operating pressure at which the coolant is supplied. A control device automatically controls the first cooling device by ascertaining a control state of the first cooling device using a target property for an actual property of the first casting roll or the metal strand detected by at least one sensor. | 10-02-2014 |
