Abstract
The continuous casting of steel is supervised and controlled by measuring total heat flow and the ratio of upper to lower heat flow into the mold and causing these two valves directly or indirectly to be represented in a two dimensional field. The resulting operating point must remain within an empirically predetermined range for safe operation without skin rupture.

Method for supvervising the continuous casting of steel, comprising the steps of:
- detecting the amount of heat flowing into at least a circumferentially partial section of the casting mold and providing a measuring value representative thereof;
- detecting as separate quantities the heat flows, respectively, into the mold in upper and lower portions of that section and providing measuring values representative thereof;
- computing the ratio of the measuring values representing the heat flows into the upper and lower portions;
- forming an operating point from the measuring value in accordance with the first detecting step and said ratio and
- referencing the operating point to a predetermined range.
Apparatus for supervising continuous casting of steel by means of a mold having walls which have a path through which flows a coolant, comprising:
- first means for detecting the amount of heat flowing into at least a partial circumferential section of the casting mold and providing a measuring value representative thereof;
- second means for detecting separately the heat flows into the mold in upper and lower portions of that section and providing, respectively, measuring values representative thereof;
- third means for computing the ratio of the measuring values as detected by the second means;
- means for forming a manifestation of an operating point from the measuring value as provided by first means and the ratio as computed by the third means;
- and
- means for referencing the operating point or its manifestation to a predetermined range.
Method for controlling the continuous casting of steel, comprising the steps of:
- detecting the amount of heat flowing into at least a circumferentially partial section of the casting mold and providing a measuring value representative thereof;
- detecting as separate quantities the heat flows, respectively, into the mold in upper and lower portions of that section and providing measuring values representative thereof;
- computing the ratio of the measuring values representing the heat flows into the upper and lower portions;
- forming an operating point from the measuring value in accordance with the first detecting step and said ratio;
- and
- controlling the casting process in dependence upon the operating point.
