Abstract: A method includes performing by a host system processor: receiving a record insert request for a database, the record insert request comprising a primary key value and a semi-unique key value, the database comprising a record structure comprising a first primary key field, a second primary key field, and a semi-unique key field, the first primary key field comprising a flag portion for which a first flag value is indicative of the first primary key field containing a primary key and a second flag value is indicative of the first primary key field containing an alternate primary key, generating an alternate primary key value based on the primary key value and the semi-unique key value, the alternate primary key value having a portion thereof corresponding to the flag portion of the first primary key field set to the second flag value, generating a record comprising the alternate primary key value in the first primary key field, the primary key value in the second primary key field, and the semi-unique key valu

Abstract: A method and apparatus for automatically adjusting coolant flow rates in casting machines forming a continuous casting and rolling apparatus is disclosed.

Abstract: A method for automatically adjusting soluble oil flow rates to control physical properties of continuously rolled rod including a nozzle for spraying the rod with fluid, a tank for providing the fluid to the nozzle, a valve means in series with the tank for regulating the fluid flow to the nozzle, a controller means connected to and for controlling the valve to ensure that the fluid flow reaches a desired predetermined rate, a computer means connected to and providing said controller with the desired predetermined fluid flow rate, a flowmeter in series with the valve means for measuring the actual fluid flow rate to the nozzle and providing this information to the controller means so that, if necessary, the valve means may be adjusted to achieve the desired predetermined fluid flow rate and an historical data generating means for automatically adjusting said desired predetermined fluid flow rate in accordance with actual measurements of at least one physical property of the rod whose value depends upon the ac
