Abstract
A method for controlling a bar processing mill having an exit and a cooling bed to produce bars of a predetermined cold length. The method includes, for a first bar in a processing order, calculating a long hot cut length based, at least in part upon a predetermined cold length. In addition, the method includes adjusting the long hot cut length based on a total length of bar exiting the exit, if the long hot cut length is greater than a minimum cooling bed length, and if a number of layers of bars to be processed on the cooling bed is less than a predetermined number.
Claims22
A method for controlling a bar processing mill, having an exit and a cooling bed, to produce bars of a predetermined cold length, the method comprising:
- for a first bar in a processing order, calculating a long hot cut length based, at least in part upon a predetermined cold length;
- and
- adjusting the long hot cut length based on a total length of the first bar at the exit, if the long hot cut length is greater than a minimum cooling bed length, and if a number of layers of bars to be processed on the cooling bed is less than a predetermined number.
A system for controlling a bar processing mill, having an exit and a cooling bed, to produce bars of a predetermined cold length, the system comprising:
- a first bar identifier for identifying a first bar in a processing order,
- a long hot cut length calculator for calculating a long hot cut length based, at least in part upon a predetermined cold length;
- and
- a long hot cut length adjuster for adjusting the long hot cut length based on a total length of bar exiting the exit, if the long hot cut length is greater than a minimum cooling bed length, and if a number of layers of bars to be processed on the cooling bed is less than a predetermined number.
A method for controlling an SBQ mill having an exit and a cooling bed to produce steel bars of a predetermined cold length, the method comprising:
- for a first steel bar in a processing order, calculating a long hot cut length based, at least in part upon a predetermined cold length;
- and
- adjusting the long hot cut length based on a total length of bar exiting the exit, if the long hot cut length is greater than a minimum cooling bed length, and if a number of layers of steel bars to be processed on the cooling bed is less than a predetermined number.
A system for controlling an SBQ mill having an exit and a cooling bed to produce steel bars of a predetermined cold length, the system comprising:
- a first steel bar identifier for identifying a first steel bar in a processing order,
- a long hot cut length calculator for calculating a long hot cut length based, at least in part upon a predetermined cold length;
- and
- a long hot cut length adjuster for adjusting the long hot cut length based on a total length of bar exiting the exit, if the long hot cut length is greater than a minimum cooling bed length, and if a number of layers of steel bars to be processed on the cooling bed is less than a predetermined number.
