Abstract

A method of controlling a bar processing mill having an outlet and a cooling bed for producing bar of predetermined cold length. The method includes, for a first bar in a work order, calculating a long hot cut length based at least in part on a predetermined cold length. In addition, the method includes: if the long thermal cutting length is greater than the minimum cooling bed length, and if the number of layers of rods to be processed on the cooling bed is less than a predetermined value, adjusting the long thermal cutting length according to the total length of the rods output from the outlet.

Description

technical field

[0001] The present invention relates to systems and methods for controlling a bar working mill. More specifically, the present invention relates to systems and methods for determining the optimum thermal cut length to minimize the number of cold saw cuts when processing bar stock. technical background

[0002] In a typical bar mill, customers order bars at a predetermined cold length (ie, the finished length of the bar). A typical bar working mill has a crop and divideshear for cutting the hot bar coming out of the bar mill stand and a cold saw for cutting the bar on the cooling bed The final cut is made after the length has cooled.

[0003] In the case of special bar mills, such as special steel (SBQ) mills, many customer orders are for relatively small batches of bars. It is usually not economical to start up a rolling mill for a single small order, therefore, multiple small orders have to be processed together. Customer requests for custom steel models...
