Apparatus and method for adaptive control of a rolling mill

Abstract: The method of controlling a velocity dependent factor of strip material being processed in a mill includes the steps of simultaneously determining the apparent velocity of material prior to, between and subsequent to spaced apart work rolls. Input slip is determined by comparing the apparent input velocity with the apparent work roll velocity, and output slip is determined by comparing the apparent output velocity with the apparent work roll velocity. A velocity dependent factor is calculated in response to a comparison of input slip and output slip. The calculated factor is compared with a previously calculated factor and a derived factor is calculated when the calculated factor exceeds the previously calculated factor by more than the selected amount and an adaptive factor used to calculate the derived factor is calculated when the calculated factor does not exceed the previously calculated factor by the selected amount. A selected number of the calculated and/or derived factors are averaged and the divergence between the averaged factor and a target factor is used to adjust the spacing between the work rolls.

Rolling mill guide

Abstract: My invention relates to rolling mill apparatus and more especially to the guide equipment therefor and is applicable to metal rolling mills having stands of rolls known as two-high and threehigh mills, and is particularly adapted for use in connection with two-high mills of the continuous type...

Nozzle insert for a steelmaking ladle

Abstract: A two piece nozzle insert for use in a steelmaking ladle comprising a nozzle segment and a lock ring segment. The nozzle segment includes a prefired refractory block suited for insertion into the discharge bore of a ladle well block, and the lock ring segment includes a fastening means for removeably attaching the lock ring segment within the discharge bore of a ladle mounting plate. The nozzle segment and lock ring segment include cooperating tapered surfaces to provide a slip plane for compressing and extruding bonding material from between mortar joints of the two piece nozzle insert.

Multiple-Attribute-Based Expert Support System for Customer/Order Evaluation

Abstract: Sales and marketing people routinely evaluate and rank their customers to develop a marketing strategy and plan of action for utilizing available sales resources. Performing this evaluation informally makes it difficult to take into account all the significant customer attributes in a consistent and objective manner. In this paper an approach based on multiple attributes is developed to assist in evaluating customer performance. This approach is coded primarily in an expert system shell, which is run on a personal computer. The expert system shell was chosen over other software by the marketing people because they preferred its user-friendly capabilities. This system is being used by the Tin Mill Products Marketing office of Bethlehem Steel and is being considered for use by other product-line marketing offices within Bethlehem.
