Abstract

The article describes an example of a casting and rolling complex. A program has been developed for calculating the temperature of the metal in the casting and rolling complex sites which is based on a mathematical model for controlling the water cooling of a rotary mold in TIA Portal software using an S7-1200 microprocessor controller. Presents the structure and user interface of the program. The program blocks of the rotary mold, as well as the section of water and air cooling are developed, which include design and thermophysical parameters necessary for calculating according to the mathematical model. In this way, the replacement of any of them with a similar one with modified parameters is possible without making changes to the program structure. The program can be used to debug control algorithms.

Highlights

Development of programs for the calculation on these models will allow you to visualize the rolling process, as well as debug control algorithms on a virtual model, determine the optimal process parameters for various alloys
The casting and rolling complexes, which include a rotary mold, consist of: a ladle for metal tapping onto the casting wheel 1; mold 2 which is a rotating belt wheel with a notch of trapezoidal section on the rim and pressed onto the rim of an endless steel tape; a water-cooled wedge for the extension of the continuous cast billet; rollers correct device 3 through which the billet passes; cooling zones 4; device for temperature equalization across the section; break-down mill in which a square semi-finished product is formed from trapezoidal billet; storage device 5, on which the obtained rod is wound [3]
The program block FB1 of the rotary mold performs the calculation of the temperatures of the casting wheel and the billet; includes the design parameters as well as the thermophysical parameters of the material from which it is made
