This paper describes the microcomputer control of after-rolling cooling of reinforced bar, The control system is composed of three subsystems-cooler with water supply, measuring and regulating equipment, and microcomputer. The main control concept, the structure. and functions of control program has been given after the process has been analysed. The. control models and their self-adapting correction formulas required for the process are built on the basis of deducing theoretical mathematical model. It has been proved by long operation that the design and operation of this system is reliable and meets the demands of industrial production. The product properties conform the relevant technical standards, and the remarkable economic benifit has been obtained. The suggestions on further improvement in given is this paper.
