Real-time Detection And Control System Of The Continuous Casting Process Computer

Automatization of continuous casting is to guarantee continuous casting production automatism process with aid of measuring instruction and control equipment, under conditions of no manpower intervening and according to technics demand . Continuous casting is a very complex producing process and system engineering. In order to guarantee inside and outside quality of ingot and dragging speed, parameter supervising of temperature, dragging speed, cooling water flux and fiction force between ingot and cooling model is needed.This paper develops technics parameter computer real-time measuring system. The system is used to measure temperature signal, flux signal, speed signal and motor load. It is also used to control cast speed, temperature and flux. Flux signal collection's difficulty is analyzed. The method of dummy count is created for measuring flux signal. The influence of stove's heat inertia to temperature control is analyzed. The model of two digit temperature control is established. Reverse pressing pour system is designed. The cast speed control model is created according to experiment condition.This system bases on Windows operation system and is easy to be operated. It's program language is VB and VC. It's running speed is able to satisfy real-time collection demands through using DLL, dynamic memory management and multithreading technology. The software system adopts database to save collection data so that data management and analysis is convenient.Now, the on-line system is working well in the experiment process, and it is stabile. The system has passed check and accept by school organization.
