Product Description
Core Functions and Objectives:
Adapt to process changes: Automatically respond to dynamic working conditions such as changes in drawing speed, steel grade switching, and tundish replacement to ensure the stability and consistency of cooling.
Reduce human error: Replace the manual water distribution mode that relies on human experience, and improve the accuracy and repeatability of control.
Energy conservation and consumption reduction: Precisely control water volume to avoid waste of water and energy caused by excessive cooling.
Digital control interface
Main components of the system - Metallurgical model (core) :
Dynamic model: Different from fixed water distribution meters, it can adjust the water volume in real time according to the drawing speed changes, maintaining the matching of cooling intensity and solidification rate. The methods include temperature calculation models, control strategy models, proportional control, parametric control, closed-loop control of surface temperature, and control solidification position.
Basic automation system: Receives flow setting value instructions from process computers. The water flow to each cooling circuit can be precisely controlled by regulating the speed of the water pump through a regulating valve or a frequency converter. Real-time monitoring water pressure, valve opening degree and other parameters of each circuit is carried out, and the results are feedback to the process computer to achieve closed-loop control.
Advanced metallurgical models: Model accuracy is at the core of system performance. Precise thermal physical parameters of steel grades (thermal conductivity, specific heat, density, latent heat of solidification, etc.) and reliable heat transfer boundary conditions (heat transfer coefficient) are required.
