The Transformation of Control System for Bell-Type Annealing Furnace with Pure Hydrogen in Pangang Group Cold Rolling Mill

Abstract:

The transformed control system of bell-type annealing furnace with pure hydrogen in Pangang Group cold rolling mill is analyzed, and the technological process, the structure of control system, the control principle are introduced. The principles and implementations of important control functions are analyzed in detail, including security measures, the measurement and control of hydrogen flow, temperature control etc. The production practice shows that, the transformed control system stabilizes the production process, improves product quality, optimizes the production process.
