The DeltaV automation system produced by Fisher-Rosemount Inc is the new generation Control System. It's developed from the traditional DCS(Distributed Control System) and integrated with the fieldbus technique. The DeltaV is generally applied in many industry processing auto control systems. It is very advanced.In the float glass production the glass melting furnace is the most energy-intensive device of glass industry. The melting furnace,the tin bath and the annealing kiln are the important part of the whole float-glass production line, but their auto control system is the brain of them .The state of their auto control system will affect the quality and the efficiency of glass production. The float glass production enterprises of our country should apply actively the advanced technique and the advanced auto control system. The float glass production enterprises should innovate actively in technique. Only in this way, they can economize the energy and reduce the consuming. Also only in this way, they can promote the quality of the float glass and improve the competition ability of the enterprise.At first, the article describes the status of float glass production in domestic and international. The thorny problem on the traditional control technique of the float-glass production auto control system is analyzed. Follow it, the development of the auto control technique is discussed and several important kinds of fieldbus is compared. At last, we decided to adopt the DeltaV automation system to implement the float-glass production auto control system. The decision is based on the practical requirement of the float-glass production auto control system. And then, the configuration and the superexcellent function of the DeltaV is introduced. We analyzed the advantages of the DeltaV applied on the float-glass production auto control system.From the point of view of the macrocosm, the article describe the application of the DeltaV in the float-glass production auto control system . What parts of the float-glass production auto control system the DeltaV should be applied in are defined. How to control these parts importantly is analyzed. And then we present a design about the application of the DeltaV in the float-glass production auto control system. It relates to what structure should be adopted and what devices should be needed. And so the outline of the project is formed.From the point of view of the microcosm, the example about the flame reversal control of the melting furnace is set in detail to explain the processing procedure of the DeltaV. The article embody comprehensively these units :the concept, the control analysis, the structure,the configuration,the flow chart and the program of the flame reversal control and so on.Because the float-glass production auto control system has used the DeltaV, its structure is simplified, it become compatible and opening, its installation and configuration become easier, its maintenance become expedient, it become more safe and more stable, it achieve truly the good unification of the management and control in the field.Proved by the fact of the float-glass production line we completed has been running, the target for production can meet our expectancy by using the DeltaV. The float-glass production is steady-going. The auto control system is running excellently. The quality and effectiveness of the float glass manufacture got improved.
