Based in Gemona del Friuli,Italy, MORE s.r.l.supplies a wide range of technologies and auxiliary equipment for electric arc furnaces used in the steel-making industry. The accurate measurement of oxygen is critical in the steelmaking process. Too much oxygen causes over-oxidation (decarburization), which requires expensive re-work to obtain steel of suitable quality.Too little oxygen, on the other hand, slows production. The application therefore demands measurement devices that enable accurate control of the injector feed oxygen-fuel ratio. MORE had been using differential pressure (DP) flow meters to measure the oxygen flow in its electric arc furnaces with little success to meet customers demand for even more accurate control, as well as changing process requirements. MORE decided to implement Emersons Rosemount vortex technology. Rosemount 8800 Vortex flowmeters feature a unique design that addresses the limitations of traditional vortex flow meters. Its signal filtering (Adaptive Digital Signal Processing-ADSP) and a mass-balanced sensor design maximize measurement reliability and eliminate the impact of vibrations on measurement accuracy. In addition, to meeting customer demands for greater flexibility in their furnace installations, the 25:1 rangeability of the 8800 helps to optimize gas heaters, providing greater opportunities to vary the characteristics of the steel for different applications. And while DP flow meters can have up to 30 leakage points, the gasket-free sensor design of the Rosemount 8800 vortex flowmeters means there are no potential leak points, reducing maintenance requirements and enhancing safety.
