The steelmaking process involves converting liquid iron into steel via basic oxygen furnace (B0F, also known as converter) or melting scrap steel and/or direct reduced iron (DRl) in an electric arc furnace (EAF).Recovery of BOF gas is the single most energy-saving improvement in the BOF proceSs, making it a net energy producer. The BOF gas containing approximately 70-80% carbon monoxide(CO) is usually recovered in gas holder for future use.···

On-line instruments especially exhaust gas monitor are used to optimize operations of an EA. Benefits of it include reduced electricity consumption, shorter power on times, increased productivity a decrease in production costs, a reduction of electrode consumption, reduced natural gas, oxygen and carbon consumption, and are duction of refractory wear.

Our solutions enable safe gas recovery and exhaust monitoring in BOF, EAF, and CDQ operations.
L'analizzatore laser di gas (LGA) di FPI è stato perfettamente personalizzato per questa difficile applicazione. Il laser e il sensore senza contatto, combinati con lo spurgo continuo, consentono di evitare la manutenzione. Grazie alla flangia monoblocco semiaperta brevettata da FPI, l'LGA è il monitor di riferimento per i precipitatori elettrostatici di catrame, con una trasmittanza minima del laser di 70-80% in condizioni estremamente difficili. La risposta ad alta velocità (fino a 1s) dell'analizzatore in situ ne evidenzia l'affidabilità per il controllo della sicurezza. L'estrema monocromaticità dello spettro laser garantisce l'assenza di interferenze incrociate con tutte le altre specie di gas.
In EAF and CDQ, LGA tracks CO, CO2, O2, H2, and H2S with <1s response, preventing explosions and optimizing desulfurization towers for 98% H2S removal. Integration with purge systems ensures maintenance-free operation, reducing downtime by 20% and supporting ISO 11047 for gas analysis in steel making.
