Iron Making

The ironmaking process includes the blast furnace (BF) and direct reduced iron (DRI). The blast furnace is the most common ironmaking process, where iron ore is reduced to pig iron by coke and limestone in a blast furnace. The direct reduced iron process is used to produce sponge iron by reducing iron ore with natural gas or coal in a shaft furnace.In the blast furnace, the hot air blast is injected into the furnace to burn the coke, producing CO and heat to reduce the iron ore.···

Our Comprehensive Iron Making Solutions

Our solutions optimize top gas analysis and desulfurization in blast furnaces for efficient reduction.

Blast furnace gas: The gas produced in blast furnace mainly contains carbon monoxide(CO), carbon dioxide(CO₂), oxygen(O₂) and hydrogen(H₂). Controlling combustion efficiency in the furnace and keeping safe operation of the bag filter needs a continuous monitoring of above gases.

Hot blast stove flue gas: Real-time monitoring of carbon monoxide(CO) in the flue gas ensures safe operation of the stove.

In BF and CDQ, LGA measures O2, H2S, and H2 with ppb sensitivity, preventing explosions and optimizing desulfurization for 98% efficiency. Purge integration reduces downtime by 20%, complying with ISO 11047 for top gas analysis in ironmaking.
