A Look at BOF Steelmaking

In basic oxygen furnace (BOF) steel production, also known as basic oxygen steelmaking (BOS) or the basic oxygen process (BOP), liquid iron (hot metal) is mixed with steel scrap and alloys to produce steel.

The liquid iron, or hot metal, is generated by melting iron ore in a blast furnace. The hot metal is poured into a refractory-lined ladle, and later into a BOF vessel that has been charged with cold scrap. The alloys are added and oxygen is blown into the carbon-rich molten iron at high speeds to melt the scrap and alloys, resulting in the oxidation of carbon and impurities and the formation of steel.

Once the fluxes and metal have completed the blowing cycle, the BOF vessel is tilted, and the molten steel is poured into a ladle with basic refractory lining for further refining.

Lime Handling Systems for BOF Steelmaking

An evaluation of your lime handling equipment is essential in ensuring lime is transferred from silo to furnace in the most effective and reliable way, as over time this will be impacted through normal wear and tear. From offloading to flow promotion and conveying, Carmeuse is committed to providing quality equipment solutions to BOF steelmakers to help optimize your operations.

Carmeuse supplies our advanced equipment solutions for lime storage and handling through our wholly owned subsidiary, Storage & Transfer Technologies (STT). Our expert engineers can design the right solution to keep your steelmaking operation running smoothly, from new lime handling systems, to retrofits and upgrades for your existing equipment. Experienced technicians are also available for onsite diagnosis of current problem areas, recommendations for potential solutions, and help with system implementation and startup.
