Cecal - TECHNOLOGY YOU CAN TRUST

Stave coolers are critical components in blast furnace operation, providing thermal protection to the furnace shell and supporting the stability of the cooled area throughout the campaign. Unlike other components that can be addressed during regular maintenance shutdowns, staves are not easily removed or replaced, making long-term reliability a key factor in their specification and procurement.

CECAL designs and manufactures stave coolers engineered to withstand severe operating conditions, including high thermal loads, burden abrasion, shell deformation, and furnace process variations. The company’s experience allows it to address critical design and manufacturing points, reducing risks related to cracking, leakage, premature wear, and bonding failures between the copper body and internal cooling elements.

Manufactured in copper and special alloys, CECAL stave coolers combine high heat extraction capacity, structural robustness, and strict control over casting, fabrication, welding, machining, and inspection processes. Each component is developed according to the blast furnace’s operating conditions, with a focus on long service life, operational stability, and reduced need for interventions throughout the campaign.
