Advanced Heavy Machining for Extreme Thermal Environments

In modern steelmaking and pyrometallurgical operations, thermal management is the critical boundary between continuous high-performance output and catastrophic equipment failure. Blast furnace cooling staves, electric arc furnace copper cooling panels, and furnace roof water jackets operate in some of the most aggressive thermal, mechanical, and chemical environments on earth. At Akyavuz Endüstri, located in the industrial heartland of Kocaeli / Kartepe in the Marmara Region, we specialize in the precision contract manufacturing and heavy machining of these vital metallurgical components.

Designing and fabricating high-integrity copper cooling elements requires an uncompromised synthesis of advanced metallurgy, rigorous stress relieving, and ultra-precise CNC deep hole gun drilling. Because copper exhibits high thermal conductivity coupled with unique machining challenges—such as thermal expansion and gummy chip formation—partnering with an experienced OEM manufacturer is paramount for global steel producers and OEM machine builders.

Technical Excellence in Heavy Machining & Fabrication

Manufacturing heavy-gauge copper plates and structural steel water jackets demands state-of-the-art infrastructure. Our facility features heavy-duty CNC horizontal boring machines, high-torque gantry milling centers, and heavy turning lathes capable of handling oversized raw castings and forged blocks. To ensure optimal performance within the furnace shell, we execute the following critical manufacturing steps:

  • Deep Hole Gun Drilling: Precision-drilling complex, elongated internal cooling channels over long spans with minimal deviation to guarantee uniform fluid dynamics and prevent localized hot spots.
  • Dimensional Stability & Stress Relieving: Employing thermal stabilization processes to eliminate residual stresses in both oxygen-free copper (OFE/Cu-HCP) and structural carbon steels.
  • Tight Tolerance Machining: Maintaining micron-level tolerances on mating surfaces, sealing faces, and threaded manifold connections to withstand high-pressure water loops without leakage.
  • Advanced Metrology: Utilizing comprehensive CMM inspection and non-destructive testing (NDT), including ultrasonic testing and hydrostatic pressure testing, to validate structural integrity before dispatch.
