Overview

Tenova's copper products use the freeze lining principle to reduce component wear. Lower wear means longer launder life, cutting long-term maintenance costs and downtime production losses.

Cooling of the refractory lining is a fundamental aspect of furnace operations. Lining life is often determined by abnormal operating events and extreme operating conditions. To improve lining life and guarantee extended performance, particular care must be given to design, installation, drying and cleaning of the equipment together with a proper cooling system.

Water-cooled copper components use the freeze lining principle to reduce component wear. Lower wear means longer launder life, cutting long-term maintenance costs and downtime production losses. The design of Tenova Pyromet water-cooled copper components and copper launders eliminates inherent risk to personnel and equipment safety.

Using computer-aided design (CAD) and finite element analysis (FEA) techniques, Tenova Pyromet optimizes the design of copper cooling systems for:

  • Heat removal capacity.
  • Copper and lining maximum operating temperatures.
  • Cooling-water contact area and flow characteristics.
  • Temperature gradients on the lining hot face.
  • Efficient use of copper.
  • Use with heat transfer fluids other than water.

All Tenova Pyromet copper cooling elements are manufactured and tested to stringent standards to ensure products of the highest quality, capable of exceeding design performance.
