REFSOURCE

The reheat furnace application is a critical part of the steel making process. Based on two different operations...continuous and batch, the furnaces can vary in length, capacity, width and thermal profile. Based on the furnace conditions, each will have a specific refractory design and configuration to maximize success.

Customer Goals:

The specific definition of a “successful refractory lining project” on a reheat furnace will vary with each project. Because both products and installation are inter-related on most reheat projects, the following goal components are usually relevant...

  • Up front design assistance, drawings, etc.
  • High performance, cost effective products
  • Professional, experienced installation crews
  • User friendly products
  • Excellent quality control on production to maximize consistency and up time.
  • Constant supply chain control, stocking options and JIT delivery
  • Dependable on-site assistance and supervision

URC Approach:

Because the repair, relining or initial lining of a reheat furnace is a complex “puzzle” ...with many pieces that are specifically critical to the specific user, URC uses our 4U Service Approach to address reheat furnace projects.

When we understand the specific needs and puzzle pieces of the user, we offer resources from our 4U Service Toolbox that address a user’s specific goals. Examples of these URC resources are listed below under the 4U Toolbox drawers:
