Merkle International, Inc. has a proven suspended refractory system for lead smelting operations--the Merkle Roto-Patch® system. The Roto-Patch system utilizes pre-fired refractory shapes along with metallic hangers and structural steel-for support. These pre-fired shapes generally have a longer installed life and higher resistence to corrosion than plastic or castable systems.
Merkle has extensive experience in suspended refractory systems, dating back to 1973. Merkle works with its customers to find the best long-term solution for their particular smelting situation. Our staff will work with you to determine the exact refractory quality that fits your process and your budget.
Roto-Patch® is a suspended basic brick assembly.
Roto-Patch® is for heavy duty suspended roofs and tied-back walls. The primary uses in the lead industry are smelter roofs and bullnoses.
Advantages of Roto Patch® Assemblies
- The rotating, self-locking hanger allows the assembly to be hung either parallel or perpendicular to the support pipe, for maximum repair flexibility.
The single rotating Roto-Patch® hanger replaces either of the
two hangers required for competing
designs, and means a reduction in inventory of up to 50%.
- The suspension rods, with up to 80% greater cross-sectional area than competing designs, provide better oxidation resistance.
- The suspension rods and castings can be ordered in a variety of
heat resistant materials including chrome-nickel alloys.
- The refractory shapes can be ordered in standard lengths or as required by the customer.
- Roto-Patch® assemblies can be used for new installations as well as patching, and are suitable for panelizing.
- Roto-Patch® is interchangeable with existing designs.
As a supplier of innovative equipment and systems, Merkle is also a problem-solver.
The Best in the Business
Merkle works in conjunction with customers in the lead industry and delivers what the customer needs. Our scope of supply can include structural support steel supporting our refractory system. We can also provide fabrication details for that steel, for local fabrication (saving shipping costs). In addition to supplying our innovative and highly functional products, we purchase and inspect material, and provide technical support during installation.
