Hot Refractory Repair Services (HRR)
Cetek offers several options in refractory maintenance that can be performed while the furnace is at operating temperature. All offer exceptionally fast payback, compared to the costs associated with conventional repairs which require the heater be shut down.
Repairs may be made by making access through the steel shell directly behind the damaged area. Minimal openings are used to insert specially designed components to support the repair material. This technique offers a semi-permanent repair method, since the high quality refractory material is provided with full structural reinforcement.
Repairs may also be made using existing access points and a Hot Gunning, or Hot Fiber Spray technique, in combination with Cetek’s patented lance technology. If access points are not available, Cetek’s Hot Access Creation may be used as an integral part of the repair process. In some applications, Cetek’s LancescopeTM system is used to see hard to reach areas.
