Early detection of potentially hazardous locations in the furnace bottom (low remaining refractory thickness) is still difficult. Test drillings are made in the bottom to determine the remaining thickness of the refractory. Problem areas are most frequently found near boosting and bubbling systems.
Depending on the furnace type, fused cast or chrome based material is inserted into the furnace chamber by our special water-cooled carriage.
As a result of our experience we can judge the amount and distribution of the granulate required and place it in the damaged area.
We always try to disturb the production as little as possible. In certain cases different procedures may be required, and these are always discussed in detail and agreed with the customer.
This repair method is a further attractive way of prolonging furnace lifetimes at a relatively low cost.
