Reducing shutdown time.
“Shotcrete” is a wet method for the application of special monolithic refractory materials. Premixed, pumpable refractory castables are conveyed to the place of application with special high pressure pumps (approx. 250 bar) over distances up to 80m and more. The castables are “sprayed” with compressed air through a special nozzle. Simultaneously an accelerator is added and mixed in the nozzle, which guarantees the bond and stability of the applied castables at their installation locations. Compared with conventional refractory casting castables, the “Shotcrete” method achieves nearly the same properties (density, strength).
No complex formwork is need for the application which reduces shutdown time and costs for the customer.
