R.P.R.?in Coke Oven

When the silica lining of a coke oven badly needs repairing then, with a minimum of disturbance from the regular running of the plant, a hot repair is the only suitable remedy.

FIB-SERVICES has developed a special process called Reactive Projection Repair? (R.P.R.? to deal with just such a situation. It is based on the formation of a new refractory monolithic lining the restore the initial profile of the wall.

This formation is the result of the exothermic chemical reaction of a mixture projected with a machine through a lance on the hot surface to be repaired. This reactive mixture mainly containing silica cheap thailand barcelona jerseys refractory phase provides owing to the exothermic reaction a mixed oxide CaSiO3 acting as the bonding phase for both the initial brick masonry abs the refractory silica grains of the repaired product.

Advantages

Material (powder)

  1. High bulk density
  2. Low porosity and gas permeability (low carbon infiltration)
  3. High thermal conductivity
  4. High mechanical strength and abrasion resistance
  5. Excellent adhesion to the initial masonry owing to the good thermal compatibility between both materials (old and new)

Projection Machine

  1. Easy to use
  2. Only 2 Operators
  3. Powder feeding through hopper -> No pressure and no N2
  4. Light and compact : 137 kg H: 1m L : 0.80 m l : 0.60 m
  5. No moving parts
  6. No electricity and no electronics
