Flame gunning repair for coke oven
Flame Gunning Repair on coke oven walls
Krosaki Harima Corporation supplies a special Flame Gunning Repair service employing oxygen and propane as fuels, in which fine silica particles are fused instantaneously and transferred in a high temperature flame so that they then adhere to the damaged portions of the chamber wall.
The repair is characterized by
＊Firm adhesion of the gunned material to the wall brick surface
＊Little rebound material loss
＊Even surface after installation
Development of vitreous coating technology
We have developed a vitreous coating technology effectively controlling gas leakage or carbon adhesion to the wall surface. Major applicable targets of the coating are the coal charging holes of coking chambers and ascension pipes where significant carbon adhesion is often observed.
