The invention relates to a metallurgy sintering fuel breaker roll repairing technology and belongs to the technical field of a sintering roller repairing method. The service life of a repaired breaker roll is prolonged by means of the metallurgy sintering fuel breaker roll repairing technology. The technical scheme of the metallurgy sintering fuel breaker roll repairing technology is that bead weld is carried out by the adoption of three kinds of welding sticks in a layering mode. Multiple times of heating processing technological processes are carried out among layered bead weld processes and after the whole bead weld is finished so that the three bead weld layers can be firmly connected and metallic characteristics of different bead weld layers are fully made use of and finally, the breaker roll is repaired. The metallurgy sintering fuel breaker roll repairing technology is scientific and reasonable in design, easy, convenient and feasible in technological process and capable of effectively prolonging the service life of the repaired breaker roll. The service life of the repaired breaker roll can be prolonged to be 6-8 months. Thus, the repairing frequency of the breaker roll is reduced, maintenance cost is reduced, labor intensity of workers is reduced and the aim of continuous production is ensured. The problem which haunts technological personnel in the industry for a long time is solved and an outstanding contribution is made to improvement of economic benefits of enterprises.
