In one embodiment, 1-1.2 parts by weight of rare earth elements are added into the surfacing material in order to refine the structure and improve the wear resistance.
The invention also provides application of the surfacing repair material, and the surfacing repair material can be applied to the single-tooth roller of the sintering machine.
In one embodiment, the single-tooth roller of the sintering machine is provided with a plurality of roller teeth and a rotating shaft for driving the roller teeth, the roller teeth are square, the crushing surface of the roller teeth is a bottom surface, and the surfacing repair material is overlaid on the bottom surface and the end surface far away from the rotating shaft to form an L-shaped wear-resistant surfacing layer, so that the service life of the single-tooth roller of the sintering machine can be prolonged.
In conclusion, the invention has the following beneficial effects:
(1) the surfacing repair material has the characteristics of high hardness and strength, and has remarkable impact and wear resistance at high temperature;
(2) when the sintering machine single-tooth roller is used for crushing the sintering material, the sintering material can be mixed with certain high-hardness stones or metals, the surfacing repair material can well prolong the service life, and the work interruption caused by shutdown repair and the economic loss caused by frequent repair are avoided.
