Therefore, the high-temperature oxidation-resistant furnace coil roller has great significance for improving the product quality and developing the steel plate coil rolling technology.
At present, the furnace roller which is off-line and needs to be repaired is mainly repaired in a surfacing mode and also repaired in a spraying mode. However, the roller surface repaired by the surfacing mode has obvious stress cracks, even closed cracks, and incompact tissues, is easy to peel off, and has poor high-temperature oxidation resistance. The roller surface is repaired in a spraying mode, although some materials with strong oxidation resistance can be sprayed, the interface bonding force is weak, the coating is thin, and the coating is easy to crack and peel under the action of high temperature and contact with the plate coil.
The laser cladding technology is an efficient and convenient surface modification technology and has the following advantages: (1) the dilution rate of the cladding layer is low; (2) the heat influence on the base material is small; (3) the thickness of the cladding layer is controllable; (4) the interface bonding force is strong; (5) the tissue is fine and compact. The laser cladding process is adopted to clad the functional layer, so that the coating has high interface binding force, the coating is prevented from peeling off, a compact tissue structure can be obtained, and the oxidation resistance and the anti-adhesion nodulation capability are improved. More importantly, the high-temperature oxidation-resistant functional layer of the laser composite manufacturing furnace roller can meet the requirement of long-time use at high temperature, the oxidation nodulation of the roller surface is reduced, and the head and tail quality of the rolled plate is further improved.
