Embodiment 1
[0020] A TiC-FeCr-Gr composite material annealing furnace roll laser forming method, comprising the following processes:
[0021] (1) Raw material formula and pretreatment
[0022] The raw material formula is: graphite 0.91wt.%, Ti5.88wt.%, Cr23.21wt.%, rare earth oxide 0.33wt.%, Fe balance; the raw material is in powder form, and the particle size of metal powder and graphite powder is 60 microns; Metal Ti powder and mixed rare earth powder were ball milled together for 2 hours; Fe powder and Cr powder were ball milled together for 1.5 hours.
[0023] (2) Powder feeding and mixing
[0024] The powder feeding process is completed by a multi-hopper screw powder feeding mixing system. Put Ti powder and mixed rare earth powder into the first hopper, graphite powder into the second hopper, and Fe and Cr mixed powder into the third hopper ; Three powder feeders feed powder at the same time, and adjust the content of TiC in the forming part through the screw speed.
