Embodiment 1
[0017] (1) Use 100-mesh and 300-mesh sieves to sieve the shot blasting powder. The shot blasting powder with a particle size of 100-300 mesh accounts for 28%, and the shot blasting powder with a particle size of 100-300 mesh is used instead of cutting iron powder.
[0018] (2) The physical and chemical properties of 100~300 mesh cutting iron powder are as follows:
[0019]
[0020] (3) Add the shot blasting powder with a particle size of 100~300 mesh into the stainless steel continuous casting slab cutting iron powder tank. When cutting the stainless steel continuous casting slab, spray the shot blasting powder into the oxygen-acetylene flame instead of the cutting iron powder, and cut the steel The first type is stainless steel 316L continuous casting slab, the cutting speed is 370mm / min, the slag fluidity is good during the cutting process, and the cutting end face is neat. The test shows that 100-300 mesh shot blasting powder can be used instead of cutting iron powder.
Embodiment 2
[0022] (1) Use 100-mesh and 300-mesh sieves to sieve the shot blasting powder. The shot blasting powder with a particle size of 100~300 mesh accounts for 35%, and the shot blasting powder with a particle size of 100~300 mesh is used instead of cutting iron powder.
[0023] (2) The physical and chemical properties of 100~300 mesh cutting iron powder are as follows:
[0024]
[0025] (3) Add the shot blasting powder with a particle size of 100~300 mesh into the stainless steel continuous casting slab cutting iron powder tank. When cutting the stainless steel continuous casting slab, spray the shot blasting powder into the oxygen-acetylene flame instead of the cutting iron powder, and cut the steel The first type is stainless steel T4003 continuous casting slab, the cutting speed is 360mm / min, the slag fluidity is good during the cutting process, and the cutting end face is neat. The test shows that 100-300 mesh shot blasting powder can be used instead of cutting iron powder. ...
Embodiment 3
[0027] (1) Use 100-mesh and 300-mesh sieves to sieve the shot blasting powder. The shot blasting powder with a particle size of 100~300 mesh accounts for 50%, and the shot blasting powder with a particle size of 100~300 mesh is used instead of cutting iron powder.
[0028] (2) The physical and chemical properties of 100~300 mesh cutting iron powder are as follows:
[0029]
[0030] (3) Add the shot blasting powder with a particle size of 100~300 mesh into the stainless steel continuous casting slab cutting iron powder tank. When cutting the stainless steel continuous casting slab, spray the shot blasting powder into the oxygen-acetylene flame instead of the cutting iron powder, and cut the steel The first type is stainless steel 1Cr13 continuous casting slab, the cutting speed is 380mm / min, the slag fluidity is good during the cutting process, and the cutting end face is neat. The test shows that the shot blasting powder of 100 mesh to 300 mesh can be used instead of cutting...
