| Abstract: | Cast steel cutting picks for shearer were produced from low alloy air quenched Bainite material, and flow welding was used instead of braze welding. The results show that the shearing strength of flow weld can reach over 300 MPa and is higher than braze weld. Complete picks can be heat treated. So the material and constitution of the matrix of picks can be effectively controlled. In comparison with the forged picks, cast steel picks have a good performance and low production cost. |
