Cutting Picks Surfacing with Plasma Overlay Equipment

Industry Problem:The cutting picks are in direct contact with the coal mining rock, which generates strong friction and impact during the working process, reducing the service life and working efficiency of the cutting picks Solution:Using DML series plasma power supply from Shanghai Duomu Industry Co., Ltd. and equipped with PLC automatic cladding tooling, the wear-resistant coating is overlaid on the cut-off teeth head to achieve the function of surface wear resistance and anti-corrosion.
The effect after plasma overlay welding of cutting picks
1. The wear resistance of the cutting picks is significantly improved.
Using advanced plasma overlay technology, a layer of high hardness metal ceramic layer is deposited on the head of the cutting picks, which has the characteristics of high hardness, good toughness, wear resistance and impact resistance, etc. It protects the head of the cut-off tooth very well, reduces the wear speed of the head tooth body, makes the tooth body and the alloy head wear simultaneously, and achieves a good match.
2. Bending resistance is significantly improved.
According to all goods in the use of the process of broken pear parts and check the curved condition, the use of advanced analysis software ASS on all goods for 7 miles process force broken also calculate the scale of the proposed analysis, and according to the results of the analysis developed a unique thermal external process and other production and processing of the art, so that the overall bending resistance of the tooth body and the surface strength of the tooth shank has been greatly improved, to ensure the normal use of the cutting picks.

3. use process "No spark".
Ordinary cut-off goods in the process of use especially to cut kau stone process will produce a large number of sparks, to the coal on the production of great safety hazards. Our company produces plasma pile of strong "non-sparking" cutter because in the cutter head to get a layer of high willingness of metal ceramic layer, the ceramic layer makes the cutting picks in the use of the process of reducing the amount of sparks generated by more than 90%, greatly improving the safety of coal mining.
Comparison test of sparks under the same conditions with the same grinding wheel
In the process of grinding, the bright sparks of about 60% of the length of the ordinary gears are dispersed, while the plasma welding machine strengthens the gears in the process of grinding, which basically does not produce sparks but only a very few dark sparks, and the length of sparks is only 10-20m%.
In short, Shanghai Duomu plasma welder reinforced non-sparking cutting picks have the characteristics of wear resistance, long life, not easy to break, no sparks, etc.. Not only reduce the cost of coal production, reduce the labor intensity of workers, and a good solution to the long-standing problem of coal safety production threatened by sparks generated during the use of the cutting picks. The application of plasma overlay materials, so that the cutting picks plasma welding layer performance indicators and the shape of the weld layer with variability and control: plasma alone overlay materials and the application of the overlay process, a complete solution to the brazing process on the tooth head caused by Annealing softening problem.
