High-precision blade can be identified as the direction of the blade industry

Update:07 Aug 2017
Summary:

?? High-precision blade can be identified as the blade […]

?? High-precision blade can be identified as the blade industry is the direction of development, the blade has the following four important properties:
1, high temperature hardness will not be reduced.
2, by high pressure will not be deformed or broken.
3, long time will not be used to wear.
4, will be processed into a very sharp cutting edge shape, nor bending deformation.
???
In order to prevent and reduce these damage in the blade production, it is important to note the following:
1, for the blade chipping, roll edge or gap, to strengthen the retention of particles in the material, it should use cobalt content of the material.
2, for crescent and hot cracking, to use high-temperature performance with a large number of titanium carbide or tantalum carbide material.
3, for the cutting edge loss, you have to increase the content of tungsten.
???
Blade production process:
1, remove the appearance of the oxide layer, preheating.
2, heated to 800 degrees Celsius above the tungsten steel material will gradually sintering to the body slowly shrink.
3, will reduce the tungsten steel material to continue to heat the firing liquid.
4, gradually cooling to room temperature, making tungsten steel cooling molding.http://www.460663.live/
