Powder metallurgy powder, welding material milling, atomization boron nitride nozzle let atomization medium get the high energy
and high speed, is one of the key components for the stability of atomization process,good performance BN ceramic nozzle need
meet the following requirements:
(1) the atomization medium can be obtained as much as possible the outlet velocity and the required energy;
(2)ensure that the atomization medium and alloy liquid flow have the most reasonable injection angle;
(3) alloy liquid flow to produce the maximum turbulence;
(4) the work stability is good, the spray hole is not easy to block;
(5) easy to manufacture.
Using hot pressing sintering preparation of hexagonal boron nitride has excellent resistance for high temperature performance, anti metal melt and slag erosion resistance, high thermal conductivity, high electrical insulation, and easy processing properties and high machining accuracy, low coefficient of friction.Boron nitride ceramics are an ideal material for alloy powder flow nozzle and flow guiding tube.
