00012/11.01.2010<br />
The Manufacturing Process of the composite metal<br />
material being used for producing the retention aprons in<br />
the centrifugal rotary crushers is characterized by the fact<br />
that a mixture of hard metallic carbides (with W, Ti etc.)<br />
and fused tungsten carbide, mechanically-milled and<br />
selected, are infiltrated inside a metal matrix based on Fe,<br />
Co or Ni.<br />
The Infiltration Metal Matrix, based on Fe, comprises<br />
carbide generating elements.<br />
The Composite Metal Material is made from a mixture<br />
of hard metallic carbides (with W, Ti etc.), mechanicallymilled<br />
and selected and tungsten carbide, milled and<br />
melted, with a granulation of 200 – 1500 μm, infiltrated<br />
