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