Patent no. RO125587/30.01.<strong>2012</strong><br />
RETENTION APRON for centrifugal crushers, whose active<br />
region consists of a composite material with embedded metallic<br />
carbide with composition: C = 0,6...0,9%; Mn = 1,5...5%; Si =<br />
0,7...1%; Cr = 1...2%; W = 2...5%, Fe = rest %; the metallic<br />
carbides result from mechanical grinding of worn waste mixed in<br />
equal proportions with angular granules obtained from melted<br />
and grounded tungsten carbide powder having dimensions of 800<br />
... 1500 μm; the metallic carbides waste have the folowing<br />
composition: WC = 95%, Ctotal= 3,81%, Cfree = 0,02%, Fe ≤<br />
0,21%, Cr ≤ 0,038%, V ≤ 0.01%, Ti ≤ 0,01%, Mo + Co + Ni <<br />
0,045%).<br />
APPLICABILITY DOMAIN: manufacturing of anti-wear<br />
resistance structures of the natural aggregates grounding<br />
installations.<br />
