stainless steel drum in the preforming chamber protected
by argon atmosphere, the melted alloy being then
projected onto a deflective plate, where it is converted into
drops which, after solidification, are deposited onto the
cooling collector bed.
Applicability Domain: production of precursors for

The Wear Preventing Shield With Self-Protection
consists of a support of sheet metal made of thermoresistant
steel wherein there are made channels forming a
rhombus-shaped grid in which there are deposited by
welding hard alloy layers with a crystalline grain
orientation along the mechanical stress of the shield.
The Obtaining Process of the self-protection shield is a
secvential multi-stage process type. The first stage consists
Description
in the obtaining of thermo-resistant steel support; in the
second stage the support is positioned in the pump cooled
welding device; in the third stage, there are made channels
as rhombus-shaped grid wherein there are deposited hard
alloys by multi-layer welding. In the fourth stage, the
shield is stress-relieved and heat smoothed.
Applicability Domain: anti-wear protection of the active
surfaces of the power plants fan mills.
