Earth
drilling tools We made a special tip to the drilling head. It cuts through stones and
is self sharpening. All the three shoulders, each have
self-sharpening cutting blades with tungensten
carbides embeded in a matrix of soft yet with
hardness of Rc.60. The crushed W2C have many cutting edges and cut through
materials.
Chopping
tools for composting machinary These tools are subjected to a combination of impact as chopper hits
stones etc., with high speed, and wear coming from chopping action. Impact
needs a softer and wear needs a hard surface. We achieved both by using
softer yet tough matrix enbeding hard W2C particles
in it. An extra gain is that, W2C are always fresh and sharp scratch up the
organic materials so that air contacting surface increases, promoting
composting action. The top of the chopper will not become round but keeps
sharp, because of the combination of alloys we selected.
Hammer head
for cement industry Note the sharp egdes it developes.
We have many alloy combinations, like one for softer materials cement
clickers and another for harder materials like stones, car crushing etc. Needs
less energy, as it is obvious the sharp edges make crushing action easier
with less energy. Another prominent acheivement is
the hammer does not become shorter, loosing its hammering force.
Augers Transporting very aggesively wearing
materials. We use very high carbon and crom alloy and
W2C in nickel matrix, it gives not only longer life,
but also a smother surface to fecilitate movement
of the materials.
Air wheel for
wet sand in the foundries Sand flows at high speed resulting high wear. These were made from casted W2C as spheroid particles, in nickel, bor, silicium matrix, resulting
in longer life.
Choppers This again is our special achievement to longer life and sharp edges. We
selected an alloy steel to give the sharp edges and hardfacing
alloy too so that the wear is concentrated only at the edges. This keeps the
length of chopper almost the same in all its life, thus the cutting force don`t decrease. The normal chopper becomes shorter and
shorter loosing its cutting force.
