The invention discloses iron-based pre-alloyed
powder prepared through recycled
nickel and
cobalt and a preparing method. The
powder is composed of iron,
nickel,
copper,
cobalt and
chromium according to a certain proportion. The method comprises the steps of firstly, component detection, wherein an artificial
diamond wastewater chemical electrolytic
recovery waste
nickel and
cobalt plate is analyzed, and the content of nickel and cobalt is determined; secondly, material preparing, wherein according to the detected nickel and cobalt content result, iron, nickel,
copper, cobalt and
chromium are calculated, and according to the total weight of
graphite powder :
metal,
graphite powder is prepared; thirdly, water atomization powder making, wherein the prepared
metal is placed in an
intermediate frequency furnace,
nitrogen is used for forming a gas curtain, air is isolated, after the
mixed metal is molten, the
graphite powder is added, and
liquid metal is crushed and atomized into
alloy powder through high-pressure water; fourthly, screening blending, wherein the prepared
alloy powder is sieved, and is sufficiently blended in a mixing
machine, and the pre-alloyed powder is obtained. The method is reasonable in formula, simple in production technology, low in powder
oxygen content, uniform in
granularity and good in cold pressing molding, and has the wide application prospect in
diamond cutters and tool structural parts.
