Tungsten copper wear resistance material for a lining of a blast-furnace tuyere sleeve,
which is prepared by the following raw materials in percentage by weight:
40-60% of nano copper powder, 36-56% of nano tungsten powder, 0.2-0.65% of iron
powder and 4-6% of chromium powder. Metal conducts plastic deformation and is
molten and diffused at high temperature and high pressure and by the aging
effect at the high temperature and the high pressure, so that the
high-temperature wear-resistant tungsten copper material is obtained. The high
temperature wear resistance material of
tungsten copper is good in heat-conducting property, high-temperature strength
and high-temperature wear-resistant property, can realize metallurgical bonding
with a fine copper substrate, and can be used for manufacturing the lining of
the blast-furnace tuyere sleeve, which is good in wear-resistant property and
long in service life; the wear-resistant property of the blast-furnace tuyere
sleeve can be improved greatly; and the service life of the blast-furnace
tuyere sleeve can be prolonged greatly.
The
tungsten copper wear resistance nano-powder materials were milled, depending on
the ratio of copper powder mixed 2_4h, first at the bottom of the prepared
graphite mold Xianpu about O. 5_ thick layer of pure nano-tungsten-copper
resistant materials and then mixed in different proportions holes and pure
copper powder powder, copper content increased, the thickness of about I. 5mm,
the surface layer of about O. 5mm holes and ー thick pure copper powder.
