The invention discloses a
recovery processing method of hard
alloy scraps. The method comprises the following steps: a. the hard
alloy scraps and a filling agent of
charcoal black are put into a
graphite boat and put into a carbon
tube furnace to be calcined under
hydrogen at a high temperature, the calcining temperature is from 1600 DEG C to 2400 DEG C, the calcining time is from 30 min to 80 min, and the
hydrogen amount is 1.2 to 2.6m<3> / h; b. the hard
alloy scraps after being calcined at the high temperature are unloaded from the boat, cleaned on the surfaces, crushed at two stages by a jaw
crusher and a roller
crusher into alloy granules with the
granularity of 2 mm to 8 mm; c. ball milling is carried out to the alloy granules after being crushed, the ratio of
grinding media to material is (4 to 5):1, and the ball milling time is from 8 hours to 16 hours; d. alloy
powder which is obtained after ball milling is screened, and the screened alloy
powder which is detected to be qualified is used for mixing by a traditional production technology and manufacturing a hard alloy. The method adopts high-temperature
calcination so that the hard alloy scraps are extremely easy to crush and process, and the recovered alloy
powder has the same ingredients as the
tungsten carbide of the processed hard alloy scraps and a binding
metal.
