Method for preparing graphite crucible with recycled graphite
The invention relates to the technical field of waste graphite recycling, in particular to a method for preparing a graphite crucible with recycled graphite. The method comprises the steps of: 1) putting pitch in a pitch melting tank at 160-180 DEG C for dehydration and settling for 72h to form moderate temperature modified pitch, 2) crushing and screening the recycled graphite and calcined coke respectively to form recycled graphite powder and calcined coke powder for future use, 3) uniformly mixing the standby recycled graphite powder and the calcined coke powder to form a mixed dry material, 4) putting the obtained mixed dry material into a mixing-kneading pot for dry mixing for 35-45min, then adding the moderate temperature modified pitch for wet mixing for 35-45min, 5) cooling mixed and kneaded paste to the room temperature, 6) grinding the aired paste into powder, 7) pressing the ground powder for forming to form a crucible blank, 8) putting the obtained crucible blank in a roasting furnace for roasting, and 9) machining the qualified roasted crucible blank. The method is simple and improves product quality.
