The utility model provides a graphite assembly for a polycrystalline silicon reduction furnace, which comprises a clamping body, a silicon core mounting hole penetrating through the clamping body is formed in the middle of the clamping body and is used for fixing a silicon core; one side end face of the graphite base is connected with the electrode, and the other side end face of the graphite base is connected with the clamping body and abuts against one side end of the silicon core; a fixing hole is formed in the middle of the fastener, the graphite base is sleeved with the lower end of the fixing hole, and the middle of the fixing hole abuts against the side face of the clamping body so that the clamping body can be fixed to the graphite base; and the top of one side, far away from the graphite base, of the clamping body is a plane or a conical surface. By using the graphite assembly for the polycrystalline silicon reduction furnace, the graphite assembly can be effectively prevented from being coated and e
