The present invention provides a silicon carbide crystal growth method and device, the method comprising: (1) assembly stage: (2) sublimation stage: controlling a plurality of partitions to rotate between the plurality of partitions and the inner wall of the partition and the cavity There is no gap between them, the first crucible is separated from the second crucible, and the silicon carbide raw material is heated to sublimate; (3) Crystal growth stage: control multiple partitions to rotate between multiple partitions and / or the inner wall of the partition and the cavity There is a gap between them, and the second crucible communicates with the first crucible through the gap, and the heating makes the silicon carbide raw material atmosphere pass through the gap to the seed crystal for crystal growth. By controlling the rotation of multiple partitions, the first crucible is separated from the second crucible, and the sublimated atmosphere of the silicon carbide raw material cannot be transmitted upwards, so as to avoid the formation of defects affecting the crystal quality and damage and pollution to the seed crystal caused by the unstable atmosphere in the early stage of growth. And the separator blocks the heat radiation from the raw material to the seed crystal, avoiding the sublimation of the seed crystal surface caused by the lack of silicon carbide atmosphere supplement during impurity removal.

The invention discloses a high-speed hydraulic intelligent packaging device for regenerated metal broken / loose materials. The device comprises a base, and a first side plate and a second side plate are riveted to the two sides of the upper surface of the base correspondingly. A bearing plate is riveted to the upper ends of the first side plate and the second side plate. A supporting plate is riveted to the upper surface of the base, and strip-shaped grooves are formed in the inner side of the supporting plate. The back of the first side plate and the back of the second side plate are fixedly connected with a back plate. Strip-shaped holes are formed in the back plate. A pneumohydraulic pressure cylinder is embedded in the middle position of the interior of the bearing plate. The lower end of a piston rod of the pneumohydraulic pressure cylinder is fixedly connected with an extrusion platform. Telescopic sleeves are embedded at the two ends inside the bearing plate. The high-speed hydraulic intelligent packaging device can conduct effective extrusion on the waste metal loose materials, so that intervals between waste metal are reduced; and meanwhile, magnets can attract iron powder in the extrusion process, and the situation that floating iron powder pollutes surroundings is avoided.
