▎ 摘　　要

NOVELTY - The device has sample boat A (4) and sampling rod A (15) that are connected by a pusher device A (1) slides along a slide rail (14) is pulled out or pushed into the high temperature process chamber (7). The sampling rod B from a pusher device B (12) and one end of the boat by the B device connected to or separated from a sample boat B (8). The sample boat B and the sampling rod B are connected by the pusher device B slides along the pulled out or pushed into the high temperature process chamber. USE - Circulating continuous large-scale graphene film preparation device. ADVANTAGE - The graphene has excellent mechanical, thermal, optical, electrical and other properties, in many fields, and has broad application prospects. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of the working state.
