▎ 摘　　要

NOVELTY - The quartz bracket (200) has a first bracket that is provided with the three first rolling rings, the first rolling rings are arranged in sequence along the extension direction of the first bracket, and the adjacent first rolling rings have different positions and heights. A second bracket is arranged opposite to the first bracket and is provided with three second rolling rings. The second rolling ring corresponds to the first rolling ring one-to-one, and the position of the second rolling ring is the same height as the corresponding position of the first rolling ring. The connection line between the second rolling ring and the corresponding first rolling ring is perpendicular to the extending direction of the first bracket. The first rolling ring and the second rolling ring are used to support and transport the copper foil on which graphite is to be grown, and the first support, the second support, the first rolling ring and the second rolling rings are made of quartz material. USE - Quartz bracket for use in quartz heating device (claimed) of graphene production system. ADVANTAGE - The efficiency of graphene production is improved, and the quality of the graphene is improved, while adhesion of the copper foil in the furnace tube and the quartz tube wall to cause the graphene to wrinkle or tear is avoided. The copper foil is prevented from contacting the furnace tube, and the area of the copper foil in the furnace tube is increased without increasing the diameter and length of the furnace tube, thereby the area of a single graphene growth is increased. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a quartz heating device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the quartz bracket.
