[0003] However, the above structure for rigidly slipping the quartz tube for installation has the following defects:

[0004] Defect one: due to the inherent characteristics of the shaped silicon aluminum ceramic fiber heat insulation block, the ceramic fiber whiskers grow continuously and become longer after high temperature heating, and the rigidity of the whiskers decreases accordingly, so after a period of high temperature use, when the quartz tube (about 100 kg) needs to be installed again, the shaped silicon aluminum ceramic fiber heat insulation block will be broken and powdered, and the heating wire inside the furnace body will be broken and fail.

[0005] Defect two: during the installation of the quartz tube, the surface strength of the silicon aluminum ceramic fiber heat insulation material is lower than that of the quartz, which causes the quartz tube to scratch and crack the heat insulation material during installation, and the quartz tube bumps and crushes the heating wire, causing the heating wire to deform and collapse, forming a local heating area of the heating wire, and melting and damaging the quartz tube during production.
