[0002] The quartz heating tube is an economical and environmentally friendly heater with a quartz tube as the outer wall and a conductive heating element inside. It can heat up quickly after power is turned on. It can be divided into carbon fiber heating tube and iron-chromium-aluminum heating tube according to the different built-in heating elements. Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%. It is the best in high temperature resistance among all chemical fibers. It is made of acrylic and viscose fibers and is oxidized and carbonized at high temperature. It is an excellent material for manufacturing high-tech equipment such as aerospace. Carbon fiber heating tubes require different clamping devices at different production stages.
