Embodiment Construction

[0019] The core of the present invention is to provide an ultra-high temperature graphitization equipment in combination with the graphitization process, and the ultra-high temperature graphitization process of the ultra-high temperature graphitization equipment is relatively continuous and efficient.

[0020] In order to enable those skilled in the art to better understand the solutions of the present invention, specific implementations will be further described in detail below in conjunction with the accompanying drawings.

[0021] The graphitized sample 10 of the present invention is fed by the feeding system 7, and reaches the primary preheating furnace 1 through the material passage 8 of the feeding track. The heating rod 11 is arranged in the furnace, and the primary preheating furnace 1 is closed. Heating in the primary preheating furnace 1 from room temperature to 1200°C, and then opening the heat preservation and sealing system 2; entering the secondary preheating furn...

Abstract

The invention provides a novel ultra-high temperature graphitization furnace. The graphitization furnace comprises the following core parts: an enclosed system part, a carbonization part, a graphitization part, an air inlet and outlet part, a material charging and discharging part, a cooling part, and the like. A phased heating and cooling is used, time taken by cooling in the process of graphitization is reduced, the material charging and discharging system enables continuous operation of the graphitization process, frequent blowing out for carrying cooling and taking of the material is not needed in the whole technology implementation process, the process flow is continuous and highly efficient, the whole carbonization processing process is more stable and reliable, the product specification has good adaptability, subsequent splicing and other operations are not needed, and utilization rate and applicability of the product are substantially improved. Production efficiency is substantially improved and production cost is reduced.

Description

technical field [0001] The invention relates to an ultra-high temperature graphitization furnace, which belongs to a high-temperature heating device. Background technique [0002] Ultra-high temperature graphitization furnace is widely used for high-temperature graphitization of carbon fiber, flake graphite, carbon material structural parts (products), C / C composite material products, carbon materials and other graphite materials. At present, the batch process is often used in the ultra-high temperature graphitization process, which is inefficient, and the temperature range of the ultra-high temperature furnace is large, which consumes time and energy. Contents of the invention [0003] In view of the above problems, the present invention divides the high-temperature furnace into different heating intervals, shortens the heating range, reduces the waste of time caused by large-scale cooling, and improves the graphitization efficiency. [0004] For this reason, the present...
