Efficiently environment-friendly graphitization furnace cooling technology

Abstract

The invention provides an efficiently environment-friendly graphitization furnace cooling technology. The efficiently environment-friendly graphitization furnace cooling technology comprises the following specific steps of: step 1. increasing a material absorbing depth and a material absorbing frequency step by step by using a multifunctional traveling crane and taking time as a moving direction, and controlling the temperature reduction range of a product to be less than 30 DEGC / h, when the product is exposed, the surface temperature of the product is less than 400 DEG C; step2. screening a heat preservation material in a main storage bin of the multifunctional traveling crane; and step 3. carrying out dedusting on the screened granules. The multifunctional traveling crane provided by the invention is used for the graphitization furnace cooling technology and can independently complete the cooling process. Due to the adoption of the multifunctional traveling crane, the cooling time of the graphitization furnace is shortened, the working efficiency is improved, the production cost is reduced, and the environmental protection level of the graphitization furnace in the cooling process is increased.

Description

technical field [0001] The invention relates to a cooling process of a graphitization furnace, in particular to a process method for controlling the cooling process of a graphitization furnace by using a multifunctional crane. Background technique [0002] After the graphitization furnace is powered up to 2900°C, the heating process is completed and enters the cooling stage. In the production cycle of isostatic graphite products, the heating process generally takes 10 to 15 days, while the cooling process can last for about 30 days in order to avoid product damage caused by excessive cooling. The heating process is limited by the production requirements of product performance, and its adjustment space is small, while the cooling process needs to be strictly controlled at key process points, the shorter the process, the better, and there is a large room for flexible adjustment. [0003] During the heating process of graphitization power transmission, because graphitization r...

Problems solved by technology

However, this method has many disadvantages: 1) It is difficult to operate the material grabbing process, it is difficult to accurately control, and it is easy to cause oxidation of the product; 2) After the material is grabbed, an independent cold material bin needs to be configured outside the furnace; 3) During the material grabbing and unloading process, there will be A large amount of dust is formed, which is not conducive to the environmental control of the workshop; 4) After the insulation material is placed in an external site, since the particle size distribution of the insulation material powder is 0~1mm, it is difficult to recycle all of it, resulting in continuous waste; 5) The material grabbing process requires Driving and personnel cooperate to complete the furnace body, and there are potential safety hazards
