▎ 摘　　要

NOVELTY - Producing graphite carbon-increasing agent comprises (i) placing the forged petroleum coke in the vibration sieve for vibration screening, screening the large petroleum cobalt in the vibrating sieve, (ii) paving the small block of petroleum coce in the furnace bottom of the box type furnace body, (iii) placing furnace wall plate and fixing furnace core, charging material and insulating material, covering the heat insulation material on the furnace core; (iv) preparing auxiliary material, setting wood or graphite isolation layer between the furnace wall board and the petroleum co-ke, setting graphite layer between furnace head carbon block and petroleum coil, (v) mixing the periphery of the furnace type periphery is mixed with coke powder and quartz sand to prepare heat preservation material filled, (vi) recycling the waste heat, paving spring type heat exchange pipe on the surface of the tank-type furnace body and (vii) making the inner ring of the spring-type heat. USE - The method is useful for producing graphite carbon-increasing agent, which is useful in the metallurgy industry and the pig iron industry. ADVANTAGE - The method provides graphite carbon-increasing agent with high-efficiency cleaning and tail gas treatment, can recycle the tail gas waste heat, solves the problem that the graphite carbonitizing agent in the production process, is easy to cause deterioration of the quality of the graphene carbon increasing agent product, affect the subsequent use, and the discharged tail gas is not discharged, and will cause pollution to the environment.
