Abstract

The invention belongs to the technical field of joint coke production, and particularly relates to a special heating furnace for joint coke production, which comprises a furnace body, a chimney, a convection chamber, a radiation chamber, a burner and a furnace tube, the furnace body is provided with a furnace wall cast by adopting a castable, the inner wall of the furnace wall is provided with a compact ceramic lining, and the surface of the lining is sprayed with a high-temperature-resistant coating. The convection chamber is arranged on the upper portion of the radiation chamber, the burner is located at the furnace bottom, and a furnace tube is arranged in the furnace body. Light castable and a compact ceramic radiation chamber lining are adopted, a high-temperature-resistant energy-saving coating is sprayed on the surface of the lining, the heat dissipation loss of the surface of a furnace body is reduced by 3%, a high-efficiency, low-excess-air-coefficient and low-NOx burner is adopted, it is ensured that flue gas is environmentally friendly and qualified, after the heating furnace is adopted, the control and adjustment mode of the heating furnace is more intelligent, the labor intensity of personnel is reduced to a certain extent, the utilization rate of fuel gas is greatly improved, and the operation benefits of the device are improved.

Description

technical field [0001] The invention belongs to the technical field of joint coke production, and in particular relates to a special heating furnace for joint coke production. Background technique [0002] Joint coke is needle coke for ultra-high power graphite electrode joints. Needle coke is a high-quality carbon species vigorously developed in carbon materials and is the main raw material for the production of high-power ultra-high power graphite electrodes. Due to the good graphitization properties of needle coke, high-power and ultra-high-power electrodes produced with it have excellent electrical conductivity, thermal shock resistance and oxidation resistance. Compared with ordinary electrodes, the use of ultra-high power electrodes made of needle coke in electric furnaces can shorten the smelting time by 30-50%, save electricity by more than 10-20%, and increase the production capacity by 1.3 times. The economic benefits are very significant. [0003] The purpose of ...
