Fengcheng Ruixing Carbon Products Co., Ltd
The carbon material is heat treated at high temperature, and the water and volatilization contained in it are discharged, and the production process of improving the physical and chemical properties of raw materials is called calcining. Carbonaceous materials commonly used gas and its volatile as a heat source for calcination, the highest temperature is 1250-1350 ℃.
(1) the calcined to carbonaceous materials organization structure and the profound changes in physical and chemical properties, mainly reflected in the increase of the density of the coke, mechanical strength and electrical conductivity, improved the coke chemical stability and oxidation resistance, laid the groundwork for after order process.
(2) the calcining equipment mainly has canning calcining furnace, rotary kiln and electrocalcining furnace. Calcination quality control index is oil JiaoZhen density of not less than 2.07 g/cm3, resistivity is not more than 550 mu Ω. M, needle coke is not less than 2.12 g/cm3 density, resistivity is not more than 500 mu Ω. M.
