On the 17th, the only 100,000 tons/year coal-based needle coke plant of Shanxi Hongte Coal Chemical Co., Ltd., the only company capable of industrialized production of coal-based needle coke and the only company with independent intellectual property rights in this technology, was officially operating in water. Linkage test, marking China has built the world's largest coal-based needle coke industrial production equipment. Needle-shaped coke is divided into two types: oil-based needle coke and coal-based needle coke. Needle coke is the main material for manufacturing large-size high-power and ultra-high-power graphite electrodes. Graphite electrodes made of needle coke have heat resistance. High impact strength, high mechanical strength, bulk density, small thermal expansion coefficient, good oxidation resistance, low electrode consumption, and allowable current density. Only the graphite electrode produced by the needle coke as raw material can meet the requirements of ultra high power electric furnace smelting process. At present, the global needle coke production capacity is approximately 1 million tons/year, and the total demand is above 1.3 million tons/year. Demand continues to increase year by year. It is reported that currently there are only 7 needle coke makers in the world, and production technology is mainly concentrated in a few developed countries, of which coal-based needle coke Japan only controls its production technology, and China's imported needle coke prices continue to rise year by year. Shanxi Hongte Coal Chemical Company specializes in deep processing of coal tar, and has already owned dozens of national advanced technology invention patents and core proprietary technologies. In 2005, the company invested in the construction of the first domestic 50,000-tonne/year coal-based needle coke unit and achieved mass production in 2007. In 2008, the company expanded another set of 100,000 tons/year coal-based needle coke devices. It is expected that it will have trial production conditions in May of this year. When it reaches production, it will alleviate the shortage of resources in China's needle coke market and promote the electric furnace refining in China's steel industry. Steel technology upgrades.
