Usage:
Graphite petroleum coke can be widely used as carbon raiser (Recarburizer) to produce high quality steel, cast iron and alloy.Excellent performance and stability. Proper carburizing agents can help reduce the cost of smelting and improve the quality of smelting metals and castings.
Semi-coke is light black; characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content,
low sulfur and Low phosphorus; wildly applied to such industries as chemical industry, metallurgic industry, gas-making
industry, etc.; used to produce Calcium Carbide,Ferrosilicon, FerroNickel,Silicon Carbide, Silico Manganese, Fertilizer, etc

Used for iron manufacture, steelmaking, non-ferrous metals smelting so on.
Both blast furnace coke and foundry coke are made by baking a blend of selected coking coals in certain high temperature without contact with air until almost all of the volatile matter is driven off. The resulting product, coke, consists principally of carbon, as listed in above table. By-products are crude coal tar, light oils, and ammonia, etc.
Generally speaking, chemistry, size, and strength have been considered the most important properties for use in the blast furnace. Other important factors are coke reactivity and csr (coke strength after reactivity), which deal with the amount and size of pores and walls, porosity, and density. Carbon textures and microstructure are two main factors that affect the reactivity, stability, and the coke strength after reaction.
G-high graphite petroleum coke is widely used as carburant in the steel-making industry and precision casting industry, reduction pregnant agent in the casting industry, reducing agent in metallurgical industry and as one kind of refractories, etc.
G-high graphite petroleum coke could promote the nucleation of the graphite in liquid iron, increase the amount of spheroidal graphite, and improve the structure and the grade of grey iron.
Based on the microstructure observation, the features of g-high graphite petroleum coke are as the following:
First, it can greatly increase the proportion of ferrite content of the nodular cast iron without pearlite stabilizer; second, it can increase the percentage of v and vi shaped graphite when it is used; third, comparing with the improvement of the shape of spheroidal graphite, the great increase of spheroidal graphite amount can decrease the usage of expensive nucleating agent for later micro-adjustment and save the cost remarkably.

By strictly practicing yb/t 192-2001, g-high carbon develops many kinds of carbon-additives according to customers'requirements, which contains high carbon, low sulphur, low nitrogen and few harmful impurities. These products are playing a very positive role in improving quality and lowering consumption in metallurgical industry, and they have been preferred by most of the major manufactures. Meanwhile, they are also widely used in chemical industry.
Since its founding, g-high carbon has made rapid progress due to increasingly improved production management and quality control system. By stable production and supply capacity, g-high carbon has been the origin for many trading companies and metallurgical factories when they look for qualified carbon additives.
