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.

G-high graphite electrodes are made from petroleum coke and needle coke, using coal tar pitch as agglutinant, produced through the process of calcining, mixing, kneading, compressing, roasting, graphitization and machining, etc.
G-high graphite electrodes have the properties of superior electric conductivity and chemical stability, high mechanical strength, less impurity, seismic performance in high temperature. G-high graphite electrodes are mainly used for steel-making in electric furnaces, mineral hot furnaces and electric resistance furnaces.
Graphite electrodes conduct electric current into the furnace. Electric current produces arc in the smelting district, when the temperature increases to about 2000¡ãc, smelting begins. Our series of graphite electrodes are applicable to the common furnaces and high power furnaces with high voltage and short arc. G-high graphite electrodes are classified into three classes.
Np graphite electrodes: mainly used in common power electric ovens for smelting steel, smelting silicon and smelting yellow phosphorus;
Hp graphite electrodes: mainly used in high power electric ovens for smelting steel;
Uhp graphite electrodes: mainly used in ultra high power electric ovens for smelting steel.
