Competitive Price for Graphite Electrodes With Cylindrical Nipples - UHP 550mm Graphite Electrode – Hexi
Graphitization is a very important stage in UHP graphite electrode production. It refers to the high-temperature heat treatment process of carbon products above 2300 ℃ in a high-temperature electric furnace to convert amorphous chaotic layer structure carbon into a three-dimensional ordered graphite crystal structure. What’s the funtion of graphitization? *Improve the electrical and thermal conductivity *Improve the thermal shock resistance and chemical stability (the linear expansion c... -
OEM Customized Ultra High Power Graphite Electrode - UHP 450mm Graphite Electrode – Hexi
Graphite electrodes play an important role in steelmaking industry, they are often used to melt the scrap in electric arc furnaces(abbreviated as EAF) . There are some key properties which determine the quality of electrode, what are they? The coefficient of thermal expansion (abbreviated as CTE) refers to a measure of the degree of expansion of a material after being heated, when the temperature increases by 1°C, it causes the expansion degree of solid material sample in a specific direction... -
