Coke shrinkage
Carbon shrinkage is a term in metallurgy which refers to the decrease in volume of a material when it is heated. This process is the cause of the common phenomenon of metals cracking or warping when heated (thermal shock). A wide range of materials can undergo carbon shrinkage, including carbon st......
Coke thermal stress
Carbon Black Stress Releasing
Carbon black is a common ingredient for many industrial applications. It is a pure form of elemental carbon, made by burning natural gas, oil or coal in the presence of nitrogen. Carbon black is used in the manufacture of tires, rubber products, inks, paints, and ton......
