Petroleum coke Calcination Dancarbon Blog

2021-2-4  Calcined petroleum coke is a process of discharging moisture and volatiles from raw materials, and is heated to 1200~1500°C through high temperature. If it is not calcined first, shrinkage and deformation will occur during the subsequent firing of the electrode, causing the electrode to break. Generally, the calcination temperature is higher ...

2021-10-28  Calcination in simple words can be described as a process of heating some solid material or a substance in a controlled environment. Usually in the process, the temperature is also regulated. Calcination is done to bring about some change in the substance physical or chemical constitution. During calcination, solids are heated at high temperatures.
