Development Status and Suggestions of Refractory Materials for Carbon Calcining Equipment

摘要

The calcination equipment for petroleum coke or needle coke calcination is usually rotary kiln and vertical shaft kiln. Increasing the service life of refractories in calcination facility is the key to increase the utilization rate of calcination equipment, to reduce maintenance cost and even to improve the calcination quality, especially when the proportion of high sulfur and high volatile petroleum coke in current market keeps increasing. This paper states and analyzes the current situation of calcination equipment for petroleum coke and needle coke, compares the new process with the traditional one and makes a detailed analysis of the new process and market prospect, hoping to enlighten and help the technical progress in this field.
