At present, most design institutes and manufacturers still take a cautious wait-and-see attitude towards complex nitride combined silicon carbide bricks when selecting refractory materials. The main reason is that the cost of using complex nitride combined silicon carbide bricks will be much higher than that of mullite- Silicon carbide bricks. When considering the cost of materials, only considering the purchase price of the product is one-sided, and the overall cost of the entire life cycle of the product should be taken into account and play a decisive role. Based on the concept of "lower product life cycle cost", taking the 140t/h CDQ coke oven as an example, the cost of using different refractory materials in the chute area is calculated as follows.
