(1) Refractory materials for carbon black fuel furnace. In order to improve the production efficiency and the reaction degree, the reaction temperature must be increased in order to improve the production efficiency and the reaction temperature. If you want to produce hard ![04-2[1]](https://123yilong.files.wordpress.com/2014/03/04-211.jpg?w=300&h=300)
carbon black, you must also improve the reaction temperature. In particular, the production of long life, rolling wear small tires will need a more rigid carbon black, the reaction temperature of 2000 ~ 2100, which requires more than the refractory.

(2) Slag gasification device. It is well known that the gas industry is widely used in refractories. The operating temperature and pressure of the refractory material used in the gasification equipment are extremely harsh, and the operation temperature and pressure are high: the slag belongs to the acid slag which has very strong corrosion resistance. At the same time, there is a highly corrosive gas. Refractory materials used for high resistance to acid slag corrosion can be used to obtain high life.
(3) The oil cracking unit: the operating conditions in the catalytic cracking unit are the most 
demanding operating conditions, including high temperature and high pressure. The refractory lining of the catalytic cracking unit is required to have high wear resistance and low thermal conductivity so that the two contradictory properties. Because of the high wear resistance generally requires high density, and low heat conduction rate generally requires a lower density, so it is needed to introduce the two properties of the material and its related problems.

This chapter mainly discusses and analyzes the fire resistance of these special applications in the petrochemical industry, and provides the basis for the development and application of the relevant refractories.
