China's refractory materials industry implements a regulatory system that combines competent authorities and industry associations and self-regulatory organizations. Among them, the industry competent department is the Ministry of Industry and Information Technology, which is responsible for macro m...
There are two main types of coking situations in the process of incineration waste treatment in rotary kilns, including: the first is the coking of low-melting point salts in the furnace. During the incineration treatment process, the waste will decompose at high temperatures. The decomposed element...
In the cement kiln transition zone, refractory materials are subject to corrosion and pressure from all aspects during use, resulting in a service life that is usually 40% lower than that in the firing zone.
