Practical experience has proven that rotary kiln or cement kiln incineration technology can handle industrial hazardous waste in solid, liquid, and gaseous states, making it one of the most widely used hazardous waste disposal technologies today. As of July 2019, there were 75 cement kiln co-processing projects (excluding Hong Kong, Macao, and Taiwan) in China that had obtained hazardous waste operation licenses, with an approved disposal capacity of 4.6252 million tons. Currently, cement kiln co-processing of hazardous waste mainly involves solid hazardous waste, liquid waste, and RDF (refuse-derived fuel) as alternative fuels, which are fed into the system through components such as the preheater, decomposition furnace, rear kiln inlet, and kiln hood. Compared with traditional landfill and incineration methods, cement kiln co-processing of waste offers significant advantages. However, due to its late start, the technology, operation, and supervision systems are not yet fully mature.Read more

A glass furnace is a thermal equipment for glass melting constructed with refractory materials. The service efficiency and lifespan of a glass furnace largely depend on the types and quality of refractory materials. The development of glass production technology is significantly reliant on advancements in refractory material manufacturing technology. Therefore, the rational selection and use of refractory materials are crucial in the design of glass furnaces. To achieve this, two key points must be mastered: first, the characteristics and applicable parts of the selected refractory materials; second, the service conditions and corrosion mechanisms of each part of the glass furnace.Read more

Silicon nitride bonded silicon carbide materials are used to replace traditional carbon materials on the side walls of electrolytic cells. They can also serve as thermocouple protection tubes for temperature measurement, lining materials for aluminum smelting furnaces, linings for aluminum ladles ("baozi"), crucibles, pumps and pipelines for conveying aluminum liquid, valves, aluminum casting molds, and riser tubes for forming automotive wheel hubs.Read more
