What are the types of waste incinerators and the refractory materials used?
Waste incineration is an important industry for purifying the ecological environment, and reducing the volume and harm of waste is an effective way to alleviate waste pollution. Common waste incinerators include plasma decomposition furnaces, rotary kiln incinerators, grate furnaces, chain furnaces, and co-processing kilns in cement plants. Different types of incinerators can achieve a certain level of combustion efficiency and the purpose of purifying and disposing of waste.
How to avoid frequent shedding of castables at the kiln mouth?
During the cement clinker calcination process, the kiln mouth rotates rapidly with the kiln body and is located in a position that is affected by rapid changes in temperature. This area requires special attention and maintenance during production.
Application of high-quality hydration-bonded castables
Since the first manufacture of castables with reduced cement content based on the French Prost patent, the formulation of refractory castables has undergone significant improvements. Recently, technical characteristics of LCC, ULCC, and NCC castables have been developed along with their construction technology, extending their application to high-temperature and severely erosive environments where only fired refractory […]
Steel Production and Processes

What’s The Difference Between Electric Arc Furnace And Intermediate Frequency Furnace?
In the realm of steelmaking, there are two different types of electric furnaces: electric arc furnaces and medium frequency furnaces.
Despite some similarities, they have distinct differences based on their principles, classifications, and advantages.
How To Reduce High Temperature Erosion Of Magnesia Carbon Bricks？
arbon-magnesia is a composite refractory material that is made by combining magnesia and carbon. It is widely used in various industries due to its unique properties. Magnesia is known for its exceptional resistance to slag erosion, while carbon boasts of high thermal conductivity and low expansion. This combination makes carbon-magnesia a versatile material with a wide range of applications.
How To Choose Lightweight Refractory Clay Bricks?
Lightweight clay brick is a lightweight thermal insulation-shaped product used for the thermal insulation layer of the furnace lining at a temperature of about 1100 °C.
