Several Advantages of Using Phosphate Bricks in Small Rotary Kilns

Phosphate bricks and wear-resistant bricks are both of the phosphate bonded high alumina kiln lining bricks. Phosphate bonded high alumina bricks use phosphoric acid solution or aluminum phosphate solution (aluminum dihydrogen phosphate, PA-80 glue, etc.) as the binder, bauxite clinker as aggregate, and press molding. It is a chemically bonded refractory bricks product made by … Read more

Factors Affecting High-Alumina Wear-Resistant Plastics

Circulating fluidized bed boiler (CFB), as a major “clean combustion” device, is widely used in new or rebuilt fire (thermal) power plant projects. And it drives the continuous improvement and development of refractory materials for CFB boilers. The CFB boiler has a complex lining structure, and there are a large number of high-concentration, high-speed circulating … Read more

Features of High-Performance Light-Weight High Alumina Castable

Light-Weight High Alumina Castables mainly use lightweight aggregates and heavy fine powder. Lightweight aggregates used in Light-Weight High Alumina Castable have larger pore diameters and lower strength. Therefore, the thermal conductivity of the lightweight castables is higher. At the same time, the low aggregate strength affects the overall strength of the lightweight castable, limiting its … Read more

A Certain Amount of Cr2O3 Can Enhance the Corrosion Resistance of High Alumina Castables

What is a high alumina brick? What is high aluminum castable? High alumina castable is a refractory castable made of high-alumina cement clinker as a stone and granular materials, adding flux and thickener. The raw material of the integral lining can be poured immediately, or it can be poured into the fireproof preform for application. … Read more

High Alumina Castable Refractory

Broadly speaking, as long as the test results, refractory castables with aluminum (AL2O3) content ≥ 42% can be called high alumina castable refractory. It has high mechanical strength and good resistance to thermal shock and abrasion. From the composition structure, the high-aluminum castable refractory is a refractory castable made of bauxite clinker as aggregate and … Read more

Castable Refractory for Heating Furnace

The heating furnace is operated at high temperatures, and the working temperature is generally below 1400°C. Castable refractory for heating furnace is essential. Due to the change of temperature, a certain temperature gradient is formed, and the lining of the high temperature furnace gas is easy to fall off. The refractory material for the furnace … Read more
