A class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractory resistance refers to the temperature in degrees Celsius at which a conical sample of refractory material can resist the action of high temperature without softening and melting without load. However,...
Lightweight Insulating Refractory Castable is a refractory castable with light weight, high strength and excellent thermal insulation properties. It is mainly composed of lightweight aggregates (such as perlite, vermiculite, etc.), high-temperature stable materials, binders and additives.
Lightweigh...
Insulation resistant materials are generally materials with a guiding thermal coefficient of less than or equal to 0.2. The use of good insulation technology and materials in construction and industry can often achieve twice the result with half the effort. Statistics show that every ton of mineral...
Phosphate castables are very different from aluminum silicate castables. For example, improper operation of phosphate castables will cause material to escape, increase porosity, reduce structural strength, shorten service life, and increase additional production costs. The construction methods of ph...
The key to high-aluminum castables is ultrafine fly ash and dispersants. The ultrafine powder has a small particle size and can effectively fill the pores formed by the accumulation of high-aluminum castable aggregates and fine powder, reducing the water demand for high-aluminum castable constructio...
Thermal properties and electrical conductivity of refractory balls
1.1 Thermal expansion
The GB/T7320 standard has two definitions: linear expansion rate (the relative change rate of the diameter of the refractory ball between room temperature and the test temperature, expressed in %),...
Generally, when using refractory castables, you need to pay attention to its density value in advance because castables produced by different manufacturers have different densities. This is also because there may be other substances inside that affect the density, so customers must be sure when purc...

What are the differences between clay bricks and high alumina bricks?
Clay bricks and high alumina bricks are both commonly used bricks in construction, but they are very different. The former is widely used and has more prominent advantages when building blast furnaces. In addition, in recent years...
Introduction:
In pottery and ceramics, the choice of clay is crucial, especially when it comes to heat resistance. Whether you're creating functional cookware, artistic sculptures, or industrial refractory materials, selecting the right type of clay can make all the difference. In this blog p...
High alumina brick castables are constructed by pouring or can be made into refractory prefabricated parts. The construction is convenient, time-saving and labor-saving, and the service life is twice as long as that of refractory bricks.
High alumina brick fire castables have a wide range of applica...
1. Key points of kiln roof construction technology
1. The cross-section of the reinforced concrete structural parts of the load-bearing beams of the kiln ceiling must meet the design requirements, with an allowable deviation of ±3mm in size, and the installation position should be accu...
