The selection of the appropriate refractory castable needs to consider a variety of factors, including the use of the environment, the physical and chemical properties of the refractory, construction conditions and budget. Here are some common choices:
1, the use of the environment: first of all, you need to understand the use of the environment, including temperature range, corrosive media, REDOX properties, etc. Different environments require different types of refractory castables.
2, the physical and chemical properties of refractory materials: refractory castable is usually composed of powder, polymer, additives and water, and its physical and chemical properties can be determined according to its composition. For example, aluminate castables have good resistance to high temperature, wear and corrosion. Silicate castable has excellent fire resistance and high strength. Magnesium aluminum castable has good alkaline resistance and corrosion resistance.
3, construction conditions: When selecting refractory castable, it is also necessary to consider construction conditions, such as pouring method, construction speed and construction amount. For the need for rapid construction, fast drying castable can be selected.
4, budget: Finally, according to the project budget and material prices and other factors to choose the appropriate refractory castable. Generally speaking, the price difference between different types of refractory castables is large, and it is necessary to weigh and choose according to actual needs.
To sum up, the selection of refractory castables requires comprehensive consideration of factors such as the use environment, physical and chemical properties of refractory materials, construction conditions and budget, and testing and verification in practical applications. At the same time, attention should be paid to the selection of refractory castables that meet national standards and quality certification to ensure its quality and safety performance.
