Factors affecting the performance of refractory castables

Words:[Big][Medium][Small] Mobile Page Two-Dimensional Code 2018-10-15     

There is no difference between the basic properties of refractory castables and refractory concrete. They are all one type of refractory material and belong to the type of refractory material, that is, bulk cast refractory material. If we want to ensure that the quality of the refractory castables is not affected, then we must first analyze and study and summarize. The factors affecting the performance of refractory castables and their causes can ultimately guarantee the excellent performance, service life and market competitiveness of the products.


 


Generally, the classification of refractory castables is carried out by raw materials (high alumina, corundum, silicon carbide), bulk density, refractoriness, acidity and alkalinity. Due to the wide variety of refractory castables, Yuken Kiln Company Li Huichao does not list them one by one. In general, “the factors affecting the performance of refractory castables” are as follows: It is worthy of our attention:


 


1. Quality, content, impurities and stability of refractory raw materials.


2. The proportion and grade of refractory aggregate and powder and the degree of thickness.


3. Bonding agent (model or label and adding amount).


4. Mixing and adding amount of raw materials and water-cement ratio.


5. The effect of acid-base pH.


6. Construction and maintenance of refractory castables and changes in baking temperature and season of refractory castables (construction temperature).


7. Shelf life of refractory castables.


8, production process and operation.


9. Various physical and chemical properties and physical and chemical properties of refractory castables (bulk density, apparent porosity, flexural strength, load softening temperature, line change rate, etc.).


10. The environment and changes in the use of refractory castables (factors affecting the use of refractory castables).


11. The performance of the same product of different refractory castables manufacturers is also different.


In addition to the above factors, there are other various factors that are directly or indirectly affecting the high temperature performance of the refractory castable and the factors and causes of the life. Therefore, we must strictly and standardize the operation of refractory castables to ensure the excellent characteristics of refractory castable products.
