Refractoriness is an important indicator of the quality of refractory bricks

Refractoriness, also known as refractory resistance, is not a physical constant of matter, but a technical indicator. Refractory refractoriness refers to the temperature at which a refractory material reaches a certain degree of softening under high temperature. Refractoriness is an important indicator of the quality of refractory bricks.
 

The degree of refractoriness has three important points for refractory bricks:
 

1. The refractoriness of refractory bricks is related to the raw materials, and the purity of the raw materials will affect the refractoriness. The main amount of clay clinker on the clay bricks determines the quality of the refractory bricks.

2. Raw materials with high shrinkage and low refractoriness, such as binding clay, if used in excessive amounts, will reduce the fire resistance of the clinker. For example, when manufacturing a silica brick, a part of the low-corrosion clay is added as a binder, thereby affecting the overall fire resistance of the silica brick. It can be said that the chemical composition of the ingredients determines the fire resistance of the refractory bricks.
 

3. Refractoriness can also be understood as the high temperature that refractory bricks can withstand. The higher the refractoriness, the stronger the high temperature resistance of refractory bricks and the better prototypes at high temperatures. Therefore, many customers who purchase refractory bricks first consider Its refractoriness.
 

Sunrise refractory company must point out that the refractoriness of refractory bricks is not the only factor to measure the quality of refractory bricks. We should consider them when purchasing refractory bricks, so that we can choose the right refractory bricks.
