Why should refractory bricks increase toughness

Refractory bricks have a certain degree of toughness, and their quality will be more demonstrated when they are used. Therefore, when we use the product, we must pay more attention to it. Refractory materials are generally divided into two types, namely, unshaped Refractory materials and shaped refractories. Unshaped refractories are also called castables. They are mixed powdered particles composed of a variety of aggregates or aggregates and one or more binders. They must be mixed with one or more liquids and mixed evenly during use. Strong liquidity.

Although the refractory bricks look hard, there is still a risk of cracks. This time, their service life is greatly reduced. Therefore, toughening treatment is required during production. Why should refractory bricks be toughened?

Due to the structure of refractory bricks, pores and cracks are inevitable. If there is an external force, the cracks are easy to start, and there is no energy consumption mechanism, so brittle fracture is prone to occur.

The toughening of refractory bricks can make some adjustments to its structure, reduce the size of cracks, control the number of impurities and the number of pores and the distribution. It is also possible to avoid the spread of cracks by increasing energy consumption or the setting of obstacles.
