Structure of refractory brick can also cause brick burst

Structure of refractory bricks will burst and its product itself also has the very big relations. Refractory brick thermal spalling, refers to the subject of the refractory brick thermal shock, in refractory brick surface and internal temperature difference, because of differences in thepresence of internal expansion, leading to refractory brick masonry produce stress, when the stress accumulation caused to a certain extent is the heat burst. So, cause the refractory brick thermal spalling reason which to have:

1, silica brick mineral phases such as quartz, tridymite, cristobalite, due to the temperature change and also accompanied by quartz crystal type conversion, volume change, so the heating or cooling brick masonry structure, the need to pay particular attention to the problem of thermal explosion.

2, magnesia brick and magnesia chrome brick, because its thermal expansion coefficient is larger, the thermal decrepitating temperature mutation is also easy to produce refractory brick.

3, insulating refractory brick, because of its low thermal conductivity, the temperature gradient in brick, and because of its relatively low strength, so it is also easy to produce hot crack problems.

As the introduction, is it right? Ofrefractory bricks have a further understanding of it; the content above is only for your reference, the specific reasons but also according to the specific circumstances to determine. More detailed content of http://www.yilongrefractory.com
