Reasons for firebrick heat burst phenomenon

The reason for firebrick heat burst phenomenon. Do you know the reasons for the phenomenon of heat burst firebrick emerge? Below I explain for your detailed introduction about it:

1, magnesia or magnesia-chrome brick, due to the large thermal expansion coefficient, while also prone to sudden changes in temperature firebrick heat burst.

2, the mineral phase constituted of silica brick, such as quartz, tridymite, cristobalite, due to the temperature change is accompanied by crystal transformation of quartz, along with the volume of mutation, so the heating or cooling brick masonry structure, special Note heat burst problem.

3, insulating firebrick, because of its low thermal conductivity, a large temperature gradient of the brick body, and because of its relatively low intensity, so it is easy to generate heat burst problem.

The above is a brief burst phenomenon firebrick heat reason, I hope for your help, more product information, please feel free to contact us or login inhttp://www.yilongrefractory.com.
