The replacement of fire brick is a major overhaul. If the part causes the furnace shutdown, which is also a major overhaul, so the key of overhaul is depends on what reason it is

Q:The service life of the refractory brick of the intermediate frequency electric furnace, how long is the replacement period.

There is no standard. As long as the induction coil can be fixed and furnace lining can be built, the service life will be different. Replace it if it's broken, and there is no problem to take it apart. Buy a backup. And the textures of refractory brick are not the same in different places.

Q:How to choose the proper refractory bricks when buying the refractory bricks?

Crack condition. 4. 6. Inspection of dimensions. Conditions of pits and swells and lack of edges or angles. The inspection of refractory bricks' appearance quality and the condition of the affecting with damp.

Q:can the refractory sand be used to make refractory bricks?

refractory bricks can be used as a refractory sand after crushing , no strength required results in the lower intensity, but the temperature is not high, so it is not recommended, but refractory bricks after the high temperature is fine because its properties are changed

Q:What materials make of clay insulating fireclay brick?

The aluminium silicate refractories whose aluminium oxide content is 30% ~ 46% is called clay-based refractories. Clay products mainly consist of mullite, glass phase, cristobalite and quartz.

Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?

High temperature prevention, warmth keeping and heat insulation.

Q:What type of refractory brick won't deform or crackbe for a long time in the temprature of about 1600 degrees?
