What kind of refractory material is used in the hearth of reverberatory furnace?
The alumina fiber has a maximum resistance of 1700 degrees, and the zirconium fiber is generally 1700 to 2200 degrees
The use of temperature ceramic fiber long 950-1260 in general, there are many domestic manufacturers do not understand the deceive customers, often in accordance with the classification of temperature to the material sold to customers, such as zirconium ceramic fiber belongs to the 1400 type, but the long-term use temperature of 1260 degrees or less, impossible to maintain 1400 degrees to 1260 degrees, so the equipment in order to use ceramic fiber, high grade can only be used on polycrystalline fiber
1400 degrees below can use clay brick, high alumina brick; 1400 to 1700 can use mullite bricks, heavy corundum brick; more than 1700 can use zirconia brick, such as zirconia brick
