Brown Fused Alumina Precast Block Unshape Refractory Block
The Description:
Refractory preforms belong to the category of amorphous refractory materials, also known as castable preforms and amorphous refractory preforms. Is to mix the good castable, through the mold pouring into the desired shape, shape diversity, superior performance, more flexible than the use of shaped products.
There are many kinds of refractory prefabricated parts, which can be divided into clay, high aluminum, silicon carbide, corundum and other prefabricated parts according to the aggregate varieties. The weight of prefabricated parts ranges from tens of kilograms to several tons, so it can be divided into large, medium and small prefabricated parts; Some prefabricated parts with reinforcement and anchor parts can also be divided into ordinary prefabricated parts, steel prefabricated parts and anchor parts prefabricated blocks.

The outstanding features of using refractory prefabricated parts are as follows:
1). It is not limited by the shape of the part used, and can achieve the characteristics of disfigurements of refractory materials. (Specific shape of individual parts of the kiln can not achieve refractory brick masonry, refractory prefabricated parts to make up for this deficiency.)
2). Superior material performance, longer service life of finished products. (Raw materials for casting prefabricated parts can be selected according to the parts of the equipment used and the working temperature.)
