Our factory which is devoted on glass industry has a annual production capacity of fused cast azs block of 30,000 tons by 10 production lines located in 3 devisions, at the same time our products dliversify from fused cast bricks to monolithic and sintered materiasls ; we have 100,000 tons per year automoated production line for advanced monolithic refractory for glass industry and cement industry and two production lines for environmental friendly basic refractory bricks with annual capacity of 80,000 tons. with regard to the silica bricks, we have a production capacity of 50,000 tons.

We have a 7000 square meters pre-assembly platform in production plant which can accomplish complete pre-assembly for five float glass process lines with capacity of 900 T/D in the same time.

Casting types

Fused cast azs block are manufactured by electro-fusing and casting process. After being poured molten material into molds, shrinkage voids occur in cooling and solidification process. The location of shrinkage voids is important for furnace design and is controlled by casting techniques as the following table.

Fused Cast AZS block Casting types

Casting types

MarkCasting typeRemark
RCRegular CastThe normal type of product including the shrinkage voids under the casting gate.
VFVoid FreeThe special type of product being removed the shrinkage voids after cooling.
ENCEnd CutFor side wall blocks, most of the shrinkage voids are removed by the same method as VF.

 

we can manufacture three types of AZS (alumina/zirconia/silica) products with varying levels of zirconia content. All three exhibit the same type of microstructure involving a high alumina sodium-silicate glass phase, monoclinic zirconia phase, and a co-precipitate phase of zirconia and corundum (corundum grains with embedded zirconia).
