Product Details

Glass furnace brick refractory material AZS brick

Fused Cast AZS are the most widely used materials both in glass contact and superstructure of glass melting furnaces.

The products have passed the ISO international certified,are made of high pure material,

fired at high temperature by advanced technology,

with the advantages of

high strength,high compression resistance,

good thermal shock resistance,

good perfomance in high temperature,

good thermal conductivity,

good erosion resistance and so on.Widely be used for linings of furnace in industries.

Our company can produce serious specification fused cast 33#,36#,41#AZS block for glass furnace ,and its output is over 5000tons per year. In the enormous working premises—more than 6600square meters, there are one 5tons outside cooling electric arc furnace, high-power transformer, thaw craft with computer control system and internal advanced fused cast refractory umeral caontrol grinding equipments according to its body producing ability.

We can produce common shaped and irregular shaped refractory brick.And we can adjust our specifications for your application.
