AZS Fused Cast Blocks for glass melting furnaces

AZS Fused Cast Refractories are the most widely used materials in glass melting furnaces, frit kilns and occasionally some foundry plants(skid rails of reheating furnace). They can be classified by their zirconia content, which basically defines their corrosion resistance, into 3 families: AZS 33, AZS36 and AZS41

1. material selection advices for different parts of glass furnaces

2. check and evaluation of furnace design drawings(refractory part)

3. pre-assembly for key parts of the furnace before shipping.

4. provide total package of refractory solutions for your glass furnace

5. glass furnace design, build &commissioning services, operation training, turnkey jobs, hot repairs, cold repairs, maintenance jobs,etc..

6. outsource/inspection/supervision service for refractories and machinery equipments of glass furnaces

1. what is the service life of your AZS fused cast blocks?

service life is affected by many factors, such as the type of glass you're melting, raw materials, type of fuel, pull rate, furnace management,daily maintenance,etc..

However, for regular soda-lime bottle glass furnace under proper management, the AZS blocks should hold more than 8 years. usually it is the other parts that fails first in the furnace, such as regenerators, melter crown,etc.. So the AZS blocks are usually not a major concern for campaign life except for those quick wear areas such as throat and doghouse corners, where a higher grade material could be considered like Iso-pressed chrome or zircon,etc..

2. How do you compare the quality of your AZS blocks to those by western manufacturers like Monofrax, SEPR,etc..?

the quality is very very similar if not the same. Many customers who had previously used European products are now coming to us for the AZS products, because of our good quality, quick delivery time, competitive prices,
