Good Plasticity AZS Ramming Mass

Product introduction of AZS ramming mass

Refractory AZS ramming material is uncertain zirconium refractory material. The key of AZS ramming material is to pulverize the original brick, containing about 20% glass phase. The existence of glass phase in the electromelted AZS ramming material makes it become a strain material after more than 800℃. The plasticity and adhesion of the material in the temperature range of 800~1300℃ is conducive to the sealing of the joint under some conditions with weak displacement

Features of AZS ramming mass

AZS ramming material has the characteristics of high density, good chemical stability, good thermal stability and good plasticity.
