Special Low-creep Clay Refractory Brick

Introduction

Special low-creep clay refractory brick is made of high-quality pyrotechnical refractory raw material with less impurities, compact structure and high purity. It is added with new refractory raw materials, additives and binders. It is formulated by proportion, mixing, high-pressure molding and high-temperature sintering. It has the advantages of small creep rate and strong heat storage capacity.

Special low creep clay refractory brick characteristics:
1. Low creep rate and low temperature creep.
2. High load softening temperature.
3. Good impact resistance.
4.Good hot Crushing Strength
5, high temperature volume stability, good abrasion resi
