Stopper Refractory Sleeve Brick

Stopper Refractory Sleeve Brick

Introduction

1.Made by bauxite clinker and binder through Crushing,Mixing,Shaping,Drying and high temperature Sintering.

2.Al2O3 content is 48%-80%.

3.Main mineral components are corundum and mullite phases.

4.Refractoriness is usually above 1770℃,refractoriness under load is 1420-1550℃.It is a neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion.

5.Working temperature:1350℃ -1650℃.
