Main Composition:SiO2 + Al2O3 Capacity:3000 MT per month Raw Material:Mullite Color:Grey Use Temperature:1350℃

Product Introduction

Mullite castable is mainly made of porous mullite aggregate, and stir into a fine powder and additive. The long term using temperature is 1350℃. It can direct contact with the working lining using flame and achieve high temperature energy saving.

Features

1.Low thermal conductivity. 2.Good heat preservation performance. 3.High mechanical strength.

Application

Mullite castables are used in petrochemical industry tubular heating furnaces, light diesel oil,sulfur recovery devices, steam boilers and pipe insulation floor, other industrial furnace doors, fire holes, observation hole door linings, etc.
