Composite refractory brick

Introduction

Composite refractory brick refers to those bricks which have both a dense part and a insulating part. The working surface is the dense part and retains the properties of refractory bricks. The backside is embedded with a thermal-insulating material, which can effectively prevent thermal loss and lower the temperature of the kiln shell. Its dense part can be made from various raw materials. Depending on the working environment it is in, different manufacturers usually have different solutions.

Characteristic

1. Low thermal conductivity, high insulation ability
       2. Protect the equipment, hlep the equipment longer life span
       3. Without asbestine, safe and clean
       4. Good durability, can withstand continuous thermal burden under high temperature

Application

Safety zone in cement rotary kiln
