Product detail:

  Supply  high refractoriness furnace bricks at lowest price 

 

Introduction

The  furnace bricks  are used as the main raw material alumina hollow ball, high performance Micropowder for additives, organic material temporary binder high temperature shuttle kiln baked.

 

furnace bricks  Characteristized:

1. containing a large number of closed pores

2. have a lightweight high temperature

3. good insulation properties

4. refiring small contraction

5. excellent thermal shock resistance

7. strong resistance to the corrosive gas and slag.

 

  furnace bricks  can greatly improve the thermal efficiency of the kiln to shorten the production cycle, reduce the kiln body weight to achieve energy saving.
