Product Description

       FC  magnesite carbon whole tap hole  bricks for bof 

 

  Manufacture:

 

     1. Use the 99% Large crystal as the main raw material , it can make the bricks’

 

 structure  dense , with the strong resistance for washing and errosion ,and then prove 

 

the refractoriness ,strengthen the resistance from the slag  

 

          At the same time we add 599 flake graphite as binder, this kind of large Phosphate

 

 tablets  can improve the ability of resisting oxidizing .

 

     2.We import CaB6 and use this kind of material as the additive, which can refine 

 

the resistance of oxidizing obviously;                 

                 

    3.Mix the raw material above and other ones together evenly 

 

   4.Forming by isostatic pressing machine and dry under high temperature .

 

products feature:

     

 

1.Convenient for changing and construct  

 

2.Eliminate the steel water leaking  from tap hole , improve the safe ratio apparently. 

 

3.deduct the oxidizing secondly for the steel water , raise the quality of the steel water. 

 

4.much longer service life( 200 times on converter continue working 25 hours) 

 

5 Perfect thermal shock ability ,can resist the extreme cold and hot  

 

6.Dense structure ,high resistance for washing and erosion , 

 

7..excellent resistance for oxidizing slag and spalling ; 

 

8.high refractoriness;  

 

9.Wonderful sinter ability, and adhesion

 

 

Product application:


 apply to the steel  water pouring out for BOF and electric arc furnace
