Dolomite crude is applied to roasting in furnaces and the subsequent application at steel melt in convectors. It’s issued in the form of fractions: 5-20 mm, 20-40 mm, 40-80 mm.
Technical description of a raw dolomite:
Grain structure, an admissible mass fraction of pieces below the bottom limit, no more, than % | 10 |
Grain structure, admissible mass fraction of pieces above the top limit, no more, than % | 10 |
Mass fraction MgO2 of %, not less | 19 |
Mass fraction SiO2 of %, no more | 3 |
Mass fraction Al2O3 + Fe2O3, % no more | 1,5 |
The annual volume of output makes approximately 200 thousand tons.
Dolomite crude for the metallurgical industries is issued on standard of Belarus 300200623.007-2005.
