The definition, formation and composition of minerals

Aluminum high iron ore market, a large cornucopia of resources and cost advantages in contrast. Success within this resolution, are sintered at high iron ore of aluminum, according to the welding process and solve problems from the slag phase in all fairness clean, providing a line reaching the body weight of molten alumina ininduction 80 kg / m ~ 1970 normal font.

For a strong negative impact of aluminum, iron ore and steel in the structure in the load and justifiable dairy group made these progress monitoring: calcite grinding machine

(1) improve the content of FeO sinter charge built about 8% FeO content of iron ore, which happens to be more than 10% rolling around in its industry, especially on the volume of acid control FeO sinter to 12% to 14%. The increase in FeO content of sinter sintering temperature, while improving fuel economy, increase in the blast furnace, and also effectively control the need for low temperature sintering rates. Practice implies that your production increase of 5%, fuel RDI, that 1% growth, gives 1.5%. Thus, steel blast furnaces into consideration to update the index, achieved top notch performance.

(2) Adjusting blast furnace slag of magnesium oxide (MgO style) the upkeep, control of blast furnace slag style MgO Al2O3: = 0,65 ~ 0,8, alkalinity ternary R 3 = 1.50 + 0.05, alkalinity four yuan R4 = 0.95 + 0.05, the slag is affordable to phase composition, providing liquidity for the slag. Simultaneously, the empowerment of desulphurization slag.

(3) improve the physical warmth. With increasing Al2O3 content of slag while in the melting temperature of slag increases, not surprisingly, be of use for blast furnace hearth, heat accumulation for your molten iron Thermophysics, T = 15 + 20 ℃, increase the liquidity of iron slag.mining projects case

(4) boost the amount of melting slag control sintering Al2O3 / SiO2 ratio. Sintered Al2O3, contained in the improvement consider necessary and also to enhance the content and stability of SiO2 slag. Generally high in the aluminum smelting furnace blast of iron ore experience, control over Al2O3 / SiO 2 in 0,1 ~ 30k to be sure the quality of sintering, including Al2O3 / Al2O3 SiO2 content up has grown, the sintering forms the trunk of vitreous easy agglomeration forces back straight. Daily while in the blast furnace melting steel slag Al2O3 / SiO2 ratio was noted at 0.5 ~ 0.6, are not able to always match the operation of blast furnace, to get good performance. coal crushing and screening plant

(5) view the content of Al2O3 inside the milk of several measures of treatment suitable for the culmination in the merger, low price base: Omega (Al2O3) = 15% ~ 17% binary ternary slag a control, 05 ~ 1.15, basicity, around four yuan basicity basicity 1 , 50 0,92 Al2O3 around style MgO / ~ 0,70 to 0.65, temperature control 0,40% cyclooctene can promise the physical integrity of hot ℃ across the melting smooth 148.
