What are the benefits of using active lime?
Lime calcined in a rotary kiln or a new shaft kiln (sleeve kiln) at a temperature of 1050-1150 ° C, which has high volume density, high porosity, high specific surface area and fine grain size. Lime is called active lime, also known as soft burnt lime.
What is the role of adding Nb, V, Ti elements to the steel for microalloying?
The result is a reduction in carbon equivalent, a significant increase in the strength and toughness of the steel, and a significant cost advantage.
Does slag oxidation have an impact on the smelting process?
affecting dephosphorization and desulfurization, is conducive to dephosphorization, is not conducive to desulfurization.
Basic factors that affect the dephosphorization effect of the converter
Influence of alkalinity of slag: Increasing alkalinity can improve dephosphorization capacity, but too high alkalinity affects the viscosity of slag and is not conducive to dephosphorization.
Analyze the favorable conditions for the P-reaction
However, when the temperature is too low, the slag cannot be formed and has no fluidity. Therefore, favorable conditions for removing P are high alkalinity, high (FeO), large slag amount, and appropriate low temperature.
Why is phosphorus regenerated in tapping?
In the converter, the removal of phosphorus is relatively sufficient, because the conditions are favorable, the alkalinity is high, the (FeO) content is high, the slag amount is large, and the slag fluidity is good, but in the tapping, with the addition of the deoxidizer.
