Dear colleague, you must avoid high FeO content into the slag, it means that you have high [o] into the steel. I dont know what type of deoxidizer you use Al, Si or SiCa,
but adding of Feo into the slag will decrease content of these elements in the steel. Al203 will bock FNC nozles and you will...
For the basic lining MgO slags are usefull, but it depend also what steel are you cast (carbon content), if you are casting special steels, the cover slag needs to has and chemical activity in order to catch non-metallic inclusions.
Between 1950 and 1980 it was a lot of research investigations in physical chemistry in high temperature proceses and technology done by soviet scientists. They made a lot of basic studies in ironmaking and steelmaking.In Bulgaria we was studing metallurgy from the books of Bardin, Javoisky...
Vacuum degassing gives opportunity to use technology "vacuum carbon deoxidation" - it means more clean steel, because the product of deoxidation is CO instead of Al2O3 or SiO2. The adding of Al and FeSi is only to cover needings required to the steelgrade. Also content of hydrogen is less than...
Wanadium give opportunities to have fine gralinsize. It impruve elongation avd impact strength. If you dont make normalising rolling, you need normalising threatment.
You can use ferrovanadiun 80%.
1. You must calcilate gas or other fuel consumption per each steel grade or groups of similar steel grades.
2. Yoy must know what is the consumtion of the refractories per ton steel.
3. You must know what is the consumtion of the watter for cooling.Uou must know what is the consumption of the...
The induction furnace can't refine steel - decrease [C] and [P] content. Induction stirring don't give opportunity for good metall-slag reactions for deep desulphurisation.After melting in the induction furnace it need additional refining treatment into the laddle with Ar stirring and new slag...
Steel cartriges are produced from steel grades similar to SAE 1006, 1008 or 1010 ( suitable for deep drawing ) with copper or other cover for rust protection.
