deoxidation with zr

Influence of compound deoxidation of steel with Al, Zr ,Nitride Precipitation on Particles in Fe-10 mass % Ni

Influence of compound deoxidation of steel with Al, Zr, rare earth metals, and Ti on properties of heavy castings , Deoxidation was thermodynamically analyzed at presence of the mentioned elements For particular conditions a probable course of deoxidation was estimated at test castings , Archives of Foundry Engineering Rocznik .The total number of particles above 01 mu m remains almost constant except in Ti deoxidation, but the proportion of cubic particles which correspond to nitrides and oxide-nitrides increases during holding at degrees C in Ti, Zr, Ti/Mg and Ti/Zr deoxidations.

Electrochemical Deoxidation of Solid Zirconium Dioxide in ,DE-OXIDATION OF PK942 STEEL WITH Ti AND Zr

deoxidation An analysis of the experimental results showed that the poor electrical conductivity of the intermediate compound, CaZrO 3 and its blocky morphology inhibited the electro-deoxidation process The increase in the sintering temperature of the pellet made it better conductinginclusions, the addition of Zr also had a great effect on the size distribution and the number of non-metallic inclusions The result of the Zr addition was a large reduction in the total non-metallic inclusion surface area The additions of both titanium and zirconium had similar effects to the addition of Zr.

Deoxidization

Deoxidation is important in the steelmaking process as oxygen is often detrimental to the quality of steel produced Deoxidization is mainly achieved by adding a separate chemical species to neutralize the effects of oxygen or by directly removing the oxygen , D is the deoxidizing agent, and O is oxygen .STEELS AND CAST IRONS are basically alloys of iron and various other elements in the periodic table The vast majority of , Usually minimized in steel by deoxidation with aluminum and/or silicon and vacuum degassing Hydrogen (H) Undesirable in steel If entrapped, can cause crack formation , (Zr) Added to steel for sulfide shape control.
