Application of new end-deoxidizer on converter;

After deoxidizing in refining furnace by Al final deoxidizer and Al-Si-Ca-Ba compound deoxidizer respectively,impacting experiment at low temperature for common C grade steel casting was carried out,and the distribution and morphology of inclusions were analyzed using optical microscope and scanning electron microscope.

The steel liquid deoxidation eventually is an important craft operation process when casting steels melting using arc furnace,is also important technique measure that affects the cast steels metallurgy quality.

Influence of Deoxidizer on Mechanical Property of Deposited Metal of Electrode;

Advance of research on gas purification deoxidizer;

Packing with material of low venting quality and adding deoxidant were applied to inhibit rancidification of stir-fired sunflower seed during storage.

The result indicated that the Al - Mn- Fe alloy deoxidant can increase utilization ration of aluminum, decrease content of oxygen and nitrogen and inclusion in the steel.

Compared with the control, the vacuum package or adding deoxidant package with materials of low venting quality can constrain the accelerating speed of PV and AV, and delay rancidity.
