Deoxidization is a method used in metallurgy to remove the oxygen content during steel manufacturing. In contrast, antioxidants are used for stabilization, such as in the storage of food. The procedure involves adding materials with a high affinity for oxygen, the oxides of which are either gaseous or readily form slags. Deoxidation is the removal of excess oxygen from molten metal.
If at the end of the . Sources of oxygen in steel. Kinetics of deoxidation. Key Words: deoxidation , killed steel, steelmaking. Refining of hot metal to steel is done under oxidizing atmosphere. Englisch-Deutsch Wörterbuch und viele weitere Deutsch-Übersetzungen.
During refining oxygen . Both blowholes and inclusions adversely affect the steel quality. In order to prevent oxidizing of steel components during solidification the oxygen content should be reduced. The oxygen content in iron varies inversely with the impurity contents, .

LEOs Englisch ⇔ Deutsch Wörterbuch. Mit Flexionstabellen, Aussprache und vielem mehr. Thus, some type of deoxidation process is required.
In addition, proper deoxidation of all melts enhances fluidity and therefore castability. Of course, deliberate oxidation treatments (the oxidation- deoxidation process previously described) are still employed. These are designed to preclude hydrogen pickup in copper alloy . Departamento de Engenharia Química e de Materiais, Pontifícia Universidade Católica do Rio de Janeiro – PUC-Rio, Rio de Janeiro, RJ, Brazil. LIQUID IRON DEOXIDATION BY ALUMINUA BRIEF REVIEW OF.
EXPERIMENTAL DATA AND THERMODYNAMIC DESCRIPTION. André Luiz Vasconcellos da Costa e . CO pressure is established at the vacuum-melting temperatures even at low oxygen contents, oxygen is removable by carbon deoxidation. Here again, to estimate the feasibility of carbon deoxidation , the thermodynamic parameters γc and γo must be known.
Data are not available currently for the . Dissolved associate MmOn was used to describe the interaction between dissolved M and dissolved oxygen instead of the interaction parameter of Wagner. The deoxidation equilibrium of liquid steel was investigated from a new perspective. The concentration of unassociated oxygen could be considered as the activity of . Solution Consider deoxidation by Si (Eq. 7).
C (Appendix ), WSi = 0. Assuming the deoxidation product as MnO-SiOand using Figure 5. SiOin the deoxidation product is , and therefore, MnO content is. The process of removing oxygen from molten steel through the use of a suitable chemical agent, such as aluminum or silicon. This removal is one of the steps in the steelmaking process.
