Establishing the Optimum Composition of Superaluminous Refractory Products, Used for Steel Ladle Bubbling

Abstract:

It is widely acknowledged by all specialists in the field of ferrous metallurgy that the porous peg of the kit for injecting inert gases into the steel casting ladle is the weakness of the entire assembly. This is the most prompted piece due to the thermal shocks that occur when injecting cold gas and the wear and tear and corrosion caused by disturbances in the steel during the injection process. The porous structure of the peg considerably weakens the physical properties and widens the surface of metal - refractory material contact thus enabling the destructive chemical action. In addition, the process of injecting oxygen for cleaning the metal peg also contributes to the destructive action and the substantial decline in its endurance. All these considered, it has been decided that the material for producing these items should contain at least 95% Al2O3 which means using only tabular alumina. As far as the binder is concerned, it has been established that a liquid chemical binder made of colloidal alumina should be used since this does not considerably diminish the Al2O3 content of the end product. It is the aim of this paper to bring forward the author’s research regarding the production of the porous plug using high-alumina refractory materials.
