Which of the following oxide(s) of iron would be obtained on prolonged reaction of iron with steam? While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and … Using the commercial software … These oxides interact with one another in the kiln at high temperature to form more complex compounds. Alumina, Calcium Aluminate and silicon-based Ladle Slag Conditioners are designed to quickly assimilate into the entire ladle slag volume. Melting temperatures vary between 1200 deg C to 1400 deg C. Chemical characteristics of the slag is determined by its composition and accordingly it can be either acidic or basic. Slags having higher CaO content are basic while slags with high SiO2 content are acidic. The limestone also decomposes to CaO which removes the silicate impurity of the ore in the form of Slag. 3.
