Composition of iron oxide scale
In the process of steel forging and hot rolling, due to the reaction between steel and oxygen in the air, a large number of iron scales are often formed, resulting in the accumulation and waste of resources. If these resources are used reasonably, the production cost can be reduced, and at the same time, it can play the role of environmental protection and energy saving. The main components of mill scale are Fe2O3, Fe3O4 and FeO. Among them, the outermost layer of the oxide scale is Fe2O3, accounting for about 10% of the thickness of the oxide scale to prevent oxidation; The middle is Fe3O4, about 50%, and the innermost contact with iron is FeO, about 40%.
Generally, there are three layers of scale: the outermost layer is Fe2O3? , accounting for about 10% of the whole thickness of mill scale, its properties are: thin and shiny, brittle and easy to fall off; And has the function of preventing the interior from continuing violent oxidation; The second layer is a mixture of Fe2O3 and FeO, usually written as Fe3O4, accounting for about 50% of the total thickness; The third layer connected with the metal body is FeO, which accounts for about 40% of the thickness of the scale? FeO is sticky in nature, and it is not easy to remove when it sticks to steel.
There are many manufacturers of iron oxide, and most of them run other products related to iron oxide, because it is very beneficial for iron oxide to run these products concurrently. In addition, the composition of mill scale is quite complicated, and the formation of mill scale will take some time. After reading the information about mill scale introduced by Bian Xiao, everyone will have a preliminary understanding of mill scale more or less, and even touch the class!
