SynopsisAlthough the slag, which is secondary product of steel production, has become to be utilized in many ways, the ratio of utilizing reducing slag produced from electric arc furnace is still low because of its swelling character, for instance. To utilize reducing slag produced from electric
The expansion of electric furnace reducing slag is delayed by its complex hydration. Before using the slag, it is necessary to stabilize the expansion property. Currently the reducing slag is used after aging for stabilization of expansion and judging its stability by the expansion ratio based on the standard expansion test results. Because of delayed expansion, a long time of aging or expansion test is required and then it is unable to judge exactly the degree of stabilization for expansion. In this report, a rapid stabilization method and an expansion test method using steam for reducing slag are presented on basis of some experimental results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
