Abstract

Basic oxygen furnace (BOF) dust is a kind of solid waste in the metallurgical steelmaking process, which contains more than 50 pct total iron and a certain amount of overburned MgO and CaO. Based on the nonhydraulic cementitious property of MgO in BOF dust, MgCl2 is added together as a binder to prepare cold-bonded pellets returning to BOF, which is the most economical route to recycle secondary resources. In this study, we investigated the hydration and crystallization behavior of MgO-based binder prepared by MgO superheated at 1500 °C and MgCl2 in cold-bonded BOF dust pellets, to solve the problem of whether the overburned MgO can be hydrated with MgCl2 to form crystalline phases, and generated nonhydraulic cementitious structure with high strength to consolidate the pellets. The results show that the overburned MgO prepared at 1500 °C and MgCl2 can form adhesive gels to absorb BOF dust particles by hydration reaction. The gels develop to 5Mg(OH)2·MgCl2·8H2O crystalline phase with a reticular structure after solidification, and the crystalline phase produces pellet mechanical strength by wrapping and connecting bridge. The hydration reaction produced by overburned MgO is incomplete, and the hydration reaction degree is 50 to 65 pct.
