Fundamental Study on the Low-Reactive Mold Fluxes for RE-Bearing Heat-Resistant Steel

摘要：

　　Due to the high cerium content(0.03%-0.08%,)and strong reducibility of RE-bearing heat-resistant steel,serious slagmetal interface reactions occurred and it was ubiquitous in the mold when common mold fluxes were used.Composition changes caused by the slag-metal interface reactions could lead to deterioration of the properties of the mold flux and surface defect of the casting billet.Aiming at the composition of RE-bearing heat-resistant steel,a new low-reactive mold flux based the CaO-Al2O3-Li2OCe2O3 slag system was designed and explored,the melting properties,viscous characteristics,tension and crystallization properties of the new mold fluxes were systematically investigated.The composition and properties of the new low-reactive mold flux for RE-bearing heat-resistant steel were determined.The results could provide theoretical basis for the development of mold fluxes for RE-bearing heat-resistant steel.
