Research on the Effects of the Refining Treatment to the Properties of Dual-Phase Wear-Resistant Steel

Abstract:

Using refining agent to proceed refining treatment on dual-phase wear-resistant steel, the refining agent is made up of CaO, CaF2, Al2O3, Al, Na2CO3 and BaCO3. The experimental furnace is 25kg vacuum induction furnace, stalling 10 minutes after adding the refining agent, the heating temperature is between 1550 and 1600°C. By doing this, the content of harmful impurities including O, N and S in the steel is significantly reduced and the mainly existing form of the main non-metallic inclusions is changed, it also reduces the size and number of the microstructure of the inclusions in the steel and improves the impact toughness and elongation of dual-phase wear-resistant steel significantly.
