Behaviour of oxide inclusions and sulphur in ‘two-stage basicity control’ refining method of Si-killed spring steel
TL;DR: In this paper, a two-stage basicity control method was carried out that high basicity (R < 1.5) top slag was used in the LF refining and then low basicity(R < 0.8 − 1.0, Al2O3 < 0, 6%) top slags was used.

TL;DR: A spring steel austenite grain display method is described in this paper, which consists of the following steps: (1) putting a sample at 850-900 DEG C, preserving heat for 10-40 minutes, quenching at a completely hardened cooling speed, tempering the cooled sample at 400-600 DEGC, and performing aircooling to room temperature; (2) cutting and embedding the cross section of the quenched sample in the rolling direction, and finally performing polishing.
