Coordinating optimisation of F-EMS and soft reduction during bloom continuous casting process for special steel

Abstract: To control the halfway cracks and shrinkage cavities during bloom continuous casting (CC) process, final electromagnetic stirring (F-EMS) and soft reduction techniques have been coordinately optimised. The halfway crack and shrinkage cavity can be successfully controlled by adopting the CC technique parameters described as follows: (1) casting speed is 0.62 m min-1, (2) secondary cooling water ratio is 0.2 L kg −1 , (3) reduction amount is 18 mm; (4) reduction region ranges from 19.9 m (location of M3 roller) … Show more

“…Moreover, the stress applied during the secondary cooling process causes a slight deformation of the casting, causing tensile stress on the surface of the casting and resulting in cracks. To control the initiation and propagation of cracks during casting, numerous researchers have optimized continuous casting process parameters, including superheating [18], casting speed [19,20], electromagnetic stirring [21,22], soft reduction [23,24], and coordinated control technology involving electromagnetic stirring and soft reduction [25]. Electromagnetic stirring has a significant impact on solidification segregation.…”

“…During solidification, macrosegregation mainly caused by the thermal contraction of the outer solidified shell is a serious internal defect due to the large size of mushy zone, [3] and damages the efficiency of final products. [4] The final electromagnetic stirring (EMS) [5,6] and soft reduction (SR) [7][8][9][10] are efficient technologies to control macrosegregation and shrinkage defects. The previous research reports have investigated internal defects formation during rolling process to enhance the efficiency of cast products.…”

“…These defects were not eliminated absolutely by the subsequent heating and rolling, which can seriously affect the product performance [3][4][5]. The soft reduction technique [6][7][8][9] can compensate for the solidification shrinkage at the solidification end, squeeze out the solute-enriched liquid in the mushy zone, improve the flow property in the billet centre and reduce the internal defects of the billet [10,11].…”
