Cooling Capacity Evolution of Steel Strip during Oscillatory Feeding Process in Slab Continuous Casting

“…The use of strip is a technique employed to decrease the temperature of molten steel and facilitate solidification in the vicinity, owing to the melting of strip and molten/shedded-strip flow. [17,18,[26][27][28][29] The liquid fractions on the typical slice with different oscillation frequencies are shown in Figure 5. After strip is fed, cooled strip absorbs superheat of surrounding molten steel.…”

“…[8,9,[11][12][13][14][15][16] In comparison, numerical simulation is a crucial tool for obtaining a deeper and more indirect understanding of the distribution of multiphysical fields. [19][20][21][22][23][24][25] Until now, only an extremely limited number of numerical models have been developed to study the multiphysical field during the FST process, [17,18,[26][27][28][29] and these models have been used to investigate the effects of strip feeding speed, [17,18,[26][27][28][29] strip size, [18] and molten steel superheat [18] on the temperature reduction after feeding strip during continuous casting process. However, there are a lack of numerical models that consider strip oscillation during the feeding process to investigate the effect of oscillation on cooling capacity of strip in continuous casting.…”

Recent advances in inclusions and central segregation control technology in tyre cord steel and saw wire steel

“…Many studies on improving the solidification structure of a continuous casting slab of cord steel [77][78][79][80][81][82]. However, there are still many unsolved problems in the continuous casting mould feeding technology, and there is no relevant report on its application in cord steel and saw wire steel.…”

A Novel Model to Predict Shape Variation of Steel Strip During Feeding in Slab Continuous Casting

“…Typically, the process parameters, including the strip feeding speed, strip oscillation frequency, strip amplitude, molten steel superheat, strip width, and strip thickness, are optimized in order to effectively regulate the strip shape during the actual FST production. [1] To date, research on strip shape during the FST process has only primarily centered around investigating the impact of specific process parameters, including strip feeding speed, [12,14,15] strip thickness, [12][13][14] and molten steel superheat, [12][13][14] on the variations in the thickness of the nonoscillatory strip. There are currently a lack of comprehensive studies regarding the influence of various process parameters on the strip feeding depth and the maximum cross-sectional area of steel sheath.…”
