During the conventional continuous casting process of high-aluminum steels(w([Al])>0.5 wt.%),some components of slag,such as SiO2,B2O3,and TiO2,could be reduced by aluminum in molten steel.Therefore,the CaO-BaO-Al2O3-CaF2-Li2O non-reactive mold fluxes wer
In steel continuous casting(CC),the choice of the appropriate speed at which the slab is cast can be influenced by many different factors and phenomena.While the slab thickness seems to have the biggest impact,other features like the slab width have been
Based on the principle of speed superposition,the oscillation system for continuous casting mold synchronously driven by double servomotors can adjust all parameters online with high reliability and high bearing capacity.The elastodynamic model of the osc

The influence of cooling rate on microstructural evolution and precipitation behavior in Ti,Ti-Nb and Ti-Mo low-carbon steels during the continuous cooling process was studied by dilatometer method,optical microscopy,and transmission electron microscopy.T
Pulse magneto-oscillation(PMO)added during solidification could affect the solidification structure and macrosegregation.A modified thermal simulation equipment was applied to prepare GCr15 bearing steel continuous casting billets with different PMO peak
A funnel-type mold is commonly used to provide necessary clearance for the submerged entry nozzle in the thin slab casting(TSC).The partially solidified shell is subjected to the mechanical deformations,which can lead to the defects formation and,as a res
The effect of mold electromagnetic stirring(M-EMS)on the solidification structure and solute segregation in the con-tinuous casting bloom of U78CrV steel is investigated.The solute distribution in the macroscale is analyzed using a carbon-sulfur analyzer
通过在聚乳酸(PLA)和聚丙烯(PP)共混体系中分别引入马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH)和甲基丙烯酸缩水甘油酯接枝乙烯-辛烯共聚物(POE-g-GMA),制备出具有不同结构及性能的共混材料(PLA/PP/POE-g-MAH,PLA/PP/POE-g-GMA),并采用转矩流变仪、扫描电子显微镜、差示扫描量热仪、平板流变仪及电子万能试验机等研究了不同界面增容剂的结构对PLA/PP共混体系界面状态及性能的影响.结果表明,POE-g-MAH和POE-g-GMA均可改善PLA与PP的相界面形态,但
