In this article, a coupled three‐dimensional mathematic model is established to describe electromagnetic field, fluid flow, heat transfer and solidification in round bloom continuous casting mold with stirring (M‐EMS). The interaction between the induced flow impinging jet from straight‐through submerged entry nozzle (SEN) of caster numerically analyzed. results show that force appears be circinate at cross section bloom. Moreover, melt characterized by dominant swirling movement along...
Ni-Co-B coating was electrodeposited in sulfate bath with dimethylamine borane (DMAB) as reducing agent. The experiment explored the effect of DMAB concentration (CDMAB, 1∼10 g/L), current density (Jk, 2∼8 A/dm2), temperature (Tbath, 30∼60 °C) on morphology and hardness, determined best parameters: CDMAB= 8 g/L, Tbath=60 °C, Jk=4 A/dm2. average hardness crack-free is 818 HV, B content about 2 wt.%. In order to develop a stress-relieving heat treatment scheme, effects temperatures (100∼500...
The hydrogen concentration in steel is directly related to the embrittlement (HE) sensitivity of steel. This study combined electrochemical charging, slow strain rate test (SSRT), and permeation experiments investigate variation pipeline with hydrogen-charging time. influence on mechanical properties X80 was obtained, ultimately, a quantitative relationship between established. results show that gradually increased time formula can be given as CH = 5.35 − 4.2 exp (−0.26t); HE index...
Abstract In this paper, a compensation control model of secondary cooling process billet continuous casting for quality steel has been presented. The effects on the spray various parameters such as superheat, speed, water temperature and chemical component were considered. determined to associate with two‐dimensional heat transfer equation solved by finite‐difference method. Effects superheat surface temperature, solidification structure solidifying end point discussed. Results indicate that...
In the current paper, a kinetic model was developed to study entrapment of inclusions in molten steel flowing through Submerged Entry Nozzle (SEN) during billet continuous casting process. The trajectory calculated by considering drag force, lift force and gravitational force. locations on SEN wall were predicted. effects nozzle diameter, speed, dimension, inclusion diameter clogging quantitatively discussed. results indicate with larger than 100 μm are not able be entrapped wall;...
Abstract In the current paper, Methods of enlarging area for distribution segregation solutes were introduced to mitigate center macro‐segregation in steel billets and slabs during continuous casting process, which cost less have significant effect. The location is relative shape liquid‐core at solidification end casting. A method dissymmetrical cooling on different surfaces, by precipitation was enlarged, process. Method optimizing uniformity solidified shell transverse direction slabs....
