Numerical simulations are performed to investigate the effect of the SFPB on the liquid steel flow in the tundish and nozzle in comparison with that in a conventional tundish. The results indicate that the SFPB can reduce the dead volume fraction, increase the mixed flow volume with low risk of slag entrapment in the tundish, and generate a swirling flow in the nozzle. As the distance from the nozzle inlet increases, the swirling velocity decreases and the static pressure in the nozzle section increases. A higher velocity and static pressure are recorded in the near-wall region at the upper part of the nozzle, where the turbulent kinetic energy decreases significantly from 0.037 m2 s−2 in a conventional tundish nozzle to 0.013 m2 s−2 in the proposed SFPB tundish..KEYWORDS: Swirling flowtundishnozzlewall shear stresspocket brick‌residence time distributionnumerical simulationcontinuous casting Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by National Natural Science Foundation of China [grant numbers 51974213, 51874215].","PeriodicalId":14753,"journal":{"name":"Ironmaking & Steelmaking","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135854805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, for the upper part of the meniscus, the effect of radiation is considered as a heat flux profile with an exponential function. Subsequently, the thermo-mechanical analysis is conducted by applying the thermal load, as a temperature distribution, on the corresponding finite element (FE) model.

During the melting process, the volatilization ratio was measured, and the volatile compounds were collected with some conductive tapes. Thermogravimetric analysis was conducted to clarify the volatilization of CaCl2-containing slags, and the volatilization ratio was also calculated by the thermodynamic software HSC. It was found that volatilization takes place in both CaCl2-containing and CaF2-containing BOF slags, but their influential mechanisms are different. FeCl2 is the main volatile compound in CaCl2-containing BOF slags. The increasing contents of CaCl2 and FeO in these slags are favourable for volatilization, while higher slag basicity plays the opposite role. In the case of CaF2-containing BOF slags, the volatilization compounds have little relation to the FeO content in the slags, and the volatilization ratio is smaller than that of CaCl2-containing BOF slag.","PeriodicalId":14753,"journal":{"name":"Ironmaking & Steelmaking","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45713153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The open eye area and slag entrapment depth in the double blow plug arrangement are smaller than that in the single blow plug arrangement. In general, the ladle refining effect is better when the blow plug is arranged at 0.4R position and the angle between the two blow plugs is 120°.

Numerical simulations with developed FEA model considered Young's modulus variation and RF tests are conducted to explain the origin of end flare with residual stresses. It's found that the overlap of bending moment caused by residual longitudinal stress and twisting moment caused by residual shear stress in transversal-longitudinal direction leads to opening deformation in front end and back end for hat channel steel. End flare will decrease with the increase of flange length and increase with the increase of material strength. The effect of forming parameters on end flare is analysed that end flare can be reduced with UDT-type (USTB-Durable T) method, constant-arc-length method and appropriate forming parameters. The findings are applied to control end flare of hat channel steel in actual RF process to meet high-precision requirements.","PeriodicalId":14753,"journal":{"name":"Ironmaking & Steelmaking","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49415380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
