A multi-model integrated prediction framework for FeO content during the iron ore sintering process was presented. By applying the affinity propagation clustering algorithm, different working conditions were efficiently classified and the support vector machine algorithm was utilized to identify these conditions. Comparison of several models under different working conditions was carried out. The regression prediction model characterized by high precision and robust stability was selected. The model was integrated into the comprehensive multi-model framework. The precision, reliability and credibility of the model were validated through actual production data, yielding an impressive accuracy of 94.57% and a minimal absolute error of 0.13 in FeO content prediction. The real-time prediction of FeO content provided excellent guidance for on-site sinter production.","PeriodicalId":16151,"journal":{"name":"Journal of Iron and Steel Research International","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141253053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on this, the new type of mold flux for La-bearing FeCrAl alloy continuous casting was designed and its basic properties were evaluated. The results showed that the order of reaction degree of fluxing agents in CaO–Al2O3–La2O3-based slags is (Na2O) > (B2O3) > (Li2O), and the percentages of mass change of fluxing agents were 85.8, 54.29 and 42.35 wt.%, respectively. Moreover, the addition of (Li2O) and (Na2O) promoted the reaction between (CaO) and [Al], and the reaction degree of the former was weaker than that of the latter, which was due to the greater effect of (Na2O) on the activity of (CaO) and (Al2O3) than (Li2O). Compared with the reactivity of CaO–SiO2-based slags, the percentages of mass change of Al and La caused by slag–steel reaction decreased by 10.63–14.36 and 39.78–50.49 wt.%, respectively. The percentages of mass change of (Al2O3), (La2O3) and (CaO) in slags highest increased by 17.71, 17.98, and 7.81 wt.%, respectively. The reactivity of CaO–Al2O3–La2O3-based slags was significantly weakened. Ultimately, the new type of mold flux was designed and the composition range was determined.

Also, the structural properties of the slag were characterized by Fourier transform infrared spectroscopy. The concept of “a ring structure of Ti–O–Si” was proposed to express the change in the viscosity of the blast furnace slag. The results showed that the viscosity of slag increased with the increase in BaO content while the potassium removal capacity decreased. Furthermore, an increase in TiO2 content from 2 to 20 wt.% resulted in a decrease in viscosity and an increase in potassium removal capacity. The Fourier transform infrared spectroscopy results showed that the charge compensation of Ba2+ can form complex aluminosilicate structure and increase the viscosity of slag.

The non-isothermal crystallization kinetics of the SFC system were investigated using differential scanning calorimetry. The crystallization process of SFC was studied under different cooling rates (5, 10, 15, and 20 K/min), and the crystalline phases and microstructures of the SFC crystals were verified through X-ray diffraction and scanning electron microscopy. The results indicate that when the SiO2 content is 2 wt.%, increasing the cooling rate promotes the precipitation of CaFe2O4 (CF) in the SFC system, thereby inhibiting the precipitation of Ca2Fe2O5 (C2F). In contrast to the CaO–Fe2O3 (C–F) system, the addition of SiO2 does not alter the precipitation mechanisms of C2F and CF. By further adding SiO2, the precipitation of Ca2SiO4 (C2S) significantly increases. Simultaneously, the CaO content in the liquid phase decreases. This leads to the crystallization process of the CF4S (4 wt.% SiO2) system bypassing the precipitation of C2F and directly forming CF and CaFe4O7 (CF2). In the case of the CF8S (8 wt.% SiO2) system, the crystallization process skips the precipitation of C2F and CF, directly yielding CF2. The crystallization process of both CF2S (2 wt.% SiO2) and CF is similar, comprising two reaction stages. The Ozawa method was used to calculate the activation energy for the crystallization of C2F and CF as − 329 and − 419 kJ/mol, respectively.

A two-step method of gas-based direct reduction and magnetic separation was thus proposed to recover iron and reduce phosphorus. The results showed that the powdery reduced iron produced contained 92.31% iron and 0.1% phosphorus, and the iron recovery was 92.65% under optimum reduction condition, which is suitable for following steelmaking. The apatite will be reduced under long reduction time and a large reducing gas flow rate, resulting in more phosphorus found in the metallic iron.

A systematic study was conducted to evaluate the high-temperature corrosion behavior of this coating, and its resistance to corrosion at high temperatures was scientifically assessed. The results indicate that the thickness of Fe–Cr–Mo amorphous coating is approximately 350 μm, exhibiting typical amorphous characteristics as confirmed by X-ray diffraction and transmission electron microscope characterization. During each stage of the 750 °C corrosion test, the oxygen content of the amorphous coating was significantly lower than that of the contrast coating (PS45 alloy coating), indicating a superior corrosion protection effect at high temperature. After 100 h of continuous testing, the corrosion mass gain of the amorphous coating was only 28.62% that of PS45 coating and 3.89% that of T12 steel substrate, indicating significantly depressed high-temperature corrosion kinetics. The excellent high-temperature corrosion resistance of Fe–Cr–Mo amorphous coating is primarily attributed to the stable Fe/Cr oxide film generated by the metastable state of the amorphous state, which serves as an excellent barrier. Furthermore, under the influence of heat in a high-temperature environment, the amorphous structure gradually transforms into a nanocrystalline structure. In contrast, the oxide film of the amorphous/nanocrystalline coating has low thermal stress, leading to better adhesion with the coating and resistance to cracking and peeling, thus providing excellent sustained protection.","PeriodicalId":16151,"journal":{"name":"Journal of Iron and Steel Research International","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141197328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
