Nitrogen content of the high-pressure bottle steel was high and with big fluctuation, it is difficult to control. SO, investigation on nitrogen content of the all steelmaking process is carried out. Results of the investigation indicated that nitrogen content of the aimed steel was high, nitrogen absorption was mainly happened during tapping and in the course of after refining to before casting. And then nitrogen control measures such as low-nitrogen steel melting technology, optimization of deoxidization, protective casting technology is raised. After that nitrogen content of the aimed steel was reduced and nitrogen absorption during tapping and in the course of after refining to before casting was effectively controlled, nitrogen content of the finished steel was stably controlled in 50×10-6, the effect of nitrogen on property of steel is reduced. © (2014) Trans Tech Publications, Switzerland.

Processes of dealing with vanadium titanium magnetite have been reviewed by three different enterprises, i.e. The New Zealand Steel, Highveld Steel & vanadium Corp Ltd in South Africa and Panzhihua Iron and Steel Corporation in China.A process of rotary kiln direct reduction+EAF smelting DRI+recovering vanadium from vanadium bearing hot metal is adopted by the New Zealand Steel and Highveld Corporation. However, this process only recovers the Fe and V elements in the iron ore, whilst the Ti element in the EAF slag is difficult to extract because of the low grade TiO2. A process of rotary hearth furnace (RHF) direct reduction+EAF deep reduction+vanadium recovery is employed by Panzhihua Iron and Steel Corporation, and there are no other materials except for DRI and reductants that are added into EAF, resulting in above 45% TiO2 content in the slag, which is higher than that of the other corporations. Moreover, the Ti element in the slag could be extracted by the traditional sulfuric acid method. By comparison to the former process, the latter explores a new way to recover the Fe, V and Ti elements in the vanadium titanium magnetite. Furthermore, the direct reduction processes described in this article are constructive for comprehensive recovery of the vanadium titanium magnetite, as well as other similar composite ore resources. © 2015 Taylor & Francis Group, London.

The integration of photocatalytic processes to simultaneously convert plastic waste into valuable chemicals and generate green hydrogen represents a significant advancement in the field of renewable energy and environmental remediation. The study demonstrated the potential of solar-powered photocatalytic processes to convert plastic waste, specifically polylactic acid (PLA), into value-added chemicals like pyruvate while simultaneously producing green hydrogen. The use of a CZS/NiPS 3 heterojunction as a catalyst was pivotal, as it created an efficient interface for electron transfer, enhancing the overall photocatalytic activity. The CZS/NiPS 3 -20 % catalyst exhibited remarkable performance, producing 777.4 mmol/g of hydrogen over 10 h in a pretreated PLA solution. In a real PLA plastic system, the catalyst generated 506.41 mmol/g of hydrogen over the same period, showcasing its practical applicability. The catalyst facilitated the selective photoreforming of PLA into pyruvate, a high-value chemical, as confirmed by GC-MS analysis. This dual functionality-hydrogen production and chemical conversion-maximizes the utilization of photogenerated electrons and holes, improving the overall efficiency of the process. This research offers a strategy to address plastic pollution and boost the hydrogen economy by converting waste into valuable products and using seawater for clean energy.

The nuclear power molten salt reactor of heat storage metal tank and fluid pipe are usually consumed by corrosion in high temperature chlorinated environment, and the structure material thickness design reference for the corrosion rate is critical. This work focused the compatibility study of high Cr-Co-Ni-Si type HR160 superalloy with molten KCl-MgCl2/air corrosion at 700 ? for 4-240 h. By XRD, SEM and OM observation analysis and mass recording curves showed that the corrosion rates curve of HR160 was parabolic in 96 h, the corrosion rate was in the range of 1~2.5 mm/a between 15~63 µm uniform corrosion product layer in 96 h. The mass loss was mainly due to the oxidative chlorination of Cr elements, and the outer shell layer was a porous film structure of MgCr2O4 corrosion products peeled off by the corrosion products with the growth of immersion corrosion time. The second outer uniform corrosion product layer was dominated by Mg2SiO4 and Si oxidation reaction. Low viscosity molten salt through the porous at high temperature, sparse corrosion products layer continues to contact with the substrate uniform corrosion, and the reaction generated by the high mobility of chlorine gas, which penetrate the oxidation layer and the formation of low melting point volatile metal chloride with the alloy. © 2022 SPIE

In order to recover the precious metal elements in vanadium-titanium blast furnace slag, the analytical method that direct determination of the range from 0.001% ∼ 0.300% chromium, cobalt nickel, gallium, niobium, scandium and zirconium in the blast furnace slag of vanadium titanium magnetite by inductively coupled plasma atomic emission spectrometry was established. Sample digestion reagent consists of hydrofluoric acid, hydrochloric acid, nitric acid and sulfuric acid, and their ratio, dosage and reaction control condition are all optimized, so make sure that the blast furnace slag of vanadium titanium magnetite can be quickly completely digested. At the same time, the high content of silicon dioxide can be removed by volatilization to simplify the sample solution matrix composition, and because of the titanium ion and sulfate ion complex reaction generating oxygen titanium sulfate ion so as to solve the high concentration of titanium matrix easy hydrolysis problem in low acidity medium, thus it greatly reduce the acidity of sample solution to reduce the matrix effect. That the influence of the spectral interferences and matrix effects in the high concentrations of titanium, iron, vanadium, aluminum, calcium and magnesium coexistence matrix system had been studied, then the test results are classified summary. The influence of substrate composition were eliminated by the matrix matching and synchronous background correction measures, and then the analytical lines, the background correction areas and working conditions of the spectrometer are all optimized according to the spectral interference test. The technical performance reached: calibration curve correlation coefficient of 0.998 or higher, detection limit of element is 0.0001% ∼ 0.0003% and the measuring elements content in lower 0.0003% ∼ 0.0009%, RSD is less than 15% when the element content in the range from 0.001% to 0.05%, the actual sample testing results are consistent with ICP-MS. © 2018 Published und
