Summary: The effects of oxygen enrichment on the sintering process of vanadium-titanium magnetite were investigated. Increasing the oxygen concentration from 21 to 27 vol.% resulted in improved flame front speed, yield, and productivity. Additionally, the sinter strength and desulphurization level were increased through the oxygen enrichment.

Summary: In order to improve the permeability of sinter packed bed and efficiently utilize low-grade iron bearing minerals, the impact of returned fines embedding on productivity, yield, flame front speed (FFS), tumble index (TI), and permeability of the vanadium titanium magnetite sintering process was studied. The results showed that embedding different sizes of returned fines can increase the productivity, yield, flame front speed, and tumble index to a certain extent, with the optimal sintering indices occurring at a particle size of 3 to 5 mm for the embedded return fines. The study also found that the permeability of the sinter packed bed improves as the mass ratio of the embedded return fines increases from 0% to 50%.

Summary: The direct reduction of high-chromium vanadium-titanium magnetite (HCVTM) was studied through experiments and thermodynamic analysis. The results show that the reduction degree increases with the increase of C/O ratio and temperature. Thermodynamic analysis reveals a significant mass loss in the direct reduction process of HCVTM within a specific temperature range. The isothermal reduction process can be divided into different limiting stages, with different factors affecting the reaction rate in each stage.

Summary: This study investigated the feasibility of blast furnace burden preparation using the composite agglomeration process (CAP) for titanomagnetite concentrate. The results showed that CAP optimized the particle size distribution of the feed and increased the voidage of the material layer, improving permeability index. Under specific experimental conditions, CAP achieved higher sintering yield, productivity, and RDI+3.15 compared to traditional sintering process (TSP). CAP also exhibited better agglomeration technical indexes than TSP under the same composite basicity conditions. It is an effective method for producing low-basicity sinter and reducing the proportion of expensive acid pellets in the burden.

Summary: High-pressure grinding roll (HPGR) technology can be used to pretreat vanadium-titanium magnetite (VTM) concentrate, which helps solve the low consolidation strength and high energy consumption problems. Compared with other technologies, HPGR pretreatment offers high efficiency and low energy consumption. This study discovered that VTM concentrate mainly consists of titaniferous magnetite particles with coarse size and regular shape. The lower surface area leads to lower microcrystalline and recrystallization bonding strength of titaniferous hematite in VTM pellets. HPGR pretreatment technology increases the total contact area between particles, promoting the formation of more microcrystalline and recrystallization connections of titaniferous hematite, significantly improving the performance of VTM pellets.

Summary: This study investigated the agglomeration of titanomagnetite concentrate using the composite agglomeration process (CAP) and found that CAP resulted in higher yield and better product quality compared to the traditional sintering process. The improved properties were attributed to the formation of calcium ferrite and silicoferrite of calcium and aluminum group minerals in CAP, which helped overcome the negative effects of perovskite on agglomeration.

Summary: The novel smelting reduction process shows promise in reducing environmental pollution in the ironmaking industry. Parameters such as reduction temperature, holding time, and coal ratio significantly affect the metallization rate. Achieving a metallization rate of over 70% is possible under certain conditions, but increasing the parameters further may lead to reoxidation.

Summary: This article presents the electric field waveforms of natural return strokes recorded by Foshan Total Lightning Location System. The evolution of parameters for both positive and negative return strokes is analyzed with respect to distance. The results show that the risetime, fall time, half-peak width, and zero-crossing time become longer with longer distance. The negative return strokes exhibit a more clear linear relation with distance compared to the positive return strokes. The values of overshoot duration increase with distance at 10-200 km, but become less obvious at larger distances. The values of initial peak remain the same for all return strokes. The overshoot amplitude and the ratio of overshoot to initial peak increase with distance for both positive and negative return strokes. The return stroke waveforms at far distances are more likely to exhibit clear opposite polarity overshoot.

Summary: Flourishing rare earth superhydrides are a recently discovered class of materials that exhibit near-room-temperature superconductivity at high pressures. This study comprehensively investigates yttrium superhydrides in a wide pressure range, successfully synthesizing various superhydrides and reporting their superconducting transition temperatures. The structure and superconductivity of yttrium superhydrides were examined, and the influence of external magnetic fields on superconductivity was explored. Although clathrate YH10, a potential room-temperature superconductor, was not synthesized in this study, it establishes a detailed foundation for future research on room-temperature superconductors in polynary yttrium-based superhydrides.

Summary: Chemical oxidation as a pretreatment for petroleum-contaminated soil, coupled with bioremediation, can have serious impacts on indigenous microorganisms and available nutrients. This study found that hydrogen peroxide treatments significantly promoted the removal of total petroleum hydrocarbons (TPH), especially in the initial days, and also affected the levels of dissolved nutrients. Both chemical oxidation and nutrients contribute to changes in microbial community structure and diversity. However, the long-term effects of H2O2 as a pretreatment had little impact on the soil indigenous microbial community structure and actually facilitated the continuous removal of TPH by indigenous microorganisms.

Summary: This study establishes a simulation model to investigate the lightning inductive characteristics between parallel cables. The research findings indicate that an increase in the horizontal distance between cables leads to a decrease in the cable induced voltage. Additionally, linear correlations exist between the height difference or disturbed cable length and the cable induced voltage, reaching maximum when the cables are at the same height and of equal length.
