The invention discloses a method for extracting iron and reducing impurities from vanadium-titanium-iron concentrate, and belongs to the technical field of mineral separation. In order to achieve the purpose of extracting iron and reducing impurities from vanadium-titanium-iron concentrate, the invention provides a method for extracting iron and reducing impurities from vanadium-titanium-iron concentrate. The vanadium-titanium-iron ore concentrate is subjected to iron extraction and impurity reduction treatment through the processes of demagnetizing, screening and grading, coarse grain closed-circuit tower grinding and magnetic separation, fine grain direct magnetic separation, coarse grain and fine grain magnetic separation concentrate mixing demagnetizing closed-circuit sand grinding and magnetic separation, magnetic separation concentrate reverse flotation and magnetic separation flotation tailing mixing magnetic separation scavenging. And reverse flotation is optimized, the content of intergrowth of titanomagnetite and gangue minerals in the concentrate is reduced, the high-grade vanadium-titanium-iron concentrate with the TFe increasing amplitude being large is obtained, the TFe grade is increased to 58.12%-61.12%, and the increasing amplitude reaches 4.63%-5.07%.

This invention discloses a method for improving soil in potato cultivation, belonging to the field of agricultural soil remediation technology. Addressing the problems of soil acidification, compaction, reduced beneficial microorganisms, and severe soil-borne diseases caused by continuous potato cropping, this invention provides a synergistic improvement method integrating soil pretreatment, coupled application of microbial agents and organic fertilizers as basal fertilizers, dynamic and precise regulation throughout the growth cycle, coordinated water and fertilizer management, and post-harvest remediation. This method involves basal application of a specific ratio of compound microbial agents coupled with organic fertilizers. Based on the physiological needs and disease occurrence patterns of potatoes at different growth stages, and combined with the dynamic and precise regulation of the timing and dosage of microbial agent application through a drip irrigation system, water and fertilizer supply are simultaneously optimized, achieving synergistic effects of biological antagonism, soil ecological restoration, and crop nutrient regulation. This invention effectively improves the soil micro-ecological environment, reduces the incidence of soil-borne diseases, reduces reliance on chemical fertilizers and pesticides, and improves potato yield and quality.

The invention provides high-hardness and high-toughness steel and a heat treatment process and application thereof, and belongs to the technical field of steel heat treatment. According to the method, the steel is subjected to high-temperature austenitizing firstly, the structure in the steel can be converted into an austenitic structure, then the austenitized steel is subjected to isothermal quenching treatment, and quenching treatment is conducted at the high temperature by controlling the temperature and time of isothermal quenching treatment; most austenite structures in the steel can be converted into bainite structures, a small part of austenite structures can be converted into martensite structures, a small amount of austenite structures are left, finally tempering treatment is conducted, the internal stress of the steel is reduced, and the structures in the obtained steel are bainite + martensite + retained austenite structures, the bainite structure has high toughness, the martensite structure can improve the hardness of the steel, the steel with high hardness and high toughness is finally obtained, and the comprehensive performance is excellent.

This invention relates to the field of cloud server technology, specifically to a distributed cloud server load balancing optimization system and method based on edge computing. The method includes: initially scheduling a request signal sent by a user terminal to a preferred server with the shortest distance to the user terminal and obtaining a first utilization improvement of the overall cloud server after the initial scheduling; secondly scheduling the request signal to a candidate server and obtaining a suitability of the second scheduling and a second utilization improvement of the overall cloud server after the second scheduling; obtaining a scheduling matching degree based on the suitability, the first utilization improvement, and the second utilization improvement; if the scheduling matching degree with the largest value is non-negative, then the corresponding candidate server is the final server; otherwise, the preferred server is the final server, and the final server serves the request signal. Using this invention, the load scheduling strategy can be more reasonable, and the cloud server resource utilization rate can be higher.
