The invention relates to the technical field of separation and purification, and provides a separation process of high-purity curcumenone diol, which comprises the following steps: S1, passing a curcumenone diol extracting solution through a normal-phase liquid chromatographic column for chromatography and elution, and collecting the eluent for rotary evaporation to obtain a crude product; and S2, dissolving the crude product, carrying out chromatography and elution through a reversed-phase liquid chromatographic column, collecting the eluent, and carrying out rotary evaporation and drying to obtain curcuma zedoary aureondiol. According to the technical scheme, the problem that in the prior art, the purity of curcuma zedoary aureondiol extracted from zingiberaceae plants is low is solved.

This invention relates to the field of alloy cold heading steel production technology, and discloses a pearlitic phase transformation process for alloy cold heading steel that reduces or eliminates annealing. The process includes S1 precise composition design, S2 converter smelting stage, S3 LF refining stage, S4 vacuum treatment stage, S5 continuous casting stage, S6 rolling stage, S7 core controlled cooling stage for pearlitic phase transformation, S8 heat preservation and channel strengthening stage, and S9 process monitoring and closed-loop adjustment. This process achieves sufficient pearlitic phase transformation and significant suppression of harmful phases: by precisely controlling the cooling rate at 0.25-1.0℃ / s in the core controlled cooling stage, combined with heat preservation synergy within the 620-746℃ pearlitic phase transformation range, the pearlitic content of the steel is stably maintained at ≥85%, the bainite content ≤5%, and the martensite content ≤2%, completely solving the problem of excessive hardness caused by excessive harmful phases in traditional processes, and providing core microstructure protection for reducing or eliminating annealing.

The invention relates to the technical field of energy storage battery electrolyte, and particularly discloses a preparation method of iron-chromium flow battery electrolyte, which comprises the following steps: by taking high-purity iron powder, hydrochloric acid and chromic anhydride as raw materials, carrying out chemical reaction under specified conditions to generate ferric trichloride and chromium trichloride. And after the reaction is finished, continuously adding high-purity iron powder to completely convert the ferric iron into ferrous iron, and finally supplementing the balance of required chromium chloride and hydrochloric acid, thereby directly preparing the required qualified iron-chromium flow battery electrolyte. The required iron-chromium flow battery electrolyte can be simply and efficiently prepared, and compared with a traditional chlorine salt compounding process, the production link is simplified, and the production cost is reduced. The preparation method disclosed by the invention is simple in process, time-saving and labor-saving, free of any emission and more environment-friendly.
