This invention belongs to, but is not limited to, the field of intelligent accounting archive technology, and discloses an intelligent archiving method for accounting archives and a data verification and rollback control method. The method includes: dynamic QR code technology + barcode scanner / PDA + NLP image type recognition + RFID archive borrowing to achieve intelligent archiving; when a document is saved, a QR code is generated based on the relevant information of the document, and the corresponding metadata information is updated at different business nodes; sub-codes and master codes are used to verify data uniqueness; a communication protocol with the barcode scanner / PDA ensures data security; NLP identifies image types, and different types of attachments are verified in different ways; RFID facilitates quick retrieval when borrowing archives. This invention not only effectively improves the management efficiency of enterprises, but also brings positive impacts on energy conservation, environmental protection, and sustainable development. Through optimization of each link, by reducing paper and energy consumption, improving resource utilization efficiency, and enhancing the enterprise's risk resistance, a win-win situation of economic and environmental benefits is ultimately achieved.

This invention relates to the field of metallurgical technology, specifically to a method for effectively recovering metallic silicon from industrial silicon slag. The method involves first crushing the silicon slag, adding plasma water for slurry preparation, obtaining a silicon slag slurry, then adding a modifier, inhibitor, trapping agent, and frother to generate bubbles. The slurry is then refined using electromagnetic slag-forming in a medium-frequency induction furnace, and finally poured into a mold for cooling to obtain metallic silicon. The modifier is quicklime powder, the inhibitor and trapping agent are a mixture of various components, the frother is No. 4 flotation oil, the slag-forming agent is a mixture of base materials and auxiliary materials, and the gas is a mixture of argon, chlorine, and other gases. This method can solve the problems of high impurity and complex chemical composition in industrial silicon slag, improving the purity of the recovered metallic silicon.
