This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. The product represented by this dataset is zinc metal, a high-purity terminal product obtained through the smelting and casting process in the hydrometallurgical zinc smelting process, with a zinc content of 99.995% and excellent purity. Its core characteristic is excellent corrosion resistance, which can effectively block the steel corrosion process, and therefore occupies a core position in the galvanizing industry. The upstream and downstream industry chains are closely connected: the upstream core raw material is cathode zinc output from the electrolysis stage of hydrometallurgical zinc smelting, and the smelting and casting process requires supporting auxiliary materials such as refining agents and covering agents; the downstream application scenarios are wide, mainly used in galvanizing processing and zinc alloy manufacturing, and can be processed into galvanized steel, zinc-aluminum alloy, zinc-copper alloy and other products, widely used in construction, transportation, electric power and general manufacturing and other industrial fields, making it a key non-ferrous metal material supporting the anti-corrosion and structural reinforcement needs of multiple basic industrial fields. The entire production process focuses on the smelting and casting stage of hydrometallurgical zinc smelting, covering the entire conversion process from the input of cathode zinc to the output of the zinc metal product. The functional/declared unit of this dataset is kg, and users can match the corresponding quantity of the background dataset according to the weight of this material used in the product being evaluated.
