Description
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 manganese metal, a silver-gray, hard and brittle metal with active chemical properties but relatively strong corrosion resistance, having good alloying ability and deoxidation and desulfurization functions. Manganese metal is an important industrial raw material. Its upstream main raw material is manganese ore (such as manganese oxide ore), and downstream applications are wide, with the vast majority directly or indirectly consumed in iron and steel production to improve steel performance; it is also used in batteries, electronics, specialty chemicals, food, aerospace and other industrial fields. The entire production process includes the core processes of drying, rough smelting, refining, dilution, and casting of manganese ore. The dataset includes the main raw and auxiliary materials, energy and waste of the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.

Technology comment
The manganese metal process mainly includes five stages: drying, rough smelting, refining, dilution, and casting. Manganese oxide ore is transported into a rotary kiln for drying and preheating, and the hot material is quantitatively added to the submerged arc furnace via a hot ore bin and a hot vibrating screen. After rough smelting in the submerged arc furnace, the material is sent to a refining electric furnace for further smelting. The refining furnace operates according to the shaking ladle process, where the refining of manganese metal is completed through steps such as feeding, power supply, and slag tapping. The refined slag is depleted by adding high-silicon silicomanganese in the shaking ladle. The final molten manganese metal or high-carbon ferromanganese is cast, cooled, and finished to obtain the final product.
