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. This process refers to the production activity of smelting 1 kg of high-carbon ferromanganese by the submerged arc furnace process. High-carbon ferromanganese is an alloy composed of manganese and iron, with a carbon content of 7.0-8.0%. Electric furnace high-carbon ferromanganese is mainly used in steelmaking as a deoxidizer, desulfurizer and alloying additive; in addition, with the advancement of medium- and low-carbon ferromanganese production processes, high-carbon ferromanganese can also be used to produce medium- and low-carbon ferromanganese. This dataset includes the input of raw and auxiliary materials such as manganese ore, coke and electrode paste, and energy and energy media such as electricity and water; the output includes the product high-carbon ferromanganese, the by-product gas power generation, the waste slag and dedusting ash (which can be recycled to cement plants), as well as emissions to water and air. The data inventory is formed by merging multi-source data, and the data representativeness is optimized using industry standards such as the 'Cleaner Production Standard - Iron and Steel Industry (Ferroalloy)' and the '3140 Ferroalloy Industry Coefficient Handbook'.
Activity Description
The production of high-carbon ferromanganese by the submerged arc furnace method is a method of producing high-carbon ferromanganese in a reduction electric furnace with a short furnace body using electricity as the heat source and coke as the reducing agent. The smelting principle is mainly the process of thermal decomposition of high-valent oxides of manganese and reduction of low-valent oxides by carbon. The raw materials for the production of high carbon ferromanganese consist of manganese ore, electrode paste and coke. After the raw materials pass the inspection, they are stored in the raw material shed. The process flow includes: 1) batching and loading; 2) smelting section; 3) tapping and casting; 4) slag tapping; 5) finishing and packaging.
Process Description
High carbon ferromanganese is an alloy composed of manganese and iron. The high-carbon ferromanganese products in this data set comply with the quality standards for high-carbon ferromanganese in Ferromanganese (GB/T3795-2014), with a carbon content of 7.0%-8.0%. Electric furnace high carbon ferromanganese is mainly used in steelmaking as deoxidizer, desulfurizer and alloy additive. In addition, with the advancement of medium and low carbon ferromanganese production technology, high carbon ferromanganese can also be used to produce medium and low carbon ferromanganese.

Technology comment
Submerged arc furnaces use carbon as a reducing agent to reduce oxides in ores to produce ferroalloys. The mixed charge is added into the furnace, and the electrodes are buried in the charge. Heating is achieved by arc heat and resistance heat generated by the electric current passing through the charge. The molten metal and slag collect at the bottom of the furnace, and iron and slag are regularly tapped through the taphole. The production process is continuous.
