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 producing 1 kg of ferrotitanium by the aluminothermic process. Ferrotitanium is a ferroalloy with titanium and iron as its main components, with a Ti grade of 25-35%, used as a deoxidizer, desulfurizer, degasser and alloying agent in steelmaking. The production activity of this product includes process steps such as raw material treatment and batching, smelting, finished product processing, and auxiliary stages such as the dedusting system. This dataset includes the input of raw and auxiliary materials such as titanium concentrate, aluminium granules, iron ore powder, ferrosilicon powder and lime, and energy such as electricity; the output includes the product ferrotitanium, the waste dedusting ash and smelting slag (which can be recycled for comprehensive utilization), as well as emissions to air; infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary. The data inventory is formed by merging multi-source data, and the data representativeness is optimized using industry standards such as the '3140 Ferroalloy Industry Coefficient Handbook'.
Activity Description
This process uses the thermite method to produce ferrotitanium. The main steps involve drying and dehydrating the raw materials, titanium concentrate and iron ore powder, in a rotary kiln. Then the titanium concentrate, ferrosilicon powder, lime, etc., are mixed in a hopper in specified proportions and smelted in a furnace shell. Aluminum particles are used to aid combustion. After combustion is complete, the materials naturally separate to yield finished ferrotitanium. The specific process includes the following steps: (1) pre-treatment (drying); (2) batching; (3) smelting; (4) iron removal and cooling; (5) finishing and packaging; (6) warehousing.

Technology comment
The principle of thermite smelting of ferrotitanium is to use aluminum as a reducing agent, which reduces TiO₂ to metallic Ti at high temperatures and combines with molten iron to form high-titanium ferrotitanium, while releasing a large amount of heat. From a thermodynamic perspective, when Al is used to reduce TiO₂ to metallic Ti under high-temperature conditions, a portion of TiO₂ is also reduced to TiO. The reduction of TiO by Al can only proceed when the concentration of Al in the alloy and the concentration of TiO in the slag are high. TiO is a strongly basic oxide that readily forms a complex with Al₂O₃ in the slag, driving the reduction of TiO₂ toward TiO. To prevent this reaction from occurring, a stronger basic oxide (CaO) is added to replace TiO in binding with Al₂O₃, thereby directing the reaction toward the generation of Ti.
