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 high-titanium slag by the electric furnace process. High-titanium slag is a titanium ore enrichment product with a TiO2 content ≥85%, and is a high-quality raw material for producing titanium tetrachloride, titanium dioxide and titanium sponge products. The production activity of this product includes the processes of auxiliary stages such as raw material supply, electric furnace smelting, finished product processing and the dust removal system. This dataset includes the input of raw and auxiliary materials such as titanium concentrate, coke and electrode paste, and energy such as electricity; outputs include the products high-titanium slag and ferrotitanium, waste dust (recoverable to cement plants for comprehensive utilization), and 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
The production of high titanium slag is based on titanium concentrate as raw material and coke as reducing agent. They are fully mixed in a certain proportion and continuously added to the electric furnace at a certain speed. Electric energy is used to perform high-temperature reduction smelting in the electric furnace. Under the action of arc heat, the iron oxides in the titanium concentrate are selectively reduced to metallic iron, and the elemental iron is melted into molten iron, which is cast into a titanium-ferroalloy alloy. The titanium oxides are enriched in the slag, and high-titanium slag is obtained after the slag-iron separation. At the same time, the titanium dioxide in the titanium concentrate is also partially reduced to low-valent titanium oxides and dispersed in the slag, thereby achieving natural enrichment of titanium slag, and together constitute high-titanium slag. The titanium slag is cooled, crushed and magnetically separated to obtain high titanium slag products. This production process mainly includes raw material storage, batching, distribution, electric furnace charging, titanium slag electric furnace smelting, slag tapping, iron tapping, titanium slag processing and other processes.
Process Description
High titanium slag is a high-content titanium dioxide enrichment obtained by melting titanium ore by heating in an electric furnace to melt and separate titanium dioxide and iron in the titanium ore. It is a high-quality raw material for the production of titanium tetrachloride, titanium dioxide and titanium sponge products.
