Description
This process refers to the production activity of producing 1 kg of silicon-calcium-barium alloy by the medium frequency furnace process. Silicon-calcium-barium alloy is a composite alloy among barium-series alloys, serving as a deoxidizer and desulfurizer in the steelmaking industry, with a dephosphorizing effect (BaP2, BaP3) as well, and is used as an inoculant and modifier in casting. The dataset includes raw and auxiliary materials such as ferrosilicon, calcium silicon, and silicon-barium, and energy inputs such as electricity; the outputs include the product inoculant, the wastes dust-collection ash and smelting slag (which can be recovered and comprehensively utilized), as well as emissions to the atmosphere and water bodies. The data inventory is formed by merging data from multiple sources, and the data representativeness is optimized using industry standards such as the 3140 Ferroalloy Industry Coefficient Handbook.
Activity Description
This activity uses an intermediate frequency furnace to produce calcium silicon barium alloy. The main raw materials are ferrosilicon, calcium silicon and silicon barium. The raw materials are added to the medium frequency induction furnace according to a certain ratio for melting. After the raw materials are melted in the furnace, they enter the mold of the molding casting machine and are cooled to obtain the finished calcium silicon barium alloy, which is then packaged for external sale. The production process includes: (1) ingredients; (2) smelting; (3) casting; (4) finished product crushing, screening and packaging.

Technology comment
An intermediate frequency furnace is used to produce calcium silicon and barium alloy. In the core smelting process, the raw materials are added to the intermediate frequency induction furnace according to a certain ratio for melting. The melting time of each furnace is about 30 minutes, and the melting temperature is 1000~1400°C.
