Description
This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.
Activity Description
The production process of billets includes electric arc furnace smelting, molten steel refining, as well as casting and shaping of molten steel, covering energy consumption, material consumption, waste treatment, and environmental emissions required during the production process.
Process Description
Billets are primary products obtained by casting molten steel from steel-making furnaces, typically in the form of slabs (for plate production), blooms (for structural and wire products), and tube blanks. They are important semi-finished products in the steel industry, possessing good plasticity and workability. Stainless steel refers to alloy steel with high chromium content (>10.5%), often containing other elements such as nickel, molybdenum, vanadium, manganese, and tungsten, exhibiting characteristics such as high strength, corrosion resistance, and plasticity. Stainless steel billets are the initial form in the stainless steel manufacturing process and are typically further processed into various stainless steel products.

Technology comment
Electric arc furnace (EAF) steelmaking is a steelmaking method that uses the thermal effect of an electric arc to heat and melt the charge. Electrical energy is introduced into the electric arc furnace through graphite electrodes, with the arc generated between the electrode tips and the charge serving as the heat source. The primary raw material in EAF steelmaking is scrap steel, while alloys, lime, and carbon raisers are used as auxiliary materials. The basic EAF steelmaking process includes slag removal and furnace patching, charging of metallic materials, power supply, melting, oxidation, reduction refining, and tapping. In this unit process, the scrap steel ratio for electric arc furnace steelmaking is approximately 30%.
