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 steel billets includes steps such as converter smelting, molten steel refining, and casting and shaping of molten steel, covering energy consumption, material consumption, waste treatment, and environmental emissions during the production process.
Process Description
Billet is a primary product obtained by casting molten steel from a steelmaking furnace, typically in the form of slabs (for sheet production), blooms (for section and wire rod production), or billets (for tube production). It is an important semi-finished product in the iron and steel industry, possessing good plasticity and workability. Billet can serve as a raw material for downstream processes, being further processed through rolling, forging, or drawing to produce finished steel products of various specifications and shapes, such as steel plates, steel tubes, and steel bars. 304 stainless steel, also known as 18/8 stainless steel, is one of the most widely used austenitic stainless steels. Its main components include approximately 18% chromium and 8% nickel, along with iron and small amounts of carbon, manganese, silicon, phosphorus, and sulfur. Stainless steel slabs are the primary form in the stainless steel manufacturing process and are typically further processed into various stainless steel products.

Technology comment
Basic oxygen steelmaking is a common steelmaking process. During smelting, high-temperature combustion and oxygen blowing remove impurities such as sulfur and phosphorus from the molten steel. By controlling the amount of oxygen blown in and the processing time, the oxygen atmosphere and reaction conditions inside the furnace are regulated, thus controlling the composition and quality of the alloy. Subsequently, the molten and refined steel is transferred via ladle to a turret, which rotates to the casting position and pours the steel into a tundish. The tundish then distributes the molten steel through nozzles into individual molds, where it solidifies upon cooling to form shaped raw steel billets.
