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
Billets are primary products obtained by casting molten steel from steel-making furnaces, typically in the form of slabs (for sheet production), blooms (for section and wire rod production), and tube坯. They are important semi-finished products in the steel industry, possessing good plasticity and workability. Billets can serve as raw materials for downstream processes, being rolled, forged, drawn, or otherwise processed into finished steel products of various specifications and shapes, such as steel plates, steel tubes, and steel bars. 20Cr13 stainless steel is a martensitic stainless steel, with a chemical composition primarily including approximately 0.16% to 0.25% carbon, around 12% to 14% chromium, and small amounts of other alloying elements. 25% carbon and 12% to 14% chromium, along with smaller amounts of nickel, silicon, manganese, phosphorus, and sulfur. Stainless steel billets 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.
