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 producing plates), blooms (for structural and wire products), and tube rounds. They are important semi-finished products in the steel industry, exhibiting good plasticity and workability. Billets serve as raw materials for downstream processes and can be further processed through rolling, forging, drawing, and other techniques into finished steel products of various specifications and shapes, such as steel plates, steel tubes, and steel bars. Q235 steel is a commonly used carbon structural steel with good weldability, ductility, and cold-forming capability.

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.
