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 produced in a steelmaking furnace, typically in the form of slabs (for sheet products), blooms (for section and wire products), or tube blanks. It is an important semi-finished product in the steel industry, possessing good plasticity and machinability. Billets serve as raw materials for downstream processes and can be transformed through rolling, forging, drawing, and other processing methods into finished steel products of various specifications and shapes, such as steel plates, steel tubes, and steel bars. Billets are widely used in construction, machinery manufacturing, shipbuilding, automotive manufacturing, and other fields for producing various components and structural materials. Carbon steel, also known as plain-carbon steel, has a carbon content of approximately 0. 0.02%-2%. Carbon steel is divided into high-carbon steel, medium-carbon steel, and low-carbon steel. The higher the carbon content, the higher the hardness, strength, and wear resistance of the steel after heat treatment, but it also becomes more brittle. The lower the carbon content, the softer and more ductile the steel.

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.
