Included activities starts

This activity starts with the production and import of 'steel billets, carbon steel' in this region

Included activities ends

The activity concludes with the delivery of 'steel billets, carbon steel' to the consumers of the product. Transportation is included; however, losses of the product during transit are negligible and therefore not accounted for.

Description

This dataset is a market dataset, representing the consumption market in the region. It includes the transportation of products from the gate to the consumer end, and the transport services are calculated based on the transportation situation of the product in the region. Steel billet can be used as raw material for downstream processes, and after processing technologies such as rolling, forging, and drawing, it can be made into finished steel products of various specifications and shapes, such as steel plates, steel pipes, steel bars, etc. In fields like construction, machinery manufacturing, shipbuilding, and automobile manufacturing, steel billets are widely used to manufacture various parts and structural materials. Carbon steel, also known as carbon steel, has a carbon content of approximately 0. 02%-2%. Carbon steel is categorized into high-carbon steel, medium-carbon steel, and low-carbon steel. The higher the carbon content, the greater the hardness, strength, and wear resistance of the steel after heat treatment, but it becomes more brittle. Lower carbon content results in softer and more ductile steel. This dataset is formed by aggregating data from multiple sources. The dataset encompasses a mix of converter steelmaking and EAF steelmaking technologies, describing the scrap steel input in EAF steelmaking to be approximately 0.43kg/kg steel.

Activity Description

The production process of Steel billet includes the converter steel-making process, steel water refining, as well as the casting and forming of steel water, covering energy consumption, material consumption, waste treatment, and environmental emissions required in the production process.

Process Description

Steel billet is a primary product obtained by casting steel from a steelmaking furnace, typically in the form of slabs (for plate production), blooms (for section and wire rod production), and billets (for pipe production). It is an important semi-finished product in the iron and steel industry and possesses good malleability and workability. Steel billet can be used as raw material for downstream processes. By undergoing processing techniques such as rolling, forging, and drawing, it can be made into various specifications and shapes of finished steel products like steel plates, steel pipes, steel bars, etc. In fields such as construction, machinery manufacturing, shipbuilding, and automobile manufacturing, steel billets are widely used to produce all kinds of parts and structural materials. Carbon steel, also known as carbon steel, has a carbon content of approximately 0. 02%-2%. Carbon steel is classified into high-carbon steel, medium-carbon steel, and low-carbon steel. The higher the carbon content, the greater the hardness, strength, and wear resistance of the steel after heat treatment, and the more brittle it becomes. The lower the carbon content, the softer and more ductile it is.

Technology comment

Steelmaking technologies primarily include converter steelmaking technology and EAF steelmaking technology. Converter steelmaking is a common technology in the field, wherein the refining process, high-temperature combustion and oxygen blowing is used to remove impurities from the molten steel, such as sulfur, phosphorus, etc. By controlling the amount of oxygen blown and the production time, the oxygen atmosphere within the furnace and the reaction conditions are regulated to control the composition and quality of the alloyed steel. Molten refined steel is subsequently transported to a rotating platform via a ladle. Once the platform rotates to the casting position, the molten steel is poured into a tundish, from which the steel is distributed via spout to multiple crystallizers. After cooling and solidification, these form shaped crude steel billets. Electric arc furnace steelmaking is a steelmaking method that uses the thermal effect of electric arcs to heat and smelt furnace materials. Electrical energy is input into the electric arc furnace through graphite electrodes, using the electric arc between the electrode tip and furnace material as the heat source for steelmaking. Electric arc furnace steelmaking primarily uses scrap steel as the main raw material, with alloy, limestone, and carbon enhancers used as auxiliary materials. The basic process of electric arc furnace steelmaking includes slag removal and furnace supplementation, loading of metallic furnace materials, power feeding, melting, oxidation, reduction refining, and steel tapping. In this unit process, the scrap steel ratio of electric arc furnace steelmaking is approximately 40%.
