Included activities starts

This activity starts with the production and import of \"hot-rolled coil, Q235B\" in this region

Included activities ends

The activity concludes with the delivery of \"hot-rolled coil, Q235B\" to the consumers of the product. Transportation is included, but losses during transit are negligible and therefore not accounted for.

Description

This dataset is a market dataset representing the consumption market in the region. The dataset includes the transportation of products from the gate to the end consumer, with transport services calculated based on the transport circumstances of the product in the region. Hot-rolled coil of carbon steel is widely used in industries such as construction, machinery manufacturing, automobiles, shipbuilding, etc., to manufacture various structural components and parts. Due to its cost-effectiveness and processing flexibility, it is one of the most commonly used types of steel. The production process of hot-rolled coil includes preheating of the steel billet, rough rolling, intermediate rolling, and finish rolling, covering energy consumption, material consumption, waste treatment, and environmental emissions required in the production process. This dataset was formed by aggregating data from multiple sources.

Activity Description

The production process of hot-rolled coil includes stages such as preheating of steel billets, rough rolling, intermediate rolling, and finish rolling, covering energy consumption, material consumption, waste management, and environmental emissions required during the production process.

Process Description

Hot-rolled coil is a type of steel product manufactured through a hot rolling process. It involves rolling preheated steel billets into flat plates of a certain thickness at high temperatures. The main characteristics of this type of steel are its excellent ductility and toughness, making it easy to form and process in industrial applications. Carbon steel, also known as plain carbon steel, contains about 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, but it also becomes more brittle. The lower the carbon content, the softer and more ductile it is. Carbon steel hot-rolled coil is widely used in construction, machinery manufacturing, automotive, shipbuilding, and other industries, for the production of various structural components and parts. Due to its cost-effectiveness and processing flexibility, it is one of the most commonly used types of steel.

Technology comment

The hot rolling process involves heating metal slabs, which have been smelted in a converter, to their plastic deformation temperature at high temperatures, typically above 1000 degrees Celsius. Subsequently, the heated slabs are continuously rolled through a series of rolling mill rolls. Primary rolling adjusts the width and thickness of the slabs through roll gap settings, whereas intermediate and finish rolling further refine the dimensions and surface quality of the coil. The entire rolling process can be细分 should be translated as subdivided here, so the final translation is: The hot rolling process involves heating metal slabs, which have been smelted in a converter, to their plastic deformation temperature at high temperatures, typically above 1000 degrees Celsius.

Primary rolling adjusts the width and thickness of the slabs through roll gap settings, whereas intermediate and finish rolling further refine the dimensions and surface quality of the coil. The entire rolling process can be subdivided into stages such as rough rolling, intermediate rolling, and finish rolling, to ensure the final coil has the required mechanical properties and surface finish.
