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 hot-rolled coils includes stages such as billet preheating, roughing, intermediate rolling, and finishing rolling, encompassing energy consumption, material consumption, waste treatment, and environmental emissions associated with the production process.
Process Description
Hot-rolled coil is a type of steel product produced through the hot-rolling process, in which preheated steel billets are rolled at high temperatures into flat plates of a certain thickness. This steel is characterized by its excellent ductility and toughness, making it easy to form and process in industrial applications. Q235B carbon steel hot-rolled coil is a commonly used low-carbon steel belonging to the Q235 series under China's GB standards. The main components of Q235B include iron, less than 0.20% carbon, and less than 0. 35% silicon, along with appropriate amounts of manganese, sulfur, and phosphorus. Q235B carbon steel hot-rolled coils are widely used in construction, machinery manufacturing, steel structure engineering, bridge construction, and other fields.

Technology comment
The hot rolling process involves heating the metal billet produced from the converter to its plastic deformation temperature at high temperature, typically above 1000 degrees Celsius. The heated billet is then continuously rolled through a series of rolling mill stands. Initial rolling adjusts the billet's width and thickness through roll gap settings, while subsequent intermediate and finishing rolling further refine the dimensions and surface quality of the resulting coil. The entire rolling process can be subdivided into stages such as roughing, intermediate rolling, and finishing rolling, ensuring the final coil achieves the desired mechanical properties and surface finish.
