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 steel product manufactured through a hot-rolling process, in which preheated steel billets are rolled into flat plates of a certain thickness at high temperatures. This type of steel is characterized by excellent ductility and toughness, making it easy to form and process in industrial applications. 430 stainless steel is a commonly used ferritic stainless steel, with main components including iron, approximately 16%-18% chromium, and smaller amounts of manganese, silicon, carbon, and phosphorus. 430 stainless steel hot-rolled coil is known for its good mechanical properties and high thermal conductivity, and is widely used in household appliances, automotive parts, architectural decoration, and kitchenware.

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.
