Description

This dataset is a market dataset. Each market represents the consumption mix of products within a specific geographic area, considering transportation to consumers and losses incurred during this process. This activity represents the supply of stainless steel hot-rolled coil for steel production consumption in China. The data is based on China's Customs Statistics, China Statistical Yearbook, and China Steel Yearbook.

Activity Description

This dataset is a market activity dataset, where each market represents a consumption mix of products within a specific region. The market covers producers and importers of the product within the same geographic area, considering transport to consumers and losses during this 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 certain thickness under high temperature. The main characteristics of this type of steel are its excellent ductility and toughness, making it easy to form and process in industrial applications. 304 stainless steel, also known as 18/8 stainless steel, is one of the most widely used austenitic stainless steels. Its main components include about 18% chromium and 8% nickel, as well as iron and small amounts of carbon, manganese, silicon, phosphorus, and sulfur. Stainless steel hot-rolled coil is a stainless steel product made through the hot rolling process. It is widely used in industries such as construction, automobile manufacturing, medical equipment, kitchenware, and food processing.

Technology comment

The hot rolling process involves heating the metal billets after smelting to their plastic deformation temperature at high temperatures, typically above 1000 degrees Celsius. Thereafter, the heated billets are continuously rolled through a series of rolling mill rolls. Primary rolling adjusts the width and thickness of the billets by passing them through roll gaps, while subsequent intermediate and finish rolling further refine the dimensions and surface quality of the coil material. The entire rolling process can be subdivided into stages of rough rolling, intermediate rolling, and finish rolling to ensure that the final coil material has the required mechanical properties and surface finish.
