This dataset represents the hot-rolled coil product produced by the ESP (Endless Strip Production) process. This product is a black continuous steel coil with a surface covered by scale, and is an important intermediate product of the iron and steel industry. Its core feature is that, through ESP technology, a high degree of integration of molten-steel casting and rolling is achieved, seamlessly connecting the continuous casting, rolling and cooling processes, thereby possessing the characteristics of high production efficiency, low energy consumption, uniform product performance and excellent dimensional accuracy. The key upstream starting raw material of the product is qualified molten steel smelted in a converter or electric furnace, which directly enters the rolling stage after thin-slab continuous casting; the downstream is widely applied in deep-processing fields such as cold-rolled substrate, hot-rolled pickled plate, structural steel and line-pipe steel, and is a basic material for the automotive, machinery, construction and manufacturing industries. The dataset includes the main raw and auxiliary materials, energy and wastes of the production process, while infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.
