Description
Steam is a byproduct of the hot rolled coil production process. It is a critical form of energy widely used in many industrial and commercial applications for purposes such as heating, electricity generation, and cleaning. Q235B carbon steel hot rolled coil is a commonly used low-carbon steel belonging to the Q235 series under the Chinese GB standard. 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. The production process of hot rolled coils includes billet preheating, roughing, intermediate rolling, and finishing rolling, covering energy consumption, material consumption, waste treatment, and environmental emissions required during production. This dataset is formed by merging data from multiple sources.

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.
