Description
Steam is a byproduct of the steelmaking process. It is a key form of energy widely used in many industrial and commercial applications for purposes such as heating, electricity generation, and cleaning. 20Cr13 stainless steel hot rolled coils are renowned for their excellent hardness and strength, and are extensively used in applications requiring wear resistance and corrosion resistance, such as cutlery, medical instruments, valves, pumps, and other industrial equipment. The production process of hot rolled coils includes billet preheating, roughing, intermediate rolling, and finishing rolling, covering energy consumption, material consumption, waste management, and environmental emissions throughout the production process. This dataset is compiled by consolidating 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.
