This dataset is a market dataset, representing the consumption market in the region. It includes the transportation of products from the factory gate to the consumer end, and the transport services are calculated based on the transport situation of the product in the region. The main components of cold rolled carbon steel plate are iron and carbon; the carbon content determines the hardness and strength of the steel. Different carbon contents allow for different grades and performance levels of cold rolled carbon steel plate, catering to various industrial needs. The production process of cold rolled plate includes processes such as acid washing and cold rolling of hot-rolled coil, covering energy consumption, material consumption, waste treatment, and environmental emissions required during the production process. This dataset is formed by aggregating data from multiple sources.
