The process of "continuous annealing, steel" for 1kg refers to the continuous annealing of 1kg of cold-rolled coil. "Assuming 1kg of cold-rolled coil is continuously annealed to produce 0.96448kg of continuous annealed coil". The data was aggregated from multiple sources, forming a good quality data set with a lower uncertainty in data quality. This dataset should be used in conjunction with 1kg of cold-rolled coil.
