Description
This dataset describes the process of continuous annealing of 1 kg of cold-rolled coil. In this process, it is assumed that continuous annealing of 1 kg of cold-rolled coil results in 0.96448 kg of continuously annealed coil; this dataset should be used in conjunction with 1 kg of cold-rolled coil; the data inventory was compiled from data from multiple sources.
Activity Description
Continuous annealing is a process in heat treatment of metallic materials that alters the material's structure and properties by adjusting appropriate temperature and time. The process flow includes preparation, heating, heat preservation, cooling, processing, inspection, and testing.
Process Description

Technology comment
Annealing eliminates internal stresses and work hardening in steel sheets caused by cold rolling. Continuous annealing, in contrast to batch annealing, refers to a production method where strip steel continuously passes through an annealing furnace without sealing or stopping, proceeding directly to coiling. It is suitable for mass production.
