ANNEALED COLD ROLLED STEEL AND METHOD FOR PREPARING SAME

摘要

In accordance with the present invention, disclosed herein is a cold rolled steel comprising a continuous sheet of rolled steel rolled to form a plurality of concentric layers, wherein each layer of the plurality of layers is separated a predetermined distance from each adjacent layer such that a gap is formed between each adjacent layer, and wherein each separate spacer comprising of a heat resistant material capable of withstanding temperature of at least about 600 °C is present between each adjacent layer. Also disclosed herein, are processes to anneal the continuous sheet of rolled steel exhibiting a reduced carbon footprint.
