Hot rolled strip, the theory of the thinnest, how thin rolling, why not rolling too thin, is the material or the reasons for plate shape?
Tangshan Iron and steel production line design capacity of 0.8mm, the thin can be rolled to 1.8 or limited production, steel level, the purity of molten steel are related, and also there is a certain relationship between the plate width.
The reasons are manifold. Equipment capacity, iron oxide scale, strip temperature control, steel plate type and so on restrict the minimum reduction of hot rolled strip.
Thinning is related to width. But after a certain width, the amount of thinning has little to do with the width. The theory of hot rolling can be rolled to 0.8mm, and in practice, the 1.2mm is virtually useless.
