Production and rolling method for 4-5mm ultra-thin slabs

The invention belongs to the technical field of smelting and steel rolling and particularly relates to a production and rolling method for 4-5mm ultra-thin slabs. The method comprises the steps of (1) adjusting work equipment; (2) adjusting the roller convexity and roasting rollers; (3) determining parameters and performing rolling. The method is used for producing 4-5mm ultra-thin slabs, so that production of the ultra-thin slabs is achieved, good theoretical reference and instance analysis are provided for production of original ultrathin smooth steel slab products of same industries, production accuracy and stability of medium-thick slabs of thin specifications are improved, and apparent popularization and application prospects are provided. Compared with production methods for rolling slabs, the production and rolling method for slabs of 4-5mm ultrathin specifications has the advantages that processes such as uncoiling and straightening are omitted, energy consumption is reduced for the society, costs are
