Control method and device for twenty-high roll mill to roll silicon steel and electronic equipment

The invention provides a control method and device for rolling silicon steel through a twenty-high roll mill and electronic equipment, and the method comprises the steps that a coiling machine is controlled to coil the silicon steel; the coiling machine is used for guiding the silicon steel into a twenty-high rolling mill for multiple passes of reciprocating rolling, and the relative rolling reduction of the edge of the silicon steel is adjusted, so that the relative rolling reduction of the edge is smaller than the relative rolling reduction of the 1/4 position of the silicon steel in the width direction and larger than the relative rolling reduction of the middle of the silicon steel; wherein when the twenty-high roll mill carries out first-pass rolling on the silicon steel, the unit post tension of the silicon steel is controlled to be preset tension. According to the method, the problem of silicon steel deviation or strip breakage when the twenty-high roll mill rolls narrow silicon steel is solved, the pr
