Preparation method of cold roll free of surface clutter and controllable in liquidation and cold roll

The invention discloses a preparation method of a cold roll free of surface clutter and controllable in liquidation and the cold roll. The preparation method comprises the steps that alloy raw materials are sequentially subjected to electric arc smelting, LF smelting and VD smelting, and alloy liquid is obtained; the alloy liquid is subjected to die casting, and a casting is obtained; the casting is subjected to red delivery annealing, and an annealed casting is obtained; carrying out electroslag remelting on the annealed casting to obtain a cast ingot, wherein the electroslag remelting needs to adjust an electroslag furnace according to the melting quality of the annealed casting to control the melting speed, the power, the resistance and the resistance swing value; and the cast ingot is heated and then sequentially subjected to homogenization, forging and heat treatment, and the cold roll is obtained. According to the method, the electric slag furnace is adjusted to control the melting speed, the power, the
