At present, some traditional two-roll roll coaters have emerged on the market, which adopt the mode of coating liquid spraying and two-roll squeezing, only requiring that the coating liquid can be coated, and usually mainly use low-grade, low-quality, and relatively thick silicon steel. The coating of high-grade and high-quality silicon steel still relies on a three-roll coater to achieve the coating quality. However, in the metallurgical industry, most of the silicon steel roll coater equipment is still imported. For silicon steel roll coaters, the existing domestic roll coaters have the following deficiencies:
