The invention relates to a high chromium abrasion-resistant cast iron grinding plate and the manufacturing method, which belongs to the paper making technology field. The invention comprises the following chemical compositions (weight percent): C is 2.0-3.5 percent, Cr is 22.0-28.0 percent, Mn is1.5-2.5 percent, Si is lower than 1.0 percent, W is0.25-0.60 percent, Nb is 0.03-0.12 percent, Ta is 0.01-0.04 percent, V is 0.10-0.25 percent, Ti is 0.08-0.15 percent, RE is 0.05-0.20 percent, B is 0.02-0.10 percent, Mg is 0.04-0.10 percent, and the residual is Fe and inevitable trace impurity. The grinding plate of the invention can be manufactured by adopting an electric furnace, the precoated sand mold casting is operated, the texture of the grinding plate is fine, the intensity is high, toughness is good, and the abrasion resistance and the corrosion resistance are good. The production process of the grinding plate is simple, the cost is low, the main raw material is chromium iron, and inexpensive tungsten slag ferro alloy and vanadium slag ferro alloy are added to be used as auxiliary alloying elements. The grinding plate of the invention is used, production efficiency of a pulp grinder can be improved, the pulp grinding cost is reduced, the physical property of finished paper is bettered, and the grinding plate has good economic and social efficiency.
