The utility model relates to a wear-resistant white cast iron rice sieve sheet pressure strip with inserted-cast bolts. A sprue is arranged on an upper green sand mold; a runner, an ingate and a rice sieve sheet pressure strip are arranged on a lower green sand mold; a first bolt is inserted in a first bolt inserted hole; a second bolt is inserted in a second bolt inserted hole; and the upper green sand mold and the lower green sand mold are positioned and integrated by positioning pins outside a box. Molten iron of the wear-resistant white cast iron rice sieve sheet pressure strip with the inserted-cast bolts is full filled in a rice sieve sheet pressure strip cavity and casts a first bolt upper end and a second bolt upper end after sequentially entering the sprue, the runner and the ingate. According to the wear-resistant white cast iron rice sieve sheet pressure strip with the inserted-cast bolts, the bolts are firmly connected with a rice sieve sheet; and the wear-resistant property of wear-resistant whit
