According to the stress state of the rolling wall workpiece under the actual working conditions, the service characteristics (high-cycle strong impact, friction, extrusion, and shearing), combined with the current domestic use of wear-resistant materials, a series of comparisons Analytical and repeated tests Shandong Shuoyuan Industrial Machinery Co., Ltd. selected high-manganese steels with strong potentials (work hardening ability) under strong impact, friction, extrusion, and shear conditions as the materials for the production of rolling wall workpieces. The surface is bright and smooth, with no casting defects such as sticky sand, sand inclusions, pores, shrinkage holes, and the service life exceeds that of the purchased similar products.
