Abstract
The invention discloses a high-strength abrasion-resistant tool with vertical alignment of primary strengthening phase fibers. The high-strength abrasion-resistant tool comprises a tool body. A plurality of strengthening phase and texture component streamline fibers are evenly distributed in the tool body, and the strengthening phase and texture component streamline fibers are formed by carrying out the directional rolling process on primary strengthening phase and texture components. The strengthening phase and texture component streamline fibers are straight-line-shaped streamline fibers, each strengthening phase and texture component streamline fiber is perpendicular to the tool faces on the two sides of the tool body, and the two ends of the strengthening phase and texture component streamline fibers are evenly distributed on the tool faces of the two sides of the tool body in a dot mode. The multiple straight-line-shaped strengthening phase and texture component streamline fibers are evenly distributed in the tool body of the tool, the effect that the tool body has the highest tensile strength in the thickness direction is ensured, and accordingly the tool has the longest service life; and as the two ends of the strengthening phase and texture component streamline fibers are distributed on the tool faces of the two sides of the tool body in the dot mode, the abrasion resistance of the tool is greatly improved.
