Piercing Mill Wear Plate

This product is an important wear-resistant part for seamless tube piercing equipment. It takes friction and impact from hot billets. Our factory has deep experience in wear-resistant casting production. We strictly control casting process parameters. We ensure casting density and wear resistance. Our testing equipment includes hardness testers and roughness testers. We test hardness and roughness on every wear plate before shipment. The Piercing Mill Wear Plate is built for reliable piercing service.

Surface roughness is controlled at Ra ≤ 6.3μm. A smooth working surface reduces friction with the billet. We offer built-in water cooling as an option for this product. Water cooling effectively reduces working temperature. We do hydrostatic testing on water-cooled models. Test pressure is 1.2MPa. Holding pressure for 20 minutes without leakage is the pass standard. We strictly forbid weld repair on the main working surface. Weld repair causes local hardness and structure changes. This leads to high-temperature peeling. Our Piercing Mill Wear Plate delivers consistent piercing performance.

Curved profile dimension tolerance for this product is controlled within ±0.08mm. Working surface curvature is controlled within 0.06mm per meter. These precision levels ensure smooth contact with the billet. We strictly control casting quality for this product. The working surface must have no cracks, cold shuts, dense porosity, or shrinkage. These defects cause wear plate peeling during use. We do penetrant inspection on every wear plate. We check for visible micro-cracks on the working surface. Micro-cracks grow under high-temperature impact. This causes premature failure. Every Piercing Mill Wear Plate meets these strict standards.

This product has been used in many domestic seamless tube mills. Customers report good service life and wear resistance. We also custom-make wear plates based on customer drawings. Our technical team helps with selection. Choose our Piercing Mill Wear Plate for reliable piercing service.
