[CN201710065181.X] Strengthening process of high manganese steel hammer head
[CN201710065181.X] A strengthening process for high manganese steel hammers Title: A strengthening process for high manganese steel hammers Application Number: CN201710065181.X Applicant: Zaozhuang Ruilong Machinery Manufacturing Co., Ltd. Application Date: 2017-2-6 Patent Type: Invention Application The present invention provides a strengthening process for high manganese steel hammers. First, chromium powder and graphite powder are evenly mixed at a ratio of 1:2 to prepare high strength wear-resistant powder material for standby; then heat the surface of the high manganese steel hammer head to the melting point of the body material, and then evenly spray a layer of high-strength wear-resistant powder material on the surface to coat the surface of the high manganese steel hammer head with a layer of high-strength wear-resistant powder material for 60-120 minutes. Then, the high manganese steel hammer head covered with wear-resistant layer in step 2 is pressed by a forging machine to forge it. Finally, the forged high manganese steel hammer head is cooled to obtain the finished product. The steps 2) -4) are performed in a vacuum state. The beneficial effects of the present invention are: the process of the present invention is simple, the manufacturing cost is low, the hardness and wear resistance of the high manganese steel hammer can be improved, and the service life of the high manganese steel hammer can be prolonged.
