The scraper produced by Henan Shuangzhi is mostly made of materials of 27SiMn, 40Cr and 40Mn2. After forging, the strength, hardness and toughness of the above three materials are all improved, and the abrasion resistance and bending resistance are also greatly improved. The specific processing technology of scraper is as follows: blanking â?? heating â?? forging blank â?? punching â?? removing burr â?? tempering â?? shot blasting â?? surface treatment â?? quality inspection. Forging process is the key of processing technology. After the blank is heated in the reheating furnace, the blank is made by forging hammer. During the forging process, the oxide skin on the blank surface is knocked off, and the depth and hardness of the hardening layer of the scraper blank are more guaranteed. Henan Shuangzhi supplies the following types of scraper: 101S-01 scraper, 150S0117-1 scraper, 5GL02-2A scraper, 1GL3-1 scraper, 43GL03-1 scraper, 77GL3-1 scraper, 3S001-00/14 scraper, 8GL04-1 scraper, etc. More scraper models can contact us for verification, provide drawings can also provide customized services.
