Problems solved by technology
Since ordinary high manganese steel has a hardness of BH200-240 after heat treatment and a work hardening hardness of HB450-520, it cannot reach a higher hardness. The existing products do not have the toughness of high manganese steel and the strength of high chromium cast iron.

Abstract
The invention discloses a device and a process for embedding high chromium cast iron into high manganese steel, and belongs to the technical field of metal material preparation devices. The device comprises a high manganese steel toothed plate and is provided with a plurality of high manganese steel toothed plate hollowed-out holes, wherein high chromium cast iron mosaic blocks are embedded into the high manganese steel toothed plate hollowed-out holes. The process comprises the following steps of completing heat treatment on the high manganese steel toothed plate and the high chromium cast iron mosaic blocks; cleaning the high manganese steel toothed plate hollowed-out holes, and grinding the high chromium cast iron mosaic blocks; feeding the ground high chromium cast iron mosaic blocks into a heat treatment furnace; melting babbitt metal by adopting a graphite crucible and keeping constant temperature for later use; laying the preheated high manganese steel toothed plate and the high chromium cast iron mosaic blocks; manufacturing a pouring cup special for pouring, and pouring the high chromium cast iron mosaic blocks; and conducting secondary grinding on the high chromium cast iron mosaic blocks subjected to alloy pouring and sending to a machine to be machined. The working efficiency of the device is superior to that of common high manganese steel, it is guaranteed that the mechanical performance of products made of two materials is not changed after heating, and the fusion effect can also be guaranteed.
Description
technical field [0001] The invention belongs to the technical field of metal material preparation devices, and in particular relates to a high-manganese steel embedded high-chromium cast iron device and process. Background technique [0002] High manganese steel is a kind of wear-resistant steel specially provided for heavy industry. Its application fields include quarrying, mining, excavation, coal industry, foundry and steel industry, etc. High-chromium cast iron is the abbreviation of high-chromium white wear-resistant cast iron. It is an anti-wear material with excellent performance that is especially valued. It has much higher wear resistance than alloy steel, and much higher toughness and strength than ordinary white cast iron. At the same time, it also has good high temperature resistance and corrosion resistance, combined with convenient production and moderate cost. Known as one of the most excellent anti-abrasive wear materials in contemporary times. Since ordina...
