The invention relates to a method for improving the machining properties of Cr18W2 wear-resistant white cast ion. Tungsten alloy-containing white cast ion is a wear-resistant material having the characteristics of high hardness, good wear resistance and the like, and less study reports on the machining properties of the tungsten alloy-containing white cast ion exist at present. The method comprises the following steps of: a. determining the change conditions of a casting-state structure and carbides of the Cr18W2 wear-resistant white cast ion and the relation between the change conditions and the properties according to the change of different alloy contents; b. changing the structure form and the properties of the Cr18W2 wear-resistant white cast ion by using a heat treatment process; and c. carrying out subsequent heat treatment according to utilization requirements. The invention is used for improving the machining properties of the Cr18W2 wear-resistant white cast ion.
Description
Technical field: [0001] The invention relates to a method for improving the processing performance of Cr18W2 anti-wear white cast iron. Background technique: [0002] my country's tungsten resources are extremely rich, and white cast iron made by adding a certain amount of tungsten to high-chromium cast iron is a new type of wear-resistant material in line with my country's national conditions. Tungsten-containing alloy white cast iron is an anti-wear material with high hardness and good wear resistance. Cr18W2 alloy white cast iron is a kind of wear-resistant material developed according to the resources of our country. It not only has high wear resistance, but also has good casting performance. It is a promising material. In Cr-W alloy white cast iron, tungsten is distributed in the matrix and carbides, and tungsten can change the morphology and distribution of carbides. In order to expand the application range of tungsten alloy white cast iron and ensure safe and reliab...
