Abstract

The invention relates to the technical field of railway equipment and discloses a diamond saw blade for a steel rail sawing machine. The diamond saw blade is prepared from, by weight, 15.5-20 parts ofdiamond, 10-15 parts of iron powder, 5-8 parts of chromium powder, 3-5 parts of silicon carbide powder, 4-6 parts of titanium powder, 6-8 parts of zinc powder, 30-33 parts of copper powder, 2-3 partsof aluminum powder and 8-12 parts of rare earth element. The invention further discloses a production process of the diamond saw blade for the steel rail sawing machine. The produced diamond saw blade for the steel rail sawing machine is high in hardness and less prone to damages in cutting of steel rails, and the service life is greatly prolonged. In addition, due to adoption of thin-wall sharpdiamond, cutting efficiency is effectively improved, stability and quickness in cutting are achieved, and cutting quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of railway equipment, in particular to a diamond saw blade for a rail sawing machine and a production process thereof. Background technique [0002] A saw blade is a general term for thin, circular knives used to cut solid materials. Saw blades can be divided into diamond saw blades, steel saw blades and carbide saw blades. As the hardest substance at present, diamond enables diamond saw blades to cut various hard materials. At present, the existing diamond saw blades are widely used and have high strength, but the cutting efficiency is not high, and the service life is not long enough, and cracks are very easy to appear after a period of use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a diamond saw blade for rail sawing machine and its production process, which not only has high hardness, but...
