Abstract
The invention discloses a shield cutter for complex geology. The shield cutter comprises the following components in percentage by weight: 14.5 to 15 percent of Co powder with the purity of 99.9 percent, 0.1 to 0.5 percent of Re, 11 to 15 percent of WC (Wolfram Carbide) powder with the granularity of 3 to 5 microns, 20 to 22 percent of WC powder with the granularity of 8 to 13 microns, and the balance of WC powder with the granularity of 5 to 8 microns. The complex geological shield cutter has the advantages that a high-toughness and high-wear resistance alloy produced by mixing medium particle primary WC with large proportion, crude particles with medium proportion and relatively thin medium particle primary WC with small proportion can well adapt to ultra-complex geological conditions in China, the fail rate of the shield cutter is reduced, the shield efficiency is improved, the bending resistance is greater than 3,000N/mm<2>, and the hardness is HRA85.
Description
Technical field
The present invention relates to complicated geological shield structure cutter.
Background technology
Existing shield structure cutter is all adopt the manufacture of W-Co kind alloy, cannot meet shield cutter and bear the effect such as extruding, impact, scraping continuing from underground soil property, hydraulic pressure etc. and vary.
Summary of the invention
The object of the present invention is to provide complicated geological shield structure cutter, effectively can solve existing shield structure cutter and cannot meet the problem that shield cutter bears the effect such as extruding, impact, scraping that is lasting from underground soil property, hydraulic pressure etc. and that vary.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: complicated geological shield structure cutter, comprises following component by weight: the Co powder of purity 99.9%: 14.5% ~ 15%, the WC powder of Re:0.1% ~ 0.5%, 3-5 μm: 11% ~ 15%, the WC powder of 8-13 μm: 20% ~ 22%, all the other are the WC powder of 5-8 μm.
