high performance tungsten carbide anvils

China Manufacturer Carbide Anvils

Tungsten Carbide anvils are used as key device during synthetic diamond manufacturing, bearing high tempreture and high pressure.

Cemented carbide anvils are forged, pressed and hip sintered by powder metallurgy technique. Before using it, anvils must undergo aging process to eliminate internal residual stress, in case cracking happens during usage.

Tungsten Carbide are the most superior material for application, becaused of High wear resistance, good toughness, high strength, thermal stability.Since the anvil is mounted on a large pad cubic of 6 facet piston top, cavity can reach a state of 10 to 20 GPa and 1500℃ when six anvils are drove together by cylinder which forms a closed environment. Thus tungsten carbide anvil is working under a supercritical condition, suffering stress, tensile stress and shear stress at the same time.

All anvils are treated by advanced pressing ,sintering and HIP Processes, so

so we can guarantee excellent performance of each product without any defects.

Considerations for USE:

1. Eliminate the residual stress on the carbide anvil after forming. Before using the carbide anvil, an aging treatment should be carried out, including natural aging, oven aging, boiling oil aging, vacuum aging and ultrasonic aging. The natural aging time should be no less than a month, and the aging oven temperature should be under 250°C for a period of no less than 72 hours.

2. Anvil Assembly Requirements
The taper on the anvil should be the same as that of a steel ring. The contact surface is ˃90%. The press fitting height should also be reasonable. Under cM27mm, the press fitting height is 8-10mm, and above cM27mm, the press fitting height is 10-12mm. There should be no point contact between the anvil and the spacer blocks to avoid stress concentration.

3. Requirements for Raw and Auxiliary Materials
The machining precision of the steel ring and spacer blocks should meet all requirements. The smooth finish of the inner wall of the steel ring must achieve Ra1.6. The roundness and taper should conform to the tolerances of the form and position of the anvil. The depth of parallelism of large and small spacer blocks is ˂0.02mm. The hardness is moderate. Pyrophyllite calcination temperature and time should be moderate, in order to prevent blowouts caused by poor pressure carrying performance pressure and a high moisture rate. The surface of the conductive steel ring is rust resistant, and the edge has no cracks. There is no discoloration phenomenon, even after baking. Please pay attention to moisture resistant storage.

4. Requirements for Equipment

The press should have an excellent adjusting accuracy, and leaks are prohibited. The synchronization and centering tolerance is no more than 0.2mm.
