1

Place the ring finger under a stream of cool water. The cool temperature to reduce swelling of the finger.

 

2

Apply liquid soap to the ring finger. Rub the soap around the ring and finger to lubricate the ring. Gently twist the ring from side to side to lubricate the underside with soap. Liquid soap will not damage tungsten.

 

3

Gently pull the ring toward the knuckle. Work the ring down the shaft of the finger until it slides off.

The purpose of mixing processes is to bond a variety of carbides and metal powder prepared according to a different Alloy composition, a mixed powder with uniform particle size , the main means of milling .

WC-Co, WC-TiC-Co cemented carbide production mix drying process

Vibration Drying: vibrating a vibration dryer eccentric shaft driven by a motor which generates the vibration frequency of 1400 times / min, the amplitude of 5 ~ 10mm.

Vacuum drying : vacuum drying carbide mixture drying process more 

advanced methods , currently used devices are more extensive bi-cone vacuum dryer .Like this:

WC-Co, WC-TiC-Co cemented carbide production mix mixed plastic ( wax ) - pelleting process

Good mix mixture before the incorporation of some of the organic compounds to suppress , the purpose of the powder mixture 6 is to improve the binding between the state so that the mixture has good fluidity, improve the uniformity of the green density and strength .

WC-Co, WC-TiC-Co cemented carbide production mixes Quality Control: Quality control mixture mainly through chemical analysis and identification block sintering tests to achieve.

WC-Co, WC-TiC-Co cemented carbide forming method of production mix

WC-Co, WC-TiC-Co cemented carbide products in a variety of molding methods . The production of commonly used method for forming a molded , cold isostatic pressing , extrusion molding plasticized powder , powder injection molding .

WC-Co, WC-TiC-Co cemented carbide sintering

Carbide sintering methods are: hydrogen sintering, vacuum sintering, hot pressing , vacuum - pressure sintering, hot isostatic pressing and sintering . In recent years, for the preparation of ultra-fine grain carbide, microwave sintering , spark plasma sintering process has been studied and utilized.

WC-Co, WC-TiC-Co alloys

Alloy Density : Density is the assessment of the performance of basic indicators carbide . Alloy composition is constant, the degree of size can reflect the organizational structure of carbide .

Coercive Force (Hc): The bonding metal alloy ferromagnetic material, so that a magnetic alloy .

Magnetic saturation (Com): saturation magnetic alloy of cobalt content in the alloy only , and is independent of WC grains , therefore , the magnetic saturation value can be identified with the alloy composition and alloy clamp the existence of non- magnetic phase .

Hardness (HRA): hardness carbide mechanical properties of a major general in the 83.0-94.0HRA between .
Bending strength : bending strength is a measure of an important indicator of quality carbide , generally between 1300-4000MPa .

Compressive strength: Compressive strength indicates the ability of an alloy to withstand compressive loads , WC-Co alloys with cobalt content increases strength and decreases WC grains .

Toughness : Toughness is a measure of mining carbide and wilt under harsh conditions intermittent cutting tools is an important indicator , WC-Co alloy toughness increases with the cobalt content and WC grain increases.
