Tungsten carbide roll ring has good abrasion resistance, high-temperature red hardness, thermal conductivity and high temperature strength and other characteristics, it has been widely used in making high-speed wire rod, bar, rebar, and other rolling seamless steel pipe production. During normal use, the surface due to the impact of high frequency alternating thermal shock and hot water fog and thermal fatigue cracking, commonly known as crack, different forms of wear or fracture failure is the main reason in this case appears thermal fatigue crack initiation and propagation. When the groove face cracked it must be grinded to prevent crack propagation caused by abnormal breakage roller ring.
Tungsten carbide roll rings performance requirements
When the roller ring used, the roll diameter roller ring is smallest , and line the fastest, roll ring subjected to thermal shock highest frequency. Therefore, it requires roll ring material having excellent abrasion resistance to ensure the dimensions of finished wire after a certain amount of rolling ; and requires a high fracture toughness to resist the thermal expansion of the higher frequency shocks caused thermal fatigue cracks; the same time, need to have a high thermal conductivity to suppress thermal fatigue crack initiation. During use, the maximum operating speed of tungsten carbide roll rings up to 18000 r / min, and rolling up to the maximum temperature of the contact 1200 ¡æ.

Tungsten Carbide Dental Burs Description
Tungsten carbide dental burs are manufactured from a single piece of tungsten carbide (TC) or from a TC tip brazed onto a surgical steel stem. The range includes patterns designed to meet the needs of all surgery and laboratory applications.
Tungsten Carbide Dental Burs Applications
Tungsten carbide dental burs can be used to cut or polish a wide variety of materials encountered in dentistry. These include tooth material such as enamel, dentine and bone, dental materials such as amalgam, composite, glass-ionomer cements, polymer and ceramic veneers and precious and not-precious alloys. The bur pattern will be selected to cut a specific material in a specific application and the following table gives guidance on selection.
Safety in Tungsten Carbide Dental Burs Use
Eye protection must be worn to protect against ejected particles.
Surgical mask must be worn to avoid inhalation of aerosol or dust generated.
Inspect the bur for broken flutes before each use and discard defective burs.
Ensure that the bur is fully seated and gripped in the handpiece collet.
Maintain handpieces in good working order and correctly lubricated.
Do not exceed the maximum speeds tabulated above.
Move the bur continuously when in use to avoid localized heating.
Clean and sterilize the burs in accordance with the directions below before first use an before each reuse.
These instructions are applicable to the processing of tungsten carbide, diamond and steel dental rotary instruments before first use and each reuse. Dental rotary instruments are supplied mechanically clean but are not sterile. They should therefore be sterilized before first use. Steel burs are single use devices and the instructions therefore only apply to processing before first use.
Used burs should be considered as contaminated and appropriate handling precautions should be taken during reprocessing. Gloves, eye protection and a mask should be worn. Other measures may be required if there are specific infection or cross-contamination risks from the patient.
With the exception of steel burs, which are single use devices, reprocessing will have little effect on dental burs. The end of life is determined by wear and damage in use and the burs should be inspected for defects during the preliminary cleaning process.
Unless there is specific infection or cross-contamination risks, there are no special requirements for containment. The burs can be transported wet or dry and should be protected from damage to the cutting edges. If transported wet there is an increased chance of staining or corrosion. Prolonged storage in disinfectant solutions may result in corrosion and should be avoided.
