Product Description

TUNGSTEN CARBIDE SEAL RING

Mechanical seal ring are used to seal the clearance between the rotating shaft and the stationary housing in equipment such as pumps and mixers, so that liquid can not leak out through this clearance. Tungsten carbide is the most excellent seal face material in the seal material world.One of main reasons for using Tungsten Carbide is the additional wear resistance that can be achieved in both moving and static parts.This is particular the case in serve service conditions, such as high temperature,and high levels of corrosion and abrasion. It is widely used in Oil Refineries, petrochemical industries, Fertilizer Plants,Petrochemical plants, Pharmaceutical industries.

With high strength, toughness, wear and corrosion resistance and excellent heat-conducting property, hard alloy sealing rings provided by Zhuzhou huijin carbide are mainly applied in some places with terrible environment. Zhuzhou Huijin carbide designs different marks according to different environment; the products can be divided into inlaid hard alloy stationary ring and solid carbide stationary ring according to the structure, such as different types with/without anti-rotating pins. Refer to product catalog for details. The ordinary marks of hard alloy sealing rings produced by the company as follows:

Carbide production

The productionprocess of powder-metallurgical products basically includes the four steps of powder preparation, forming, sintering andfinishing.

Tungsten carbide production
The APT (ammonium para-tungstate) is calcined into tungsten oxide under high te-mperature. Subsequently the oxide is reduced to tungsten metal in a hydrogen atmosphere. The metal powder is then mixed with carbon and carburised under
inert atmosphere at high temperatures. The production parameters are decisive for the WC grain size in the sintered carbide.

Powder preparation
The tungsten carbide is intensely mixed with the binder metal
cobalt, nickel or iron, various grain growth inhibitors and materials,
which promote compaction, by wet grinding so that a
homogeneous suspension is created. Afterwards, the suspension
is dried in a spray tower to produce a granulate with good
flow characteristics. This granulate represents the basis for all
forming processes.

Metal forming
The objective of the forming process is to obtain a near net
shape sample. Pressing is normally carried out at room temperature
with pressures reaching up to several tons per square
centimetre.
There are several ways of pressing blanks:
During isostatic cold pressing the powder is filled into an elastic
flexible hose and pressed into a compacted form through
high liquid pressure. The powder blocks which are produced
in this way can then be processed mechanically. All common
machining methods like milling, cutting, drilling or turning may
be applied.
In uniaxial pressing the pressing tool consists of a die and an
upper and a lower punch. The carbide powder is filled into the
die and then compacted to create the so called green carbide,
which is ejected from the pressing die.
Extrusion pressing is mainly used to produce rectangular bar
or cylindrical rod, with or without axial hole(s). A plasticiser is
added to the powder. The resulting paste is pressed through
an extrusion nozzle. Before sintering, the plasticiser must be
evaporated in special drying furnaces.
Metal Injection Moulding (MIM) is a process used to produce
more complex forms which cannot be produced by direct
pressing. The paste preparation is similar to the extrusion
process.

Sintering process
The sintering process converts the blank into a homogeneous
and dense carbide with a high level of hardness. The material
is sintered at temperatures between 1,300 and 1,500 °C
(liquid phase sintering) and sometimes also at high pressure
(up to 100 bar). The volume is reduced by up to 50 % during
this process.

Finishing
In order to achieve the final requirements of surface finish, tolerances,
etc. carbide parts can be subjected to a series of finishing
processes such as grinding, spark erosion and coating.
