Tungsten Carbide Inserts Fitting Introduce

Many inserts for mining tools are made of tungsten carbide. Mining and tunneling cutting tools are fitted with tungsten carbide tips so it is called "Button Bits". Only man-made diamond may replace the tungsten carbide buttons when conditions are ideal, but as rock drilling is a tough task, tungsten carbide button bits remain the most used type throughout the world.

Tungsten carbide inserts fitting is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using tungsten carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide. Most modern face mills use carbide inserts, as well as many lathe tools and end mills. In recent decades, though, solid-carbide end mills have also become more commonly used, wherever the application's characteristics make the pros outweigh the cons.

Tungsten Carbide Button Fitting

Tungsten carbide, which is also sometimes referred to as “Heavy Metal”, has a compressive strength much greater than any hard metal or alloy. Because it’s highly resistant to abrasion, it is ideal for use in a variety of wear applications. Tungsten carbide button fitting is machine able and is usually sintered from powdered tungsten and powdered copper, it is a biologically safe, very heavy material. The scrap tungsten carbide button fitting is recyclable and it is typically produced when drilling or machining golf iron weights, gamma collimators, and aircraft elevator balance weights. It is stable nature even in high temperature that maintains the high hardness and high intensity. Especially, the WC-Co carbide performs very well in the machine.

Tungsten Carbide Pellets Fitting Application

Tungsten carbide pellets fitting are used to be welded onto the surface of the tools or work parts to form a hardened wear-resistant layer in order to provide protection against abrasive wear and therefore increase the service life of the tools and work parts. It is cost effective and is widely used in the drilling and manufacturing industry, engineering machinery, metallurgical as well as mining industry etc.

By piling welded, spraying welded to the surface of tools or working parts to form a hardened wear-resistant layer, it can greatly improve the working life of the tools.
Tungsten carbide pellet is commonly used in applications requiring extreme hardness, excellent wear resistance, and ability to withstand impact and shock.

Tungsten Carbide Fitting Physical Properties

Tungsten carbide fitting is high melting, 2,870 °C (5,200 °F), extremely hard (~9 Mohs scale, 1700–2400 Vickers number) with low electrical resistivity (~2×10−7 Ohm·m), comparable with that of some metals.
WC is readily wetted by both molten nickel and cobalt. Investigation of the phase diagram of the W-C-Co system shows that WC and Co form a pseudo binary eutectic. The phase diagram also shows that there are so-called η-carbides with composition (W,Co)6C that can be formed and the fact that these phases are brittle is the reason why control of the carbon content in WC-Co hard metals is important. 

Tungsten Carbide Fitting Chemical Properties

There are two well characterized compounds of tungsten and carbon, WC and tungsten semi carbide, W2C. Both compounds may be present in coatings and the proportions can depend on the coating method.
At high temperatures WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high velocity oxygen fuel (HVOF) and high energy plasma (HEP) methods.
Oxidation of WC starts at 500–600 °C. It is resistant to acids and is only attacked by hydrofluoric acid/nitric acid (HF/HNO3) mixtures above room temperature. It reacts with fluorine gas at room temperature and chlorine above 400 °C (752 °F) and is uncreative to dry H2 up to its melting point. WC dissolves readily in diluted hydrogen peroxide.

Application of the advantages and disadvantages of the composite cemented carbide roller in the wire rod mill

Cemented carbide roller rings with high hardness, good abrasion resistance on the wire rod mill reflects the following advantages:

(1) improve the quality of steel products, the steel surface quality and tolerances been completely resolved, negative deviation control is very precise;
(2) reduce to change the tank, the roll changing times and downtime, and increase mill capacity utilization and production, the mill at the same time create greater economic benefits;
(3) to reduce the rejection rate, reduce the labor intensity of production workshop;
(4) reduce production costs, increasing efficiency of enterprises;
(5) in favor of endless rolling technology applications.

The disadvantages are: cemented carbide roller rings high hardness, brittleness, high sensitivity to crack, resulting in the maintenance more difficult, in the use of cooling water requirements, and can not withstand thermal shock, otherwise easily lead to destructive accidents. 

Composite Cemented Carbide Roll Pros & Cons - part2

Cemented carbide roller cooling water during use is an extremely important means to better cooling conditions, i.e. the cemented carbide roller rolling groove, the higher the tonnage, roll on the contrary is easy to burst. So, in the rolling process, each production shift every 4 hour check whether the mobile pipe cooling water pipe nozzle is blocked, then the car rolling.
Shift changes, the operator should carefully check the wear of the rolling slot and produce a small crack, such as the above occurs, a member of the dispatch room Quality Supervision should be reported, confirmed and then replace cemented carbide roller rolling groove.
In the rolling process, the roll gap adjustment shall be zero clearance; it can not touch cemented carbide roller rolling.
Sampling room, once the exception of rolled products, shall notify the control room, control room after receiving the notice, should be immediately stopped and checked. In case of cemented carbide roller the parent key block protruding screw loose, there was a slight crack in the rolling groove in need of replacement rolling groove and cemented carbide roller.
ф5-ф8 wire recommends the Single Slot rated rolling tonnage 800-1000 tons. Single Slot rolling tonnage can not be over-tonnage, higher than the imposed or surface micro-cracks will cause the roller ring crack, even if it does not crack can also cause cemented carbide roller ring grinding capacity, resulting in uneconomical.
