Cemented carbide roll ring (also known as tungsten carbide roll ring) is a roll made of tungsten carbide and cobalt by powder metallurgy. There are two types of cemented carbide rolls: integral and combined. Superior performance, stable quality, high machining precision, good wear resistance and high impact resistance. Cemented carbide roll has been widely used in the production of rod, wire rod, deformed steel bar and seamless steel pipe due to its good wear resistance, high temperature red hardness, heat fatigue resistance and high strength, which greatly improves the effective operation rate of the rolling mill. According to the difference of working environment of each stand roll, various kinds of cemented carbide roll rings of different grades have been developed, which are mainly used for finishing rolling block.

Dimensions and Tolerances of tungsten wire: Tungsten wires diameters are generally expressed in terms of inches or mils (thousandths of an inch). For thin wires from. 001 inches up to. 020 inches in diameter, the diameter of the wire is measured by weight per unit length. That is, the weight expressed in mg of a 200 mm length of wire. The standard diameter tolerance is: � 3% of the weight measurement. Closer tolerances are available, depending upon the application for the wire product. Specification: Diameter, mm Difference between 2 feet, mm Inside diameter tolerance, mm Big heater element Small heater element 0.4-3.0 1 0.3 0.4-1.0 1 0.3 0.4-1.3 1 0.3 0.4-1.0 2 1 0.3 0.4-1.0 1 0.3 0.4-1.0 several stranded coils 0.3 Note: Different diameter and length are available for your 99.95% pure stranded tungsten wire. 3. Straightness of tungsten wire: Wire may be finished in the unstraightened or as drawn condition and is controlled to Bango's internal standards, In addition, wire can be straightened via mechanical or heat treating processes. Typically, the measure of the straightness of a tungsten wire is obtained by cutting a ten inch long piece of wire and allowing it to lie on a flat clean surface. The maximum deviation from a straight line along its length is the quantitative measure of its straightness. In general, as the degree of straightness increases, tensile strength decreases. 4. Quality and Finish: Wire is free of scratches, kinks and distortions insofar as they are harmful to the intended end use of the product. Surface finish is supplied in the black, as drawn condition, where drawing lubricants and oxides are retained on the surface, or in the cleaned condition by firing in hydrogen or electrochemical etching. 5.

Tungsten heavy alloys is a kind of alloy made by liquid-phase sintering process with Tungsten as the basic element and Ni, Cu, Fe and other elements added at the same time. Its density is up to 16.6 ~ 19.0g/cm3. It has outstanding physical and mechanical properties such as high density, good strength, low thermal expansion coefficient and good machining performance. Tungsten heavy alloys can be divided into large series: W-Ni-Cu series and W-Ni-Fe series, the former is non-magnetic alloy, the latter is magnetic alloy. W-Ni-Fe series alloys are widely used because of their better mechanical properties than W-Ni-Cu series alloys.

Cemented carbide is the term which refers to sintered composite materials composed of at least one metal carbide constituent. Tungsten Carbide (WC), Titanium Carbide (TiC),Tantalum Carbide (TaC) are common constituents. Our tungsten carbide rods are made of optimum quality raw material WC, which acts as hard phase, and the binder agent Cobalt. With powder metallurgy HIP technology, carbide rods are sintered with homogeneous microstructure including little or even no porosity, to a great extent, increasing the whole performance and properties such as hardness and bending strength. Our HF30U solid rod obtains 93 HRA hardness and at least 4000 MPa transverse rupture strength.
Cemented carbide sleeve adopts raw and auxiliary materials such as primary saturated tungsten carbide, high-purity ultra-fine cobalt powder, precise carbon blending, tilt ball milling, vacuum stirring drying, precision pressing, digital degreasing sintering and pressure sintering personalized post-processing and other advanced powder metallurgy processes.
