Product Description

Description of cementd carbide roll ring:

Characteristics of the carbide roll ring

High hardness and good wear resistance: Hardness at room temperature can reach HRA78-89, good red hardness under high temperature, 600C over high-speed steel, 1000C over the room temperature of carbon steel.

High mechanical strength: the compressive strength of up to 6000MN/m2, 900C, the bending strength can still above 1000MN/m2

High modulus of elasticity: good rigidity at room temperature, no significant plastic deformation, Young’s modulus is 2-3 times that of steel.

Corrosion resistance and good oxidation resistance: acid alkali, 600-800C without significant oxidation.

The linear expansion coefficient is small: in the range of 20 to 400C for steel 0.35 to 0.65.

Conductivity: Similar with iron and ferroalloy.

The thermal conductivity of steel 1/2, copper 1/3

High density: carbide roll ring density is much larger than the steel used in rolling the field of carbide roll ring binder content of 6 percent to 30 percent, the density is between 12.6-14.8 g/cm3a

Tungsten Carbide Rolls (2) - Application

Application of tungsten carbide rolls

Within the metalworking industry, tungsten carbide rolls are used in a wide variety of applications, including.

Hot Rolling

· Wire rod finishing mills

· Wire rod intermediate mills

· Cantilevered stand mills for rounds and shapes

· Merchant bar mills - rounds, rebar, shapes

· Pinch rolls - guide rolls

· Roller entry guides

Cold Rolling

· Cluster mill work rolls

· 2-Hi narrow strip mills

· Wire-flattening and forming mills

· ERW tube mills

· Turks heads

Table 2 shows some selected applications with illustration of some performance data. Some early applications are also listed in the table.

Mills today are equipped with composite rolls utilizing tungsten carbide rolling rings. The rings are fixed onto roll mandrels so as to resist rolling torque while avoiding detrimental tensile stresses.

For rolling mills equipped with modern cantilevered intermediate stands, tungsten carbide has developed as the material of choice in many rolling mills throughout the world. Both solid tungsten carbide rolls and composite tungsten carbide rolls have enabled users to limit roll changes in these stands to as few as one for every four of the "8 in" rolls immediately after them.

Most finish blocks (e.g. No-Twist mills) are equipped with pinch rolls at the entrance to the laying head. At rolling speeds approaching 20,000 ft/min (100 m/s), tungsten carbide pinch rolls are preferred over other materials in this application.

1.Tungsten carbide rolls can last up to 50 times longer than conventional, hardened tool steel rolls

2.Tungsten carbide increases the tooling life before regrinding, lasting up to 10 times longer than conventional, hardened tool steel rolls

3.Guaranteed product performance

4.Solves excess wear problems on any roll section of the mill

5.Fewer changeovers, due to excessive wear on hardened tool steel rolls

6.Holds tighter tolerances on tube and pipe

7.Tungsten carbide rolls should be considered, when high footage/tonnage is required from any one particular size

8.Eliminates pick-up to give tube and pipe a better surface finish

9.Rolls can be solid carbide on smaller mills or carbide-inserted for larger rolls
