Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.

Another innovation is the patented new patented design of the bonded rod, which not only strengthens the strength of the entire heald frame, but also avoids the use of riveting methods that would cause fatigue fracture in the past. The heald frame is also equipped with a cushioning shock absorber, just like the one used on the XLF153 steel heald frame; the new center support design is added and the strength at the 1/3 grip drive point is enhanced, further enhancing the overall Box strength.
The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
As the speed of the loom becomes faster and faster, the original heald frame will emit abnormal noise. Recently, the Belgian CTP accessory company has developed the Hybrid-Power151 steel heald frame to meet the requirements of high-speed looms. The HYbridPower 151 heald frame has exceptional strength and is made of a mixture of lightweight aluminum and high-strength carbon fiber, which is 50% higher than the original design strength, and the frame and the support are flexibly connected with the R-type, which can reduce the pressure of the heald frame.
