Tungsten Copper Guide Plate

Tungsten copper composite material has high hardness, high strength, high melting point and excellent wear and corrosion resistance, which has been widely used in many high temperature and corrosive material fields. As the key part of rolling mill, tungsten copper guide plate plays an important role in passing in and out of the groove, which performance and service life has an great effect on the efficiency directly. When the guide plate works, contact with hot rolling and doing a relatively high speed movement, the main failure modes include high temperature oxidation wear and fatigue spalling. So it requires the materials for guide plate not only has good high-temperature oxidation resistance, high temperature wear resistance, but also has excellent toughness and impact resistance, which all suits the characteristics of tungsten copper composite materials.

Compared with alloy steel guide plate, tungsten copper plate guide and guard by casting penetration surface alloying alloy powder previously fixed at a specific location and casting so that the surface has a special microstructure and properties of wear-resistant, heat-resistant high-alloy layer and the substrate itself has a good toughness to withstand impact. Adopt new non-binder alloy powder infiltration process, to overcome the current general casting penetration surface alloying process stability is poor, poor surface quality, combined with surface layer or infiltration casting porosity and other shortcomings easily appears; using a special alloy powder embedded processing and packaging reasonable alloy powder ratio, thus ensuring the casting penetration surface alloyed layer and the substrate is a good combination; substrate itself has sufficient strength and toughness, combined with the antioxidant properties of the alloy layer and anti-wear properties of high temperature. Overall, surface alloying process has many advantages, such as simple equipment, short production cycle, low production cost, the parts not easily deformed and good thickness of the treated layer.
