Main technical parameters: 1, the surface hardness of the toothed flow HRC 38 - 42; Impact viscosity after heat treatment of toothed body ≥ 49J/cm2; 3, alloy head and tooth head weld seams are filled with welding material more than 80%, the seam area and welding material connection surface have no cracks; 4. resistance to the displacement of the solder seam between the toothed housing and the hard alloy ≥ 180 MPa; 5, transverse teeth each part of the surface smooth, no cracks, scars, slag, freckles, hair defects, the surface has been treated with anti-corrosion; The main dimensions and tolerances meet the standard requirements. Performance Characteristics: • High fatigue limit and repeated impact resistance, high shear strength, good low-temperature impact viscosity • Long cycle of use of geared section, effectively reducing equipment load and reducing sparks and dust, reducing service downtime, increase load · Small cutting resistance, increase the traction speed of coal machine, reduce equipment damage caused by wear; Effectively reduces longitudinal impact and traction, increases walking speed and reduces energy consumption applied to the transverse tooth during walking • Teeth are designed according to standard assembly requirements, using cold temperature precision forging technology, the crystals of the core tissue are thinner, mechanical characteristics are more perfect, geometric consistency is more uniform • Standard size of shoulder bracket for maximum protection of toothed seat and bushing • Alloy head using tungsten carbide solid alloy, high temperature wear resistance is superior • Advanced welding process, so that the alloy head is not easy to fall off • The use of such laser coating technology as laser coating can greatly improve the wear resistance of the toothed section, effectively extend the product use cycle · the alloy head and steel toothed body are alternately evenly worn out, so that the toothed tip for a long time maintains the sharp state and scope of the use cycle: mainly used in integrated excavator, long-arm complex coal machine, continuous coal machine, excavator anchor machine, washing crusher, etc. D. (can be produced a full range of sample toothed products supporting all the above equipment).
