Steel-making by medium frequency furnace
Our company can meet special requirements for materials . In order to guarantee the quality ,the company imported the spectrometer from Germany and is equipped with various testers,such as tensile tester,impact testing machine,metallography analyzer and so on .
Â
Electro slag remelting
The largest ingot can reach 3 tons in our company .The ingot obtained by this remelting/refining process is very homogeneous and free of internal defects . The segregation of the ingot (called macro-segregations ) are substantially eliminated and the segregations of crystals (called macro-segregations ) are significantly reduced .
The ESR remelted material improve following mechanical characteristics :
  Improved toughness due to increased homogeneity and isotropy
  Improved creep resistance properties
  Best fatigue strength and tenacity properties as well as outstanding tensile strength
  Improved purity
Â
Forging steel
The largest electro-hydraulic hammer is 4.5 ton .And more than 6 skilled technicians work for us .After forging ,the inside microstructure becomes much closer and the metal grain size becomes much smaller . It can evevate the characteristics and quality of the knife ensuring a longer life .
Â
Rough processing
No less than 40sets of processing equipment in the rough processing workshop of our company , including lathe ,milling machine , planer , drill machine etc. Skilled workers are employed in its rough processing workshop .
Â
Heat treatment
Our company has independent workshop for heat treatment . Couples of skilled technicians work here . Actually , most blades ( thickness ≤100mm) can be fully hardened . Thus ,the blades can be used after repairing until the size reached the minimum design dimension .
Â
Finishing
Our company has more than 35 sets of processing equipment including internal grinder , external grinder , surface grinder ,CNC grinder ,electric spark CNC wire-cut etc. The company can produce the shearing blades with 5500mm in length and slitting knives with 1300mm in outside diameter .
Â
Testing
Various testers are put to use for testing its products in our company . They are including tensile tester , impact testing machine , metallography analyzer , harmless flaw detector , magnetic powder inspection , hardness tester , caliper rule , microcalliper , etc . Testing is carried out after each step . And every product has a unique track number . Thus it is easy to trace back anytime
