We manufacture shear blades up to 2000mm(78.74 inches) in length for cutting sheet steel etc.
Steel-making by medium frequency furnaces
Steel-making by medium frequency furnacesSteel-making begins from the start of this century
in Jinhai Company. So the company can meet special requirements for materials. In order to
guarantee the quality, Jinhai company imported spectrometer from Germany and is equipped
with various tester, such as tensile tester, impact testing machine, metallography analyzer
and so on.
Electro slag remelting
The largest ingot can reach 3 tons in Jinhai 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 micro-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
Forging steel
Forging process can trance to 1990s in Jinhai company. The largest electro-hydraulic hammer
is 4.5 ton. And more than 6 skilled technicians work here. After forging the inside
microstructure becomes much closer and the metal grain size becomes much smaller. It can
elevate the characteristics and quality of the knife ensuring a longer life of the knife.
Rough processing
No less than 40 sets of processing equipment in the rough processing workshop of Jinhai
company, including lathe, milling machine, planer, drill machine etc. Skilled workers are
employed in its rough processing workshop.
Heat treatment
Jinhai company has independent workshop for heat treatment. Couples of skilled technicians
work here. Actually, all blades(thickness less than100MM)can be fully hardened. Thus, the
blades can be used after repairing until the size reached the minimum design dimension.
Finishing processing
Jinhai 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 5800mm in length and slitting knives with
1400mm in outside diameter.
Testing
Various testers are put to use for testing its products in Jinhai 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 products has a unique tracking number.
Thus it is easy to trace back anytime.
