Circular metal slitting slitter knife 

Products showing :

Products description:

1.Slitting cutting blades  are made of high qualified tool steel and high alloy steel including G1,G2,6CrW2Si,Cr12Mov,D2,SKD61 etc.

2.Most of our blades are used in steel industry .

3.Some material can work under high temperature .

Production process 

A. 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 .

B.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 micro-segregations ) are significantly reduced .

The ESR remelted material improve following mechanical characteristics :

   1)  Improved toughness due to increased homogeneity and isotropy

   2 ) Improved creep resistance properties

   3)Best fatigue strength and tenacity properties as well as outstanding tensile strength
   Improved purity

C.Forging steel

The largest electro-hydraulic hammer is 4.5 ton .

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 .

D.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 .

E.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 .

F.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 knifes with 1300mm in outside diameter.

G.Testing 

Various testers are put into use for testing its procucts in our company .

They are including tensile testers,impact testing machine ,metallograohy analyzer ,harmless flaw detector ,magnetic powder inspection ,hardness tester ,Caliper rule,microcalliper,etc.

Testing is carried our after each step .And every product has a unique tracking number .Thus it is easy to trace back anytime .

Products packages:

1.Anti-rusted oil plastic bag packed inside 

2.Srong wooden cases packed outside :

3.Delivery time:

The products are in stock within 10 days ,if blades need to produce around 15-35 days .
