Electro slag remelting:

The largest ingot can reach 3 tons in Senda 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

Advantage:

1. Different materials of flying shear knife can work stably under 1100 Centigrade.

2. Advanced vacuum heat treatment ensure the hardness and wear-resistance.

Application of the Hot crop shear knife for cutting iron bars:

1. Deform the steel rods under high temperature, max reach 1100 degrees.

Procedure for the production of hot crop shear knife: 

Steel-choosing~~Blanking ~~Forging~~Rough Processing ~~Heat treatment ~~Finishing~~Testing~~Pakaging
