Steel-making by medium frequency furnaces

Steel-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.

Some advanced epuipment

1.Electroslag furnace for steel-making

2.Electro-hydraulic hammer(The largest one is 4.5 ton)

3.Spectrometer imported from Germany(It can analyse chemical composition very fast)

Inside packing (Applied with anti-rust oil and then packed in plastic bag)

Outside packing (Strong plywood case)

Jinhai company has one independent R&D department which is fully equipped with experimental and testing facilities. Until now, we have developed some high alloy steel, like HMB, HMK etc.They are new materials independently developed by our company and excellent in high intensity, high hardness, high wear resistance, high toughness, high hot hardness and so on. They can be used in both cold and hot shearing and have been rewarded the national invention patens. The life of blades and knives made of HMB and HMK is 2-3 times longer.
