Note: 1, with metallurgical ω (Cr 2 O 3) / ω (FeO)> 2 chromium or iron ore concentrates, pyrometallurgical (wet refining of metallic chromium is not limited thereto); ω (SiO 2) ≤ 8% (not limited by smelting high carbon chromium by ore heat method); ω (P) ≤ 0.09%, ω (S) ≤ 0.05%.
2. Chromite or concentrate for refractory materials, ω(SiO 2 )≤10%, ω(CaO)≤2%, ω(FeO)≤14%.
3. For chromite or concentrate for chemical industry, ω(SiO 2 )≤8%, ω(Al 2 O 3 )≤15%.
4, chrome ore with chrome ore, ω (Cr 2 O 3 ) ≥ (10 ~ 20%), ω (SiO 2 ) ≤ 10%.
5, when the required amount of associated chromite selected from PGE reached (0.3 - 0.4) × 10 -6 time, should be assessed.
7. The selection of the minimum mining thickness of the rich ore is 0.5m for the single ore layer and 0.3m for each layer of the double ore layer.

Concrete Spun Pile Mould is a kind of Steel Mould, it is mainly apply to Concrete Spun Pile Plant to produce the Centrifugal Reinforced Technology (PHC ) Concrete Spun Pile, In order to meet customer's requirement to produce high strength PHC concrete pile, Jiangsu Haiheng Company have long term cooperation relationship with Japan spun pile factories for improve the design and technology of mould and use advanced processing equipment, HH's Spun Pile Mould has got the leader market share in the countries like Japan, Vietnam, Indonesia, Malaysia, Thailand, Myanmar, Cambodia etc.
Our Mould Advantages:
1. Mould's tongue-and-groove is designed by the dislocation of upper and lower shell boards, matchboard is plane surface. Slurry does not leak and it is easy to clean mould.
2. The tyre is "T" type forgings. Tyre and its support plate are as whole.
3. Self-developed six-meter press machine of mould inside shell. The inside shell seam extends from two meters to six meters, to minimize welds and mould strength and improve the external appearance of the products
4. Welding process uses CO2 arc shield weld which makes its appearance simple and weld seam neat. Our company cooperated with colleges to introduce [robot welding project".
5. Long lathe, manufacture the whole set mould under fifteen-meter length, greatly increases concentricity of the tyre and flange.
