Stainless Steel Mill Scale

Stainless Steel Mill Scale

(5.0)
$220
MOQ: 100  
  European Recycle Ltd.
Supplier From Southampton, United Kingdom
Supplier Of Ores & Minerals
 
We are glad to propose 500 MT of stain less steel mill scale.
Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products.

At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.

The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%


From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:

Waste code: 10 02 10

The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers.

Chemical analysis of the material is available on request.

Use
DCP is the feed preparation of raw materials, Animal right to supplement calcium needs. Coarse its products more applicable to the preparation hens, ducks feed, concentrate feed and premix.
Product Nature
Molecular Formula:CaHPO4·2H2O,Molecular weight:172.09,After drying with loose white powdery crystals or granules. Neutral products, the melting acid, water-soluble, hygroscopicity small, heated to 90 around gradually lose water of crystallization.

Product Features
The purity of the product, calcium and phosphorus ratio appropriate to ensure a higher degree of its biological effects. Phosphorus content greater than 18% of the products, due to a small amount of MCP, and its biological effects better.
This unique high-tech companies use technology to make our products crystallization, high purity and its harmful impurities significantly below standards:HG26362000
Drying process advanced products, products with low free water under the premise that the product does not lose crystallization of water, avoid the product in the drying process for the loss of water caused by crystallization of biological effects of the reduction.
Coarse particle DCP in the animals stay in the stomach longer and more conducive to the absorption of calcium phosphate, the product of Micro-particle DCP granulation from mechanical, without any chemical binder.
