Slag Dart Machine For Steel Making

Supplier From China
Oct-27-18

Features
An integration of both mechanical and electric.
The operating design is totally accord to ergonomic principles.
Capable of effective measures;adaptive to high temperatures and harsh environmental conditions, efficient slag blocking, accurate positioning and operational reliability.
Precise position control and error control guarantees the hit accuracy of the dart rod.
Automatic and manual features are set to cope with accidents in case of emergency treatment.
Cantilever rod with an independent air cooling system.
Description
The slag dart dispatching machine is a special device used for optimizing the production of BOF steelmaking. It improves the quality of the steel by reducing the slag mixed into the ladle and reducing the loss of ferroalloy.

When the converter releases the molten steel, the device puts a slag dart into the tap hole to prevent the liquid slag mix into the ladle.

After the Slag Dart Machine completes the whole process, there is a significant reduction of slag mixed in the ladle, and by reducing the alloy consumption, steelmaking process along with economic advantage is highly improved.

Stainless Steel Mill Scale

$220.00
MOQ: 100  
Supplier From Southampton, United Kingdom
 
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.

Commodity: Synthetic Cryolite
Formula: Na3AlF6
M.W.: 209.95

Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

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 21% of the products, their biological effects better. This unique high-tech companies use technology to make our products crystallization, high purity.
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 particles MDCP in the animals stay in the stomach longer and more conducive to the absorption of calcium phosphate, the product produced by micro-particles MDCP form, without any chemical binder.
