 Easy to use, efficient, flexible, low-cost
Equipment Introduction
 The LDU has higher degassing efficiency because degassing rotors are mounted between the melting furnace and casting machine in the length direction of the launder and the degassing zone is partitioned into several parts for multilevel in-line degassing. The number of rotors depends on the flow rate of molten aluminum.
Equipment Features
High degassing efficiency, above 40%. Adopting multi-zone continuous degassing to increase the contact surface and contact time between bubbles and molten aluminum; adopting the sealed design to maintain an inert headspace above the molten aluminum surface during the entire casting period to prevent more slag to eliminate secondary pollution and improve degassing efficiency.
Low use cost and maintenance frequency. The molten aluminum heating and holding system is removed, reducing consumption. Launders are adopted for degassing, reducing the residual amount of molten aluminum and the loss of metal;low maintenance cost, convenient and fast replacement of launders.
Easy to install. Small size and low weight, space-saving; needless to install the required structure or foundation; installed in the joint positions of launders; a short period of time is required for on-site commissioning, saving production downtime.
 Convenient for alloy conversion. There is no heating device or deep box, so at the end of per casting, most of the degassed metal is made into a product, which can easily clear away residual aluminum liquid in the degassing tank and convenient for the rapid alloy Conversion.
 Easy to operate. No special starting procedure; a simple molten aluminum drainage device; convenient slag removal and simple working conditions.
 Especially suitable for semi-continuous casting lines for the production of cast rods and renewable aluminum ingots. This casting technology is featured by frequent replacement of alloys without a very high dehydrogenation level.

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.
