iron mill scale in electrode making

What exactly is Mill Scale and what is done about it

Mill scale can be used in other iron ore preparation for steel making but it may require crushing and grinding it to very specific sizes and too expensive or it can be briquetted and used directly. If it is used directly the further preparation and processes to use it would have to be scrutinized to ensure that it would be efficient and economic to do so.

These elements work together as deoxidizers to help weld through certain levels of dirt, debris or mill scale that can be commonly found on structural steel applications. E4918 stick electrodes also offer good arc starts and restarts, which help eliminate issues like porosity at the start or end of the weld.

SIPS2015

The steelmaking industry in semi-integrated plants produces steel from ferrous scrap, using electric arc furnaces (EAF). Besides steel, this operation generates several solid wastes or by-products with low value. Among these wastes, there are some with high iron content, mainly composed of iron oxides, e.g mill scale and EAF dust, which increase the interest on recycling them in the plant ...

Mill Scale Uses and Applications

A. Mill scale is oxides of iron and alloying elements present in steel. Obviously, it is a rich source of iron. Most of the steel plants recycle mill scale through sintering or pelletization. However, a value-added utilization of mill scale is in steel making after converting

Mill scale

Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills. Mill scale is bluish-black in color. It is usually less than 0.1 mm (0.0039 in) thick, and initially adheres to the steel surface and protects it from atmospheric corrosion provided no break occurs in this coating.
