Hydraulic descaling of wire coils during pickling program

Popis výsledku v původním jazyce

An oxide layer is formed on stainless steel wires during the heat treatment process. To remove the layer of scale, the pickling program is used. The wires are treated in coil that is about 1.3 m in diameter. One pass through the pickling program does not result in a scale-free and rust-free surface for all steel grades and the coil has to go through the pickling program again. This results in unwanted double passages that increase the treatment price significantly. Hydraulic descaling of the whole wire coil was inserted into the pickling program to reduce the number of double passages and prolong the life time of pickling baths. This paper presents a study of descaling efficiency for long distances in free space and through wires. Impact pressure distribution measurements are coupled with descaling of wires. Scales on the wire samples were analyzed using optical as well as scanning electron microscopy in combination with energy dispersive x-ray spectroscopy for element analysis before and after descal
