Structure of a Strip Degreaser (e.g. for a strip annealing line)

Entfettungsteil mit Bürstmaschine und Spülen A combination of spray degreasing and brush degreasing is generally used to remove rolling oil from the strip surface. Alkaline washing lye is sprayed on both sides of the strip. Squeegee rollers are positioned behind the degreaser in order to keep the fluid exchange between the individual parts of the plant as low as possible. The length of the degreasing section and the exposure time of the washing lye depends on strip speed. The rollers must always be operated synchronously to the strip run. The nozzles of the spray degreaser are operated at medium pressure. For this purpose, the washing lye must be so that disturbing foam formation is avoided. The degreasing process is usually supported mechanically by a wash-brushing-machine. The brush rollers are equipped with relatively soft nylon bristles in order to break-up the rolling lubricant layer on the strip surface and to remove any grease and dirt. Afterwards, the strip passes through at least two, preferably three rinsing chambers and through one strip dryer, separated again by squeegee rollers, before it enters the furnace.
