4 TYPICAL PROCESS: TURULENCE PICKLING LINE Turbulent pickling Series 664/665 flat jet nozzles with 45 or 60 spray angle and dovetail connection generate high turbulence. The automatic selfadjusting orientation of the flat jet ensures optimum alignment and easy maintenance. Also flat jet nozzles series 62/625 with a male thread connection fulfill the job of generating turbulence. 4

5 Rinsing Series 686 tongue-type flat jet nozzles with 90 or 40 spray angle offer a powerful spray. The large free cross sections minimize the risk of clogging. 5

6 WHAT YOU SHOULD KEEP IN MIND WHEN PLANNING Nozzle selection a Material b Turbulence pickling c Rinsing d low-off e Spray headers f Maintenance a Material The basis for all other following steps is to select an adequate material for the nozzles and the accessories. Also the life-time of these components depends on the material and the atmosphere they are used in. As the resistance of the material depends very much on the specific operation conditions (such as temperature, acid concentration, residence time, mechanical stress, etc.) the table shown below could only give a rough and general recoendation. b Turbulence pickling In the turbulence pickling section the nozzles have to offer a homogeneous liquid distribution over the entire material width. At the same time they are responsible for creating turbulence in the pickling liquid. The nozzle sprays have to force continuously the heated acid into the cracks of the scale layer on the strip. This is most important for an effective pickling and helps to accelerate the chemical process which will lead to an optimum capacity of the entire line. Flat jet nozzles could fulfill these demands in perfection. Whenever possible a staggered nozzle arrangement (see adjoining graphic) should be preferred to avoid any linear spray pattern on the strip. Furthermore, optimal overlapping of the adjacent sprays is a fundamental factor when defining the nozzle arrangement. Lechler will be pleased to assist you. Liquid distribution measurement (standard parabolic liquid distribution of a flat jet nozzle) Chemical Resistance Code 7 / Y 5E 53 Material AISI 36Ti / AISI 36L PVDF PP Acetic Acid C2H4O2 only at room temperature Caustic Soda NaOH only low concentration and only at room temperature - Formic Acid CH2O2 only at room temperature only at room temperature Hydrochloric Acid HCl - Hydrofluoric Acid HF - max C (depending on concentration) only low concentration and only at room temperature Hydroxypropionic Acid C3H6O3 only at room temperature only at room temperature only at room temperature Nitric Acid HNO3 only low concentration max.concentration 70% - Phosphoric Acid H3PO4 max.concentration 0% if temperature higher than room temperature only low concentration and only at room temperature Sulfuric Acid H2SO4 only low concentration (max.7,5%) and only at room temperature only low concentration and only at room temperature This table is only a rough recoendation. It is not to be considered as any kind of guarantee. The resistance in detail is highly dependent on the combination of thermal, mechanical and chemical load as well as on the exact material composition and the duration of the mentioned loads. 6

7 c Rinsing The rinsing section is absolutely decisive as it has to stop the chemical reaction and prevent over-pickling. An effective rinsing by an appropriate nozzle installation has a significant influence to the optimum result. Areas with a lower rinsing water density or even gaps in between the sprays could lead to severe quality issues. Therefore, an adequate nozzle selection and arrangement with an even liquid distribution is as important as good maintenance work. Example of a staggered nozzle arrangement Top side Liquid level [%] Position Simulation of liquid distribution d low-off After leaving the rinsing section the water should be removed from the strip. Typically, nozzles for compressed air could manage this job. Especially, at the edges of the strip remaining rinsing water droplets have to be blown off. The multi-channel Whisperblast nozzles are especially designed to offer highest performance. Installed properly they are most effective. The air nozzles must cover the full range of the possible strip edges. Therefore, minimum and maximum strip width as well as the accuracy of the horizontal strip guidance has to be taken into account. Strip edge blow-off with multi-channel nozzles for compressed air 7

8 WHAT YOU SHOULD KEEP IN MIND WHEN PLANNING e Spray Headers Precise nozzle sprays need to be installed accurately on precise spray headers. Complete spray headers could be manufactured by Lechler according to your drawings. Lechler could produce headers in material stainless steel as well as in plastics according to your specifications. Spray headers made of PVDF Spray header made of stainless steel Spray headers equipped with tongue type nozzles 8

9 f Maintenance As the nozzles and accessories are exposed to the rough operation conditions their state should be checked regularly. Especially the nozzles themselves are subject to wear, clogging or damage. A worn out nozzle could not fulfill the high functional demand anymore. An uneven overall liquid distribution and hence a non-uniform product surface could be the result. Worn out or clogged nozzles must be replaced by new ones in regular intervals to ensure optimum operation.

39 Tangential Nozzles Series Very homogeneous and stable hollow cone spray pattern. Not prone to clogging due to tangential design. Applications: Acid regeneration Material: Aluminium oxide Material: Silicon carbide 5 Typical dimensions (details on request) For the acid regeneration a very precise spray pattern even at low flow rates is required. The nozzles are fitted in a plate with multiple borings allowing the flow to pass through to the nozzles and to position them correctly. Special materials such as sintered silicon carbide or aluminium oxide are used for the nozzles to prolong the life-time in this demanding atmosphere. Please contact Lechler for available flow rates and spray angles. Schematic view of reactor 39

40 OPTIMIZED STRIP COOLING IN COLD CONTINUOUS ANNEALING AND PICKLING LINES (CAPL) WITH LECHLER AIR MIST SPRAY COOLING HEADERS It is in the cold continuous annealing and pickling line where the treatment of the strip is performed, providing the metallurgical structure of the stainless steel. At temperatures between 800 C and 200 C the recrystalisation takes place in the furnace before the strip is cooled from top and bottom by means of air blowing, conventional water spray cooling and air-mist spray cooling. Often it is a combination of all three methods. Varying steel grades and line speeds require specific cooling rates to avoid carbide precipitation at grain boundaries. The special Lechler AirMist Cooling Header design is providing exactly that. The : 0 water control ratio (turn down ratio) allows a precise setting with perfect spray patterns from min. to max. line speeds. The large spray overlaps ensure a uniform cooling over the entire strip width for an optimal thermal homogeneity across the strip.
