- the invention relates to a device for cooling conveyed on a conveyor line metal strips or sheets according to the preamble of claim 1 or 4, and a corresponding method according to the preamble of claim 1 1, 13 and 15.
- mechanical properties are influenced in a variety of ways.
- an increase in strength is achieved (solid solution hardening).
- the finishing temperature can be lowered to achieve a higher dislocation density (dislocation hardening).
- alloying micro-alloying elements - eg Nb, V or Ti - precipitates are formed, which cause an increase in strength (precipitation hardening).
- the above-mentioned mechanisms have the disadvantage that this adversely affects the toughness of the material produced.
- a fine grain structure (fine grain hardening) has a positive effect on the strength and simultaneously on the toughness properties of the steel materials produced. With a small grain size, the strength and toughness properties of the steel material are improved.
- alloying and / or micro-alloying elements which is known in the operation of cast rolling mills and hot strip mills, suffers from the disadvantage that such an addition is costly and is additionally limited by various conditions.

- ferrite grain size In the production of steel materials, a reduction in (ferrite) grain size generally causes an increase in strength, which is described by the Hall-Petch equation. Hereafter, the increase in strength is inversely proportional to the grain size.
- the cooling rate By increasing the cooling rate, a reduction in the grain size of the end product is achieved, so that the production of higher-strength materials is possible with an increase in the cooling.
- the toughness properties of the final product are enhanced by a finer ferrite grain, as described by the Cottrell-Petch relationship.
