Carbide Cooling Nozzles for Cold and Hot Rolling
Nozzles for roll cooling
Optimum roll cooling in hot and cold rolling mills
During the rolling process in hot and cold mills, heat is generated by mechanical deformation of the rolled parts due to frictional deformation. Effective cooling of the work rolls and support rolls (if necessary) is therefore essential for the forming process to ensure stable roll temperatures as well as efficient heat transfer and heat dissipation. Therefore, the goal is to create uniform, even cooling over the entire roll width with a homogeneous and acceptable heat distribution.
SPP CARBIDE produces cooling nozzles for hot or cold rolling mills. The use of tungsten carbide nozzles with either an integral tungsten carbide or a shell steel core allows for tens of times the failure of normal stainless steel.
Material options: tungsten carbide, high-speed steel, stainless steel, etc.
The basis for efficient and economical roll cooling is the optimal arrangement of nozzles and bars. The most important aspect of rolling is the heat generated by friction and deformation during the rolling attack.
The most important aspect is:
Ensuring consistent and stable roll temperatures around the roll and over the entire roll width
Optimum heat ball generation and minimum temperature difference between the upper and lower work rolls as well as optimum cooling
As a result of the current increase in the thickness of hot strip, there is an increasing demand for mills to roll smaller final sizes, resulting in higher pass depressions on individual mill stands. Such large thickness reductions result in larger contact areas, as well as higher rolling forces, heat generation and higher rolling forces.
These pass arrangements, coupled with the need to roll an increasing number of material cross-sections in a wider range of soft and hard materials, lead to greater challenges in controlling working rolling temperatures and effective heat removal.
Achieving uniform, homogeneous cooling
The ultimate goal is to achieve uniform, homogeneous cooling over the entire roll width. With an optimally designed roll cooling system in perfect condition, several important goals can be achieved:
Maximum heat removal with minimum coolant consumption
Symmetrical temperature distribution on the working rolls
Hot pack control
No temperature difference between upper and lower work rolls
Ensuring that the roll bending system remains in the desired working area by maintaining the height and symmetry of the heat pack.
