DESIGN OF COOLING SYSTEMS FOR GROOVED ROLLS

Original language description

This article deals with the design of cooling systems for grooved rolls. The purpose is to extend the life of rolls by minimizing negative thermal stress during the rolling process. Specifically, this paper presents a design for a cooling section for a U-caliber roll. This article first describes an experimental stand which was built to obtain the boundary conditions (Heat Transfer Coefficients) on the surface of rolls. The laboratory stand consisted of a rotary cylinder and a cooling section. A set of thermocouples was installed in the cylinder. HTCs are evaluated from the temperature record from the cooling experiments, and used to solve a 2D inverse heat conduction problem. The influence of water pressure and various geometric configurations on cooling intensity were studied. The second part of this article deals with the design of an optimal cooling configuration to reduce thermal stress in critical points of the grooved roll. The temperature-deformation FEM model was used to express the state of stress inside the roll. The HTCs obtained from the first part were used as boundary conditions. The cooling effect of the proposed cooling configuration was verified experimentally. A stainless steel sample with U-shaped groove and instruments was made for this purpose. The size and dimension of the sample was designed on a realistic caliber scale.
