Abstract
MÉTODO DE RESTRIÇÃO DE TRILHO E DISPOSITIVO DE RESTRIÇÃO DE TRILHO. No momento de resfriamento forçado de uma porção superior (11) e de uma porção inferior (13) de um trilho laminado a frio (10), uma posição predeterminada 2 metros de cada uma de ambas as faces terminais do trilho (10) ao longo da direção longitudinal do trilho (10) é definida como uma primeira posição de restrição, uma posição predeterminada 3 a 10 metros a partir da primeira posição de restrição em uma direção ao centro do trilho (10) ao longo da direção longitudinal do trilho (10) é definida como uma segunda posição de restrição, e o deslocamento do trilho (10) em uma direção vertical é restrita na primeira posição de restrição e na segunda posição de restrição por uma força de restrição F (kN) que satisfaz uma condição predeterminada.
