Abstract

São fornecidos um aparelho para resfriamento de trilho e um método para fabricar um trilho, capaz de fabricar de forma barata um trilho com alta dureza e alta tenacidade. O aparelho (2) para resfriar um trilho, configurado para jatear um meio de resfriamento na porção de cabeça (11) e porção de patim (12) de um trilho (1) em uma faixa de temperatura de austenita para forçadamente resfriar o trilho (1), incluindo: uma primeira unidade de resfriamento (21) incluindo vários primeiros cabeçotes de resfriamento (211a a 211c) configurados para jatear o meio de resfriamento como gás na face superior de cabeça e lado de cabeça da porção de cabeça (11) e primeiras unidades de acionamento (213a a 213c) ) configuradas para movimentar pelo menos um primeiro cabeçote de resfriamento (211a a 211c) dos vários primeiros cabeçotes de resfriamento (211a a 211c) para alterar a distância de jato do meio de resfriamento jateado do primeiro cabeçote de resfriamento (211a a 211c); e uma segunda unidade de resfriamento (22) incluindo um segundo cabeçote de resfriamento (221) configurado para jatear o meio de resfriamento como gás na porção de patim (12).
