Abstract

processo para a soldagem aluminotérmica de trilhos, molde e dispositivo o processo para a soldagem aluminotérmica de trilhos, no qual duas extremidades de trilhos a ser soldadas são circundadas por um molde (1) de soldagem que define uma cavidade de moldagem (10) compreende as etapas de desencadear uma reação aluminotérmica em um cadinho (2), fundir o metal proveniente da reação no molde (1), de forma a encher a cavidade de moldagem (10) a partir da sapata de trilho, após o enchimento da cavidade de moldagem (10), uma etapa de desencadear uma segunda reação aluminotérmica acima do cabeçote de trilho, e de fundir o metal proveniente da segunda reação na cavidade de moldagem (10) na região do cabeçote de trilho. a presente invenção trata também de um molde (1) para a soldagem aluminotérmica de trilhos, adaptado para se encaixar sobre as duas extremidades de trilhos de modo a formar uma cavidade de moldagem (10), o molde (1) compreendendo um orifício de enchimento para verter metal fundido de um cadinho (2); compreendendo pelo menos um tubo de enchimento de molde (15a, 15b) deslocado em relação ao orifício de enchimento e que se estende até a cavidade de moldagem (10) em uma região da sapata do trilho, e um cadinho secundário (4), disposto acima de uma região do cabeçote de trilho e abaixo do orifício de enchimento, de forma a ser alimentado com metal fundido da cavidade de moldagem (10) por um canal secundário (42) acoplado à cavidade de moldagem (10) e ao cadinho secundário (4).
