Abstract

MOLDE PARA A SOLDAGEM ALUMINO-TéRMICA DE TRILHOS DE FERROVIAS, EM QUE PELO MENOS UM ESTá GASTO. A presente invenção refere-se a um molde para a soldagem alumino-térmica de trilhos ferroviários. O revestimento compressível (58) usado para vedar a matriz de moldagem em relação a vazamentos do metal de solda no estado líquido, é limitado às partes das superfícies de contato (52) das partes (19) do molde sobre os trilhos a serem soldados, correspondendo ao fundo, ás laterais e ao topo do pé, às laterais da alma do trilho e abaixo da parte superior O material rígido refratário das partes (19) é exposto nas partes (67, 71) das superfícies de contato correspondentes ás laterais e ao topo da parte superior e adequado para ser removido seletivamente do mesmo. Isso torna fácil adaptar o molde a trilhos com graus diferentes de desgaste.
