Abstract
Inventia se refera la un procedeu si la un amestec pentru îmbinarea, prin sudare aluminotermica a elementelor de cale ferata, de exemplu, a unei încrucisari, turnata din otel manganos si o sina de otel carbon. Procedeul consta din utilizarea unei sudari aluminotermice, la care topitura este austenitica, iar zona de îmbinare, dinspre capatul elementului din otel manganos, este supusa unei raciri mai intense fata de zona îmbinarii dinspre capatul elementului din otel carbon. Amestecul utilizat care formeaza topirura austenica are un continut de carbon mai mic de 0,2 % un echivalent de ncihel cuprins între 13 si 35 % si un echivalent de crom cuprins între 8 si 25 %.The invention relates to a process and to a mixture for joining, by alumino-thermic welding of the railway elements, for example, a cross-section, cast from manganese steel and a carbon steel track. The process consists in the use of an alumino-thermic welding, in which the melt is austenitic, and the engagement zone, from the end of the manganese steel element, is subjected to a more intense cooling than the region of the joint from the end of the carbon steel element. The mixture used to form the austenitic melt has a carbon content of less than 0.2%, an equivalent of 13 to 35% and a chromium equivalent of 8 to 25%.
