Abstract
Inventia se refera la un procedeu de realizare a sîrmei de molibden, rezistenta la temperaturi înalte, destinate în special fabricarii lampilor electrice cu incandescenta, unde este utilizata ca dorn de înfasurare a filamentelor de wolfram. Procedeul, conform inventiei, consta în aceea ca sîrma de molibdem trefilata la fi 0,6 mm si curatatp prin electroliza în solutie apoasa de hidroxid de sodiu, este supusa unei recoaceri de omogenizare la o temperatura cuprinsa între 1000 si 1020 degree C la trecerea printr-un cuptor tubular cu o viteza de 4m/min, timpul de recoacere fiind stabilit în functie de gradul de ecruisare a sîrmei, pentru sîrmele de molibden trefilate la fi 0,3 mm, recoacerea de omogenizare a structurii se realizeaza la temperaturi de 950...965 degree C cu o viteza de 8m/min.
