Abstract

Procedeul, conform inventiei, de obtinere a tablei, se caracterizeaza prin aceea ca, în scopul reducerii pierderilor în miez, se regleaza cresterea grauntilor în faza de recristalizare secundara, prin normalizarea pentru recristalizarea primara si decarburare la maximum 871 degree C, urmate de aplicarea unei trepte suplimentare de laminare la rece pentru realizarea unei alungiri cu 5...15%, dupa care se aplica stratul refractar separator si se supune tabla tratamentului final, pentru orientare structurala.
