Abstract
Μία μέθοδος και συσκευή για τον προσδιορισμό της κρίσιμης θερμοκρασίας στην οποία σχηματίζεται μπαινίτης από ένα χάλυβα χαμηλής περιεκτικότητας σε άνθρακα, και για το σχηματισμό ενός υλικού χάλυβα με ένα προκαθορισμένο εκατοστιαίο ποσοστό μπαινίτη. Η θερμοκρασία του χάλυβα χαμηλής περιεκτικότητας σε άνθρακα ανυψώνεται σε μία θερμοκρασία επάνω από την κρίσιμη θερμοκρασία στην οποία σχηματίζεται ο μπαινίτης. Η θερμοκρασία μετά ανέρχεται στην κρίσιμη θερμοκρασία και διατηρείται στο επίπεδο εκείνο ώσπου ένα προκαθορισμένο εκατοστιαίο ποσοστό της μικροδομής του χάλυβα να μεταβληθεί σε μπαινίτη. Μία νέα αλυσίδα αντλία 16 κοινολογείται για την διατήρηση του χάλυβα σε ένα επιλεγμένο οριζόντιο επίπεδο θερμοκρασίας. (του διαγράμματος χρόνου θερμοκρασίας σ.τ.μ.).ω
