Abstract

Sposób wytwarzania walcówki lub drutu o wielofazowej strukturze typu TRIP ze stali niskowęglowej i średniowęglowej zawierającej węgiel w ilości od 0,09 do 0,4% wag., zwłaszcza od 0,09 do 0,19% wag., mangan w ilości od 0,2 do 1,8% wag., zwłaszcza od 1,4 do 1,5% wag., oraz krzem w ilości od 0,2 do 1,5% wag., zwłaszcza od 0,5 do 0,8% wag., przy czym sposób obejmuje następujące etapy: materiał (1) w postaci walcówki zwłaszcza drutu, ze stali niskowęglowej lub średniowęglowej rozwija się oraz prostuje w prostownicy rolkowej, następnie nagrzewa się, a na koniec chłodzi się, po czym ciągnie się go rolkami i nawija. Sposób charakteryzuje się tym że etap nagrzewania obejmuje dwa podetapy: (a) najpierw materiał (1) nagrzewa się do temperatury w zakresie od 740°C do 850°C i dalej wygrzewa się go w tym samym zakresie temperatur przez 45 do 240 s, (b) następnie nagrzany materiał (1) chłodzi się do temperatury w zakresie od 350°C do 450°C i dalej wygrzewa się go w tym samym zakresie temperatur przez 45 do 240 s. Zgłoszenie obejmuje także układ do realizacji ww. sposobu.A method for producing a wire rod or wire with a multi-phase TRIP structure from low- and medium-carbon steel containing carbon in an amount of 0.09 to 0.4% by weight, especially 0.09 to 0.19% by weight, manganese in an amount of 0. 2 to 1.8% by weight, in particular 1.4 to 1.5% by weight, and silicon in an amount of 0.2 to 1.5% by weight, in particular 0.5 to 0.8% by weight. the method comprising the following steps: the material (1) in the form of wire rod, especially wire, of low carbon or medium carbon steel is unwound and straightened in a roller straightener, then heated, and finally cooled, and then drawn with rollers and wound. The method is characterized in that the heating step includes two sub-stages: (a) first, the material (1) is heated to a temperature in the range of 740°C to 850°C and then it is heated in the same temperature range for 45 to 240 s, ( b) then the heated material (1) is cooled to a temperature in the range of 350°C to 450°C and further annealed in the same temperature range for 45 to 240 seconds. way.
