Abstract

IN ORDER TO BECOME INDEPENDENT OF THE GEOMETRY OF THE STEEL AND THE STRIP SPEED WHEN PRODUCING DUAL PHASE STEELS (2), WHICH ARE PRODUCED AFTER FINAL ROLLING IN A HOUSING (1) BY MEANS OF SPECIFIC COOLING, WHEREBY A TWO-PHASE GRAIN OF 70 TO 90 % FERRITE AND 30 TO 10 % MARTENSITE IS SET, IT IS PROPOSED ACCORDING TO THE INVENTION TO PERFORM COOLING IN A COOLING STRETCH (6) WITH WATER COOLING STAGES (7) POSITIONED ADJACENT TO EACH OTHER IN THE FORM OF DISPERSED COOLING.(FIG.1).
