FIELD: manufacture of hot rolled super-thin strip of continuously cast billet. ^ SUBSTANCE: method that is realized due to using cooling system comprises steps of preliminary reduction of billet just after continuous casting process; induction heating for sustaining temperature of intermediate strip in temperature range 100 - 1400°C; final rolling till thickness value at least equal to 0.4 mm during no more than six passes while keeping controlled temperature at outlet of last stand of finish rolling mill higher than 750°C; cooling strip between last stand of finish rolling mill for time period normalized by diagram (time-temperature- conversion) for producing steel of desired quality and strip thickness. Apparatus for performing the method includes equipment necessary for such method and process control system having master-system and six additional peripheral subsystems. ^ EFFECT: possibility for producing strip with controlled properties of metal in coils of any mass values. ^ 24 cl, 5 dwg, 1 tbl |
