METHOD OF CONTINUOUS STEEL CASTING Russian patent published in 2010 - IPC B22D11/00 

FIELD: process engineering.

SUBSTANCE: proposed method comprises feeding metal from ladle pot into crystalliser, maintaining crystalliser metal meniscus on one level, drawing ingot from crystalliser and making it reciprocate. Drawing rate id determined by formula V_p = k_v×(A + B)/(A×B)-ΔT×k_z, where k_v is empirical factor equal to 0.15-0.25 m²/min, A is billet thickness, m, B is billet width, m, ΔT is temperature of steel overheating over liquidus temperature, °C, equal to 15-35°C, k_z is empirical factor equal to 0.005-0.015 m/min×° C, swinging angle (A_sw) is varied from ±1.5 to ±4 mm. Frequency N, cycle/min, of crystalliser reciprocation is defined by formula N=180/Asw+100×V_c, where A_sw in swinging amplitude, mm, V_c is casting rate, m/min, 100 is proportionality factor, cycle/min, 180 is empirical factor, mm.

EFFECT: higher quality and efficiency.
