A method of continuous casting of a steel employs a mold power having a viscosity of 0.5-1.5 poise at 1,300.degree. C. and a solidification temperature of 1,190-1,270.degree. C., in which the mass ratio of CaO to SiO.sub.2 is 1.2-1.9, and casting is carried out under the following conditions: casting speed is 2.5-10 m/minute; mold oscillation stroke is 4-15 mm; and specific cooling intensity in secondary cooling of a slab is 1.0-5.0 liter/kg-steel.

Метод непрерывной отливки стали использует силу прессформы имея выкостность 0.5-1.5 пуаз на 1,300.degree. C и температура затвердевания 1,190-1,270.degree. C, в котором массовый коэффициент caO к SiO.sub.2 1.2-1.9, и отливка снесены вне под following условия: скорость отливки 2.5-10 m/minute; ход колебания прессформы 4-15 миллиметров; и специфически охлаждая интенсивность в вторичный охлаждать сляба 1.0-5.0 liter/kg-steel.
