The invention relates to metallurgy of ferrous metals. A method for mixing of steel in ladle comprises the bottom blowing of steel by gas or gas-powder mix through provided at least two bottom blowing devices, which are located on diametrically opposite sides of ladle, at that top blowing through top submerged blowing devices simultaneously with bottom blowing is carried out by combination and by turn not opposite bottom and top blowing devices. Technical result: providing of supply of gas or gas-powder mix with seizing as much large volume of metal for carrying out of optimum mixing of steel in ladle, decreasing of “stagnant zones”, averaging of metal on chemical compound and temperature, increasing of steel quality.
