    • The invention relates to metallurgy, in particular to production of metal shot from a molten metal or alloy by casting. According to the claimed method for producing shot, melt fragments, as obtained by passing a melt through a die which passages consist of two successive sections, are cooled by a spilling flow of an air-droplet mixture and are placed into a cooling liquid. Another aspect of this invention is the device for producing shot from a molten metal or alloy for carrying out the claimed method. Yet another aspect of this invention is a device for cooling melt fragments of a molten metal or alloy, as produced by passing a melt through a die, which comprises one or more nozzles for supplying a sprayed cooling air-droplet mixture as a spilling flow to a space under the crucible. Still another aspect of this invention is a die for producing shot from a molten metal or alloy, which is arranged in the crucible bottom and which passages consist of two sections performing the functions of a dosing passage and an isothermal chamber. The technical effect of the claimed invention is production of shot with a high degree of sphericity and fractional composition.

    • The invention relates to ferrous metallurgy, in particular, to production of steel slabs by continuous casting. In the claimed method for continuous casting of steel, superheated metal is fed from an intermediate ladle to a mold having a rectangular cross-section by means of a submersible nozzle, which has a sprue channel in its upper part adjacent to the intermediate ladle; the sprue channel branches in the lower part of the nozzle to at least two closed- bottom outlet channels. The closed-bottom outlet channels are located within the nozzle limited by a skirt that stretches toward the narrow edges of the mold and joins with the nozzle above the level where the closed-bottom outlet channels branch, and by the lower edge of the skirt located below the level of the bottom of the closed-bottom outlet channels. Each closed-bottom outlet channel has two diametrically positioned and horizontally directed outlets, wherein the axes of the outlets form an angle that is not 90º with the wide edge of the mold in the horizontal plane. Another object of the invention is a submersible nozzle for implementation of said steel casting method. The claimed method for continuous casting of steel and submersible nozzle used therein result in an increased rate of casting, providing more uniform volumetric metal temperature and reduced wearing of the submersible nozzle, thus increasing the efficiency of slab continuous casting devices.
    • 本发明涉及黑色冶金,特别涉及通过连续铸造生产钢板。 在所要求保护的钢的连续铸造方法中,过热金属通过潜水喷嘴从中间浇包供给到具有矩形横截面的模具中,该潜水喷嘴在其上部邻近中间浇包处具有浇口通道; 浇口通道在喷嘴的下部分支到至少两个封闭底部出口通道。 封闭底部的出口通道位于喷嘴限定的裙部内,该裙部朝着模具的窄边缘延伸,并且与喷嘴连接,其中封闭底部出口通道分支的水平面上方,并且裙部的下边缘位于 低于底部底部出口通道的水平面。 每个封闭底部出口通道具有两个直径定位和水平定向的出口,其中出口的轴线在水平面内与模具的宽边缘形成不是90°的角度。 本发明的另一个目的是一种用于实施所述铸钢方法的潜水喷嘴。 用于其中的钢和潜水喷嘴的连续铸造的所要求的方法导致铸造速率增加,提供更均匀的体积金属温度和减少潜水喷嘴的磨损,从而提高板坯连铸设备的效率。
