(54) SOCK OF GOLD

I

I The conversion of ognosigs to the metallurgical industry can be used mainly in blast furnaces.

Known socks gutters to drain the melt, for example, cast iron. Chutun from the blast furnace enters the iron scoop along the chute. The chute ends when & with a toe which is intended to form a stream of cast iron going into the ladle. Sliya oh sock Bbiciynaei; over the edge of the working pgatsadki in the direction of the cast-iron ladle. It is attached to the gutter with detachable joints, for example with bolts L--}

Such flush socks are used to fill conventional type cast iron buckets with large neck sizes for loading and pouring iron. In the “mixed-type mixing vessels, the throat is considerably smaller. When the mixing bucket is filled, liquid iron splashes fall on its body and form an accumulation, i.e. outgrowth of frozen pig iron. A jet of liquid iron, pop on the body of the mixing bucket, can burn it. Therefore, a stream of cast iron is desirable to give a direction from the drain toe vertically down.

The closest to the invention to the technical essence is the SIBI sock containing a lined container with a vertical channel. P {this is the stream of cast iron from the chute. It enters directly into the channel through which the iron flows into the ladle 123.

Claims (2)

The disadvantage of this design of the drain sock is that the cast iron stream, hitting the footer of the wall of the vertical channel opposite to the trough, can break it. This removes the drain sock; damage to the mixing bucket by jet iron is also possible. Thus, the use of well-known drain socks worsens the operating conditions of the mixing ladles, increases the number of their repairs, contributes to the formation of wall accretions and increases the loss of pig iron with scrap. The durability of drain socks with a vertical channel is not palpable. The purpose of the invention is to reduce the amount of scrap and increase the durability of the nose. The goal is achieved by the fact that in the toe of the gutter containing a lined container with a vertical channel, the axis of the vertical channel is displaced relative to the axis of the gutter within 0, 6, 6 of the diameter of the vertical channel. FIG. 1 shows a sock; a view of cxyxyj in FIG. 2 is a section A-A in FIG. Ij in FIG. S - section bb in fig. 2. Drain sock (Fig. 1, 2, 3) is connected to chute I, Vertical channel 2 is made in the drain nose. around vertical channel 2. At the same time, the stream of cast iron does not hit the wall of the drain toe and cast iron flows down the vertical channel into the ladle. The ecohomic effect is determined by the lower costs of repairing mixers and the reduction of waste from scrap with scrap. The economic effect when loading I 1, About million tons cast iron constitutes 10 thousand. Formula of the invention The sock of the gutter containing a lined container with a vertical channel, so as to reduce the amount of scrap during metal casting and increase the resistance of the toe to the axis of the gutter by 0 4-O, 6 diameters of the vertical channel.
