Description

one

The invention relates to metallurgy and mechanical engineering and can be used to cool steel during heat treatment or to produce it in rolling mills.

The aim of the invention is to increase the efficiency and uniformity of cooling.

Figure 1 shows the device, a general view; figure 2 - node I in figure 1; on fig.Z - section aa in figure 1.

The device contains a collector 1 with siphon tubes 2. At the exit of each siphon tube, evenly over the area of its opening are installed inserts 3 with nozzles 4. The insert on the side opposite to the exit of the siphon tube is plugged with a washer 5i The inserts are installed evenly over the cross section of the opening of the siphon tube, the total the opening area of the inserts is 0.2-0.8 the opening area of the siphon tube.

The device works as follows.

Water is supplied to the collector 1 and air to the manifold 4. After the collector 1 is filled, water enters the siphon tubes 2. The siphon tube walls and air jets emerging from the inserts: 3 form a continuous flow of water, according to the flow. which is evenly distributed12571012

divided hollow cylinders. Air is supplied to the inside of each cylinder through nozzles 4. In the zone of contact of the flow of water supplied by the siphon tube with a strip, empty cavities are formed according to the number of inserts 3, which have no connection with the environment and with each other. A fine mixture of steam, water and air is formed in these cavities, which is evenly distributed over the cooled surface. This increases the intensity and uniformity of cooling.
