Abstract

PURPOSE:To spray efficiently and continuously air and water for cooling a billet with a continuous casting machine by introducing water in the form of a thin film from a narrow part between the outside circumferential surface of an orifice for air and the inside circumferential surface of an air piping into a part for mixing with air. CONSTITUTION:An orifice 4 for air provided in an air piping 1 is formed to a large diameter to form a narrow part 4b between the outside circumferential surface thereof and the piping 1 and a hole 4a is provided in the central part of the orifice 4 in an air-water spray nozzle for cooling a billet with a continuous casting machine which mixes the air and water introduced therein through the piping 1 and a water piping 2, respectively, and sprays the air and water from a nozzle tip 5. The water introduced through the orifice 3 into said nozzle from the piping 2 is passed through said part 4b and is introduced in the form of a thin film into a mixing part A, where the water is mixed with the pressurized air introduced from the hole 4a and is ejected in the form of mist-like water drops from the nozzle of the tip 5.

More precisely, by mixing pressurized air with water and converting the W dynamic energy of the air into water interlocking energy and atomization energy, the jet from the nozzle is created. This invention relates to an air-water spray nozzle for using the mist-like water droplets generated during the cooling process to slowly cool the slab.

ネルギーを要し、このため霧化腸性はよくない。The water and air that are accelerated while passing through the orifices 2 and 4 are mixed and agitated in the mixing section A, and are discharged from the nozzle tip 5 in a dew shape. In this mixing section A, water is partially atomized by the shearing force of the air determined by the relative velocity difference between water and air. However, in the conventional structure, since the water flow after passing through the orifice 2 is columnar, a large amount of energy is required to purify the water Qla, and therefore the atomization properties are not good.

To summarize its configuration, in order to introduce the flow of water into the mixing section in the form of a thin film as much as possible, the film is formed from an annular constriction formed between the outer periphery of the air orifice and the air and piping, centering on the air orifice. Create a shaped water flow,
This is then introduced into the mixing section.

Now, water entering from the water pipe 2 passes through the water orifice 6, and then passes through the narrow part on the outside of the air orifice 4 and is introduced into the mixing section A.

The mixture is introduced into the mixing section A through a hole 4a provided in the center.

An annular narrowed portion 4b is formed between the inner diameter of the tube and the inner diameter of the tube. While passing through this narrowed part 4b, the water becomes a thin film-like flow, and in the mixing part A, it is easily separated by the flow of air from the center and becomes a small drop of water.

し、約り０％少い空気量で霧化が可能なことが判る。Figure 3 is a graph showing the relationship between the amount of water flowing into the spray nozzle and the amount of air required for atomization. Case 1-j It can be seen that atomization is possible with approximately 0% less air amount than the conventional type.

This requires less energy, and the atomization properties can be further improved.
