Abstract

The invention discloses a dual-swirl tangential outer mixed type water atomizing nozzle, and relates to the technical field of design and manufacture of water atomizing nozzles for continuous casting machines. A gas swirler is arranged at the lower part of a water inlet hole. A water swirler is arranged in the gas swirler. The working principle of the product is as follows: high-pressure gas and high-pressure water are filtered through a gas inlet and a water inlet respectively and then enter into a body; the high-pressure gas generates swirl when passing through the gas swirler; the high-pressure water generates swirl when passing through the water swirler; and the swirl gas and swirl water strike each other directly so that the cooled water can be sufficiently atomized for cooling a continuous casting billet. The dual-swirl tangential outer mixed type water atomizing nozzle has a simple structure and is reasonably designed; and due to the water swirler and the gas swirler, the atomizing effect of the cooled water is excellent, the water is uniformly sprayed on the surface of the continuous casting billet, and the uniformity of heat exchange between the spraying water and the surface of the casting billet is guaranteed. The quality of the continuous casting billet is improved, and the atomizing is uniform. Moreover, as a water channel is surrounded by a gas channel, a water quantity controller is cooled during the work, and scaling due to high temperature is avoided. The problems of the existing cooling nozzle are solved.

Description

Bispin stream tangential exterior mixing water atomizing nozzle
Technical field
The present invention relates to design and the manufacturing technology field of conticaster with water atomizing nozzle.
Background technology
At present in process of production, molten iron or steel scrap process are smelted and refining, cast the continuous casting billet of various end faces again through conticaster by converter.In the process of casting continuous casting billet, all to carry out cooling processing to the surface of continuous casting billet, be on the conticaster cooling section, to install the cooling water nozzle additional, aborning the continuous casting billet surface is sprayed cooling.And the quality of cooling effect directly influences the quality of steel billet.The cooling water nozzle that uses on the existing conticaster as water-atomizing nozzle gentle-atomizing nozzle.Along with the development of technology, increasingly high to the steel product quality requirement, and in the steel billet casting process; Cooling effect is very crucial, and existing nozzle is owing to structural reason, and it is not good to exist the cooling water atomizing effect; Inhomogeneous to the continuous casting billet surface spraying, thus the quality of product influenced.
Summary of the invention
To above-mentioned situation, the purpose of this invention is to provide the better cooling water nozzle of a kind of atomizing effect, to solve the problem that existing product exists, improve the quality of product.
The present invention addresses the above problem the technical scheme of being taked to be; In nozzle upper part of body one side one air admission hole is arranged, an annular groove is arranged on the neighboring of air admission hole, in annular groove, have sealing ring.Opposite side has an inlet opening on nozzle body top, and the neighboring of inlet opening also has sealing ring.In air admission hole, have the gas filtration net.In the inlet opening, have water sieve.One fabrication hole bolt is arranged on the left side of nozzle body.In fabrication hole bolt inboard one gas storage chamber is arranged.One gas flow control hole is arranged on the gas storage chamber front end.One gas cyclone device is arranged in the bottom of inlet opening.In the gas cyclone device, have water cyclone.On the top of water cyclone one reservoir is arranged.In the bottom of water cyclone one collect cavity is arranged.One gas flow control hole is arranged in the bottom of gas cyclone device.In the bottom of gas cyclone device one shower nozzle is arranged.In shower nozzle, have the gas-vapor mix chamber.One hold-down bolt is arranged between shower nozzle and nozzle body.One gas cyclone chamber is arranged between gas cyclone device and nozzle body.
Operation principle of the present invention is: gases at high pressure and water under high pressure get in the body through air inlet and water inlet respectively after filtering, and gas enters into the gas cyclone chamber through gas storage chamber.Cooling water gets into the gas-vapor mix chamber through water cyclone after getting into reservoir.Gases at high pressure are joined with water after also getting into the gas-vapor mix chamber.At this moment, gases at high pressure produce eddy flow through the gas cyclone device time, and water under high pressure produces eddy flow through water cyclone the time; The gas of eddy flow and the mutual frontal impact of the water of eddy flow; Cooling water can fully be atomized, from the spray orifice ejection of shower nozzle front end, continuous casting billet is carried out cooling processing then.The present invention is simple in structure; Reasonable in design; Owing to have water cyclone, gas cyclone device and gas storage chamber, gas-vapor mix chamber, gas cyclone chamber etc., make that the atomizing effect of cooling water is splendid, spray surface equably at continuous casting billet; Greatly improve cooling effect, guaranteed the uniformity of heat exchange between shower water and casting billet surface.Improved the quality of continuous casting billet.Cold steel grade a little less than being particularly useful for.In addition, because the aqueous vapor import has screen pack, avoided jet to be stopped up by foreign material.Because atomizing evenly.Be that gas passage has surrounded aquaporin in addition, make water quantity controller obtain cooling at work, can Yin Gaowen and fouling.Solved the problem that existing cooling nozzle exists.
