Abstract
The utility model relates to a metallurgical nozzle head, comprising a nozzle head body. A water inlet is arranged at the bottom end of the nozzle head body, and a water spray outlet is arranged at the top of the nozzle head body; positioning steps are arranged at two sides of the nozzle head body; and the water inlet, the water spray outlet and the positioning steps are arranged as an integral structure. The metallurgical nozzle head has reasonable structure and simple manufacturing process and is formed by molding at one time and is firm and wear resistant; and the service life of the nozzle head is effectively prolonged.
Description
Technical field
The utility model has related to a kind of water injector, has particularly related to a kind of metallurgical nozzle head.
Background technology
At present, domestic each big steel mill hot rolling workshop adopts metallurgical nozzle head to the processing of scaling of the primary iron scale of rolled products and regenerating oxidation iron sheet in the dephosphorization process, and its nozzle head delivery port generally adopts the mechanical grinding processing mode to make.Mechanical grinding is made the outlet of nozzle water spray, need to adopt the grinding tool of the figure abrasive disc of being with certain angle or degree of geometrical, grind the zanjon of a band geometry at the nozzle head top, and zanjon traverses the nozzle head top, the nozzle that this mode is made has following several defective:
1, the manufacturing of nozzle delivery port shape be difficult for qualified.
2,, and certain degree of geometrical is arranged owing to the grinding manufacturing, the attenuation of nozzle delivery port outer rim, high pressure resistant water does not wash away, nozzle head shortening in service life.
3, because the grinding zanjon traverses the nozzle head top, make the attenuation of nozzle local wall thickness, intensity reduces, and cracking causes nozzle head shortening in service life easily.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides that a kind of reasonable in design, manufacture craft are simple, the metallurgical nozzle head of long service life.
In order to address the above problem, the utility model by the following technical solutions:
A kind of metallurgical nozzle head comprises the nozzle head body, and nozzle head body bottom is provided with water inlet, and the top is provided with the water spray outlet, and nozzle head body both sides are provided with positioning step, and water inlet, water spray outlet and positioning step adopt the integral structure design.
Described water spray outlet is the elliptical table cylinder, oval billiard table body, important actor body or the three-dimensional combining form of its its arbitrary ellipse; The cross section of the front edge of described water spray outlet is oval or circular; The cross section of the terminal edge of described water spray outlet is oval, circular or other arbitrary form polygon; The two sides of described positioning step are parallel to each other; Described nozzle head body adopts a compression moulding.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model adopts time processing to be shaped, and manufacture craft is simple, need not machined, thus alleviated labour intensity, improved the processing operating efficiency.
2, the delivery port of metallurgical nozzle head adopts a press forming, sound construction.Increase nozzle arrangements intensity and wear-resistant degree, effectively prolonged the service life of nozzle head, thereby improved the benefit of enterprise.
