Abstract
The utility model discloses an on-line cooling fan-shaped nozzle device for a medium-thickness plate after rolling, and the device comprises a box-shaped body and nozzles. The device is characterized in that two rows of stepped holes at each side of an ejecting plate of the box-shaped body are inclined stepped holes which incline outwards; the gradient of the outer inclined stepped holes of one side is greater than the gradient of the adjacent inner inclined stepped holes; the central three rows of stepped holes are also vertical stepped holes; after the nozzles are screwed into inner threaded holes of the stepped holes, two rows of nozzles at two sides are arranged in an inclined manner. The device is advantageous in that the nozzles, which are symmetrically arranged at the two sides at different ejecting angles and used for ejecting, can scour the surface of a high-temperature steel plate back and forth at certain angle, thereby enlarging the ejecting area; jet-flow impact heat transfer happens near an impact zone; a jet flow can plays a water-sealing role in a jetting water flow of back and front collecting tubes, thereby preventing a water flow on the surface of a rolled piece from flowing without order.
Description
Technical field
The utility model relates to cut deal and rolls rear on-line cooling technology, particularly a kind of cut deal and roll rear on-line cooling " fan-shaped " spray nozzle device.
Background technology
At present, for hot rolled steel plate production line, roll the very large cooldown rate of rear common needs and obtain good tissue and performance, particularly recent domestic grow up for the cooling new technology of control panel band, there is direct quenching, accelerate cooling, the ultrafast multiple power such as cold, can the cooling process control of high accuracy and the finely regulating of steel tissue, performance, for realizing the multiple strengthening of refined crystalline strengthening, precipitation strength, phase transformation strengthening and the lifting of material property provides means.
Milling train is laid with the lower header upwards spraying between adjacent two transfer rollers of rear conveyer belt, is laid with up corresponding upper water box and sprays downwards.Water tank is box-like body, the wide two roller spacing that are less than, and it is long that length is less than transfer roller.The water inlet of box-like body is communicated with water source tube by valve.The roof box of lower header, the lower shoe of upper water box are as jet plate, jet plate is slab, on jet plate, be drilled with seven row stepped holes of horizontal laying, interior stepped hole is screwed hole, and stepped hole is vertical with jet plate face, and two adjacent row stepped holes misplace each other, a upright nozzle is installed in each screwed hole, nozzle cylindrical is step column, and the interior step post cylindrical of nozzle is external screw thread, and inner circle is stepped hole; The external screw thread of nozzle screws up in the screwed hole of the interior stepped hole of jet plate.Can certainly lay 5-10 row screwed hole by concrete condition design.
The existing quick cooling highly dense nozzle of arranging with same spray angle, because small nozzle in its cooling water high pressure, high flow rate, the high water yield and nozzle unit are is arranged highdensity characteristic, it sprays cooling current and there will be the problems such as phase mutual interference, impeded drainage, cause cooling effectiveness low, the shortcomings such as cooling uniformity is poor, are difficult to reach cooling to rolled piece high speed and guarantee the good object of rolled piece plate shape.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provides a kind of cut deal to roll rear on-line cooling " fan-shaped " spray nozzle device.
The utility model scheme is: comprise box-like body, nozzle, it is characterized in that: on the jet plate of box-like body, two row stepped holes of every avris are respectively the oblique stepped hole of outside deflection, the oblique stepped hole gradient in one-sided outside is larger than adjacent inner side step hole gradient, middle three row stepped holes are still vertical stepped hole, nozzle is screwed into after the internal thread hole of stepped hole, and avris two row nozzles are tilting shape.
The utility model has the advantage of: the nozzle jet that both sides are arranged symmetrically with different jet angles, can impact forwards, backwards at a certain angle high-temperature steel plate surface, strengthen jet face, near shock zone, there is jet impingement heat transfer, this injection stream can also play the water seal effect of front and back collector institute water jet simultaneously, prevents that rolled piece surface current disordered flow is moving.

the specific embodiment
The utility model structure comprises box-like body 1, nozzle 2, it is characterized in that: on the jet plate of box-like body 1, two row stepped holes of every avris are respectively the oblique stepped hole of outside deflection, the oblique stepped hole gradient in one-sided outside is larger than adjacent inner side step hole gradient, middle three row stepped holes are still vertical stepped hole, nozzle 2 is screwed into after the internal thread hole of stepped hole, and avris two row nozzles 2 are tilting shape.
Arrange that vertical nozzle 2 is more conducive to the discharge of cooling water compared with the nozzle 2 of arranging with same spray angle of arranging combining with the nozzle 2 of certain rake angle layout, prevents that cooling water is listed as between row and forms " waterwall " phenomenon fluctuated at nozzle 2 simultaneously.Therefore cooling uniformity and cooling effectiveness increase substantially.
