Description
Technical field
The invention belongs to hot rolled seamless steel tube production technical fields, control and cool down more particularly to a kind of hot rolled seamless steel tube
With annular jet cooling device.
Background technique
For a long time, hot rolled seamless steel tube is due to the particularity of its production technology and the complexity of ring section, with hot rolling
Plate, profile, Bar Wire Product are compared, and during Rolling Production, lack Controlled Rolling And Controlled Cooling means, and then cannot achieve effective
Structure property regulation.Its mechanical property is promoted in order to improve the microstructure of hot rolled seamless steel tube, relies only on addition at present
Alloying element or subsequent heat-treated offline process, cause production cost significantly improve and the reduction of production efficiency.If energy
On-line Control after enough realizing tubing hot rolling is cooling, then the structure property regulation of hot rolled seamless steel tube can be achieved, and can obviously drop
The manufacturing cost of low hot rolled seamless steel tube, while also production technology means are provided for the tube product of higher quality.Therefore, right
It is higher and higher in the attention degree of the On-line Control cooling technology of hot rolled seamless steel tube, and there is an urgent need to develop go out to be suitable for hot rolling
The cooling equipment of seamless steel pipe On-line Control cooling technique.
Currently, controlling the development of cooling equipment rapid deployment for hot rolled seamless steel tube, and have already appeared
The cooling equipment schemes of a variety of correlations based on different principle and form, still, these existing technical solutions are more or less still
Come with some shortcomings place, specific as follows:
1. the Chinese patent application of Publication No. CN103264054A, it discloses a kind of steel pipe homogeneous cooling apparatus,
In the patent formula, the adjustable nozzle on cooling water tank the water spray sprayed water to outer wall of steel pipe has been arranged to
Ring, the center line of water ring and the traffic direction of steel pipe are in 5 °~175 ° of angle, and pass through cooling water water blocking mechanism and cooling
The cooling to steel pipe is realized in the cooperation of water water spraying mechanism, and cooling water water spraying mechanism maintains a normally open state.
But in above-mentioned patent formula, the adjustable means of cooling water water spraying mechanism are not referred to clearly, and are directed to
When the steel pipe of different-thickness specification is cooled down, in order to meet the demand for control of different final cooling temperatures, water ring, which opens quantity, is
Important regulating measure, but the cooling water water spraying mechanism in patent formula is normally open, has lacked regulating measure, has also resulted in
The waste of water resource.
2. the Chinese patent application of Publication No. CN101570813A, it discloses a kind of directly quenching seamless steel pipes dresses
It sets, in the patent formula, outer surface cooling device is made of annular cooler, and inner surface cooling device is rod-shaped, and position
In the top of variable-angle roller-way, and it is inserted among the annular cooler of outer surface.
But although when by the inside of steel pipe market to annular cooler and the outside of inner surface cooler, it is possible to implement
Quenching technical, but the quenching unit is unable to satisfy the cooling demand of control, also just can not realize end according to structure property needs
The accurate control of cold temperature.
3. the Chinese patent application of Publication No. CN201455003U, it discloses a kind of seamless pipe controlled rolling and controlled coolings realized
The spray tube for being equipped with several nozzles is uniformly arranged around water ring axis in the patent formula and constitutes cage knot by device
Structure, and spray nozzle axis and vertical line are in 5 °~20 ° of angle, to implement to cool down to steel pipe circumferencial direction.
But the geometric dimension of the device needs to match with the seamless steel pipe of certain size, causes the device that can fit
Steel pipe specification is restricted, and since arrangement of nozzles form is more single, therefore, it is difficult to Effective Regulation steel pipe circumferencial directions
Cooling uniformity.
4. the Chinese patent application of Publication No. CN86202942U, it discloses a kind of steel pipe continuous controlled cooling equipment,
In the patent formula, steel pipe is cooled down using the cyclone water formed in cooler.
But using the souring of rotary water current come cooling pipe, due to the poor controllability of cyclone water in cooling procedure,
It is difficult to accurately control final cooling temperature.
