Description
Technical Field
The utility model relates to a steel rolling technical field specifically is a be used for wire rod hot rolling to send out silk water smoke and dispel cold system.
Background
The controlled cooling technique after the wire laying head, also known as on-line heat treatment, is a key process directly related to the mechanical properties and uniformity of the final product. The added value of the product can be increased by adopting the post-rolling control cooling technology, and meanwhile, the production energy conservation is realized. The method has good effects of improving the social and economic benefits of the wire, promoting the production development of metal products and developing a new field of wire use.
The hard wire steel is in an austenite state in the rolling process after being heated, the austenite is decomposed and transformed in the controlled cooling process after being rolled, and different metallographic structures can be obtained at different cooling speeds. In order to obtain the sorbite structure, the traditional process adopts lead bath quenching, which has high labor intensity, high production cost and environmental pollution. In modern high-speed wire production, a stelmor control cooling process is adopted, and austenite can be converted within a certain specific temperature range by controlling the cooling speed of a rolled piece so as to obtain a metallographic structure meeting the performance requirements of products. The transformation of the hard wire steel is carried out on an air cooling roller way, so that the important point in controlling the cooling process is to determine the air cooling process parameters, the sorbite structure has excellent drawing performance, the lead bath quenching before drawing can be replaced, the wire is rapidly cooled after spinning, and then the sorbite can be obtained through isothermal cooling in the sorbite area. At present, a roller type air cooling transportation line is used after wire rods are rolled on site for spinning, and the cooling of cooling by an axial flow fan is realized. Therefore, how to overcome the above-mentioned defects becomes a problem to be solved urgently by this company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to overcome the defects, the utility model discloses a be used for wire rod hot rolling to send out silk water smoke and dispel cold system.
The utility model provides a be used for wire rod hot rolling to send out silk water smoke and disperse cold system, include pump, governing valve and the flowmeter that connects gradually through the pipeline, be equipped with the manometer on the pipeline, pipeline export is parallelly connected with a plurality of ball valves, the ball valve is connected with the shower through the high-pressure line, be equipped with a plurality of nozzles on the shower, the shower is installed in the air outlet of fan.
The pressure meter and the flowmeter are used for controlling the pressure and the flow of the spray pipe; the cooling water is pumped out under the action of the pump and enters the spray pipe, and when the fan runs quickly, the cooling water is directly blown off to the wire rod which is spun out by the rolling line through the nozzle by the wind power of the fan to carry out quick cooling; the utility model discloses not only convenient to use can effectually carry out rapid cooling to the laying wire rod fast moreover.
Furthermore, still be equipped with on the pipeline and be located the governing valve is imported and exported the first butterfly valve at both ends, and with the parallelly connected second butterfly valve of first butterfly valve. When the governing valve breaks down, close first butterfly valve, open the second butterfly valve to under the circumstances of guaranteeing system normal operating, be convenient for governing valve maintenance or change.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention, wherein there are two fans;
fig. 2 is a schematic structural diagram of the present invention, wherein there are three fans;

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The first embodiment is as follows:
as shown in fig. 1, the utility model relates to a be used for wire rod hot rolling to spout water smoke and disperse cold system, include pump 1, governing valve 2 and the flowmeter 3 that connects gradually through the pipeline, be equipped with manometer 9 on the pipeline, pipeline export parallel has two ball valves 4, and ball valve 4 is connected with shower 7 through high-pressure pipe 5, is equipped with a plurality of nozzles 8 on shower 7, and shower 7 is installed in the air outlet of fan 6.
And a first butterfly valve 10 positioned at the inlet and the outlet of the regulating valve 2 and a second butterfly valve 11 connected with the first butterfly valve 10 in parallel are also arranged on the pipeline. When the regulating valve 2 is in failure, the first butterfly valve 10 is closed and the second butterfly valve 11 is opened, so that the regulating valve 2 can be conveniently repaired or replaced under the condition that the normal operation of the system is ensured.
The pressure gauge 9 and the flowmeter 3 are used for controlling the pressure and the flow of the spray pipe 7; the cooling water is pumped out under the action of the pump 1 and enters the spray pipe 7, and when the fan 6 runs rapidly, the cooling water is directly blown off to the wire rod which is spun out by the rolling line by the wind power of the fan 6 through the nozzle 8 for rapid cooling; the utility model discloses not only convenient to use can effectually carry out rapid cooling to the laying wire rod fast moreover.
Example two: compared with the first embodiment, the differences are as follows: as shown in fig. 2, the pipeline outlet is connected in parallel with three ball valves 4.
