Abstract
The forced cooling process and apparatus for hot rolled thick wall seamless steel pipe belongs to the field of hot rolled steel rolled steel pipe cooling technology. Hot rolled thick wall seamless steel pipe is first cooled in a cooling bed to the temperature below metal phase change temperature and then forced cooling in a forced cooling station with medium pressure water sprayer. If necessary, the hot rolled thick wall seamless steel pipe will be further forced cooled in a cooling tunnel with medium pressure water sprayer. The fast cooling process of the present invention has the advantages of high production efficiency, reduced cooling bed length and saving in investment.
Description
Technical field:
The invention belongs to hot finished steel pipe cooling technology field, be specifically related to a kind of hot rolling posted sides seamless steel pipe cooling process and device.
Background technology:
At present, all on cold bed, undertaken for the cooling of the seamless steel pipe after the hot rolling both at home and abroad by air cooling, this type of cooling is feasible for general steel pipe, but for some thick walled steel tubes, especially extra strong pipe adopt this mode can be oversize because of cool time, cold bed length do not reach the cooling requirement inadequately.
The object of the invention provides a kind of new technical scheme, can overcome the shortcoming that prior art exists effectively.
The present invention is achieved in that it is by air cooling or forced air-cooling on cold bed with the thick-walled seamless steel pipes after the hot rolling, steel pipe is cooled to below the metal phase change temperature, the pressure cooling stations of setting-out spray equipment was forced cooling during handover entered and is equipped with again, at this moment, if also do not reach the chilling temperature requirement, can again steel pipe be delivered into the cooling tunnel that middle setting-out spray equipment is installed and force cooling.
Advantage of the present invention and good effect are that heavy wall or special heavy wall hot rolled seamless steel tube are cooled off fast, both can save cool time, enhance productivity, and also can save cold bed length, reduce investment outlay.
Description of drawings:
Fig. 1 is the pressure cooling stations structure diagram of setting-out spray equipment in installing
Fig. 2 is the cooling tunnel structure diagram of setting-out spray equipment in being equipped with
Fig. 3 is a B-B cutaway view among Fig. 2
Among the figure: 1---support, 2---pipeline, 3---shower nozzle, 4---steel pipe, 5---cover body, 6---roller-way, 7---ring pipe, 8---shower nozzle, 9---inlet channel, 10---frame, L---steel pipe 4 vertical throughput directions,
The specific embodiment:
As shown in Figure 1, the pressure cooling stations structure diagram of setting-out spray equipment in the installation.The pipeline 2 that many radicles are equipped with a plurality of shower nozzles 3 is installed on support 1, support 1 is supported on the upper position that steel pipe 4 laterally moves with pipeline 2 and shower nozzle 3, steel pipe 4 in doing the process that rotation type laterally moves forward, from shower nozzle 3 sprays come out setting-out can force cooling pipe 4.
Shown in Fig. 2,3, the cooling tunnel structure diagram of setting-out spray equipment in being equipped with, be equipped with on ring pipe 7 circumferential wall that are connected with inlet channel 9 a plurality of can be to the shower nozzle 8 of setting-out in the central part spray, ring pipe 7 is installed on the cover body 5, cover body 5 is installed on the support 10, steel pipe 4 moves forward under rollgang drives, and by ring pipe 7 central parts, from shower nozzle 8 spray out setting-out can force cooling pipe 4.
