Abstract
The invention discloses a rod production cooling control process and an apparatus thereof. A double-rule shear front cooling device, a double-rule shear front roller, a double-rule shear, a double-rule shear rear roller, and a double-rule shear rear cooling device are arranged behind a finishing mill group in sequence; the rod temperature is controlled twice through the double-rule shear front cooling device and the double-rule shear rear cooling device; the rod surface temperature is cooled twice through the front and rear water penetration cooling devices, so that the water penetration cooling control temperature is reduced to the maximum extent, the product performance is improved, and the production cost is further reduced.
Description
Technical field
The present invention relates to steel produce in process for cooling after finish rolling.Particularly relate to a kind of bar production Controlled cooling process and device thereof.
Background technology
At present, in bar production, for enhancing product performance, a large amount of employing wears water management process for cooling after rolling, this process characteristic is that finished surface temperature controls below 400 DEG C, but by the impact of existing equipment multi-length shear shear ability, wear the product after water and can only reduce Surface of Rod Bar temperature, and bar core temperature also maintains higher state of temperature, core heat makes Surface of Rod Bar temperature return to about 700 DEG C by thermal conductance mode to Surface of Rod Bar diffusion in transmitting procedure on roller-way, makes bar temp can not reach the low requirement of actual temperature.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention aims to provide a kind of bar production Controlled cooling process and device thereof.
The present invention is achieved by following technical solution:
A kind of bar production Controlled cooling process and device thereof, sequentially arrange after mm finishing mill unit: front cooling device after cooling device, multi-length shear front roller-way, multi-length shear, roller bed behind double length shear, multiple length before multi-length shear, is controlled by cooling device twice pair of bar temp front after cooling device before multi-length shear and multiple length.
Be provided with four in cooling device before described multi-length shear and wear water-cooling apparatus.
Be provided with three in cooling device before after described multiple length and wear water-cooling apparatus.
Before described multi-length shear, cooling device is 18 meters with the distance of doubly to cut chi, and before after multiple length, cooling device is 6 meters with the distance of doubly cutting chi.
The invention has the beneficial effects as follows:
Compared with prior art, a kind of bar production Controlled cooling process provided by the invention and device thereof, by doubly cutting Water cooling device before and after chi, twice cooling is carried out to Surface of Rod Bar temperature, Water cooling control temperature can be reduced to greatest extent, to enhance product performance, thus be more conducive to reducing production cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described further, but described in required protection domain is not limited to;
As shown in the figure, a kind of bar production Controlled cooling process provided by the invention and device thereof, sequentially arrange after mm finishing mill unit: front cooling device 5 after cooling device 1, multi-length shear front roller-way 2, multi-length shear 3, roller bed behind double length shear 4, multiple length before multi-length shear, is controlled by cooling device 5 twice pair of bar temp front after cooling device before multi-length shear 1 and multiple length.By doubly cutting Water cooling device before and after chi, twice cooling being carried out to Surface of Rod Bar temperature, Water cooling control temperature can be reduced to greatest extent
Be provided with four before described multi-length shear in cooling device 1 and wear water-cooling apparatus 6.
Be provided with three in cooling device 5 before after described multiple length and wear water-cooling apparatus 6.
Before described multi-length shear, cooling device 1 is 18 meters with the distance of doubly cutting chi, and before after multiple length, cooling device 5 is 6 meters with the distance of doubly cutting chi.
Operation principle: rod product is after last rolling of finish rolling, before entering multi-length shear immediately at high operating temperatures, cooling device 1 cools, cooled Surface of Rod Bar temperature reaches design minimum requirements temperature, and bar core temperature also maintains higher state of temperature, in multi-length shear front roller-way 2 running, core heat is spread to Surface of Rod Bar by thermal conductance mode, and the surface temperature when bar arrives multi-length shear 3 place can reach about 700 DEG C, is conducive to multi-length shear and shears.After multi-length shear is sheared, bar, in the process through roller bed behind double length shear 4, proceeds internal-external heat exchange, and after arrival multi-length shear during cooling device 5 entrance, Surface of Rod Bar temperature can reach about 750 DEG C.After last bar enters multi-length shear, cooling device 5 cools, and through the cooled bar product of this cooling controller, sends into cold bed carry out nature cooling by rollgang thereafter.
