The utility model is related to hot continuous rolling technical field more particularly to a kind of hot continuous rolling production lines, including:Roughing mills, roughing De-scaling box, water shutoff equipment;The roughing De-scaling box is located at the entrance of the roughing mills;In the exit of the roughing De-scaling box, the water shutoff equipment is set;In the inlet of the roughing mills, the water shutoff equipment is set.Water shutoff equipment is arranged by the inlet in the exit of roughing De-scaling box and roughing mills in the utility model, can be blocked to de-scaling water and cooling water of working roll, de-scaling water and cooling water of working roll is avoided to cause non-uniform cooling to slab.

Description

A kind of hot continuous rolling production line
Technical field
The utility model is related to hot continuous rolling technical field more particularly to a kind of hot continuous rolling production lines.
Background technology
On hot continuous rolling production line, pony roughing mill inlet and outlet and mm finishing mill unit entrance are provided with device for descaling by high-pressure, Steel slab surface is secondary and iron scale three times for removing for device for descaling by high-pressure, to ensure that strip surface quality control is normal. However, since de-scaling water pressure is higher, usually in 160bar or more, therefore, dephosphorization water can cause after hitting to steel slab surface De-scaling water spluttering, while negative direction of a large amount of residual water along steel slab surface along rolling direction outflows, to slab tail portion, head with And edge causes bad cooling, it is even in turn result in slab inhomogeneous cooling, influence of rolled stability and quality control stability.
Utility model content
In view of the above problems, it is proposed that the utility model overcoming the above problem in order to provide one kind or solves at least partly The certainly hot continuous rolling production line of the above problem.
The utility model embodiment provides a kind of hot continuous rolling production line, including:Roughing mills, roughing De-scaling box, water shutoff are set It is standby;
The roughing De-scaling box is located at the entrance of the roughing mills;
In the exit of the roughing De-scaling box, the water shutoff equipment is set;
In the inlet of the roughing mills, the water shutoff equipment is set.
Preferably, the water shutoff equipment includes water blocking chain, air-blowing pipe and regurgitates collector group.
Preferably, the water blocking chain suspension is in the outlet of the roughing De-scaling box;
The air-blowing pipe is arranged in the exit of the roughing De-scaling box, and, the outlet of the air-blowing pipe is towards described thick Roll the outlet of De-scaling box;
The collector group of regurgitating is arranged in the inlet of the roughing mills, and, the nozzle direction for regurgitating collector group The entrance of the roughing mills.
Preferably, 500~700mm of roller-way upper surface of roughing mills described in the nozzle distance for regurgitating collector group.
Preferably, the injection direction for regurgitating collector group and the angle of vertical direction are 40~50 °.
Preferably, the injection direction for regurgitating collector group and the angle of vertical direction are 45 °.
Preferably, the purging direction for regurgitating collector group is identical as the slab rolling direction of the roughing mills.
One or more of the utility model embodiment technical solution, has at least the following technical effects or advantages:
Water shutoff equipment is arranged by the inlet in the exit of roughing De-scaling box and roughing mills in the utility model, can De-scaling water and cooling water of working roll are blocked, avoid de-scaling water and cooling water of working roll from causing slab non-uniform cold But.
Description of the drawings
By reading the detailed description of hereafter preferred embodiment, various other advantages and benefit are common for this field Technical staff will become clear.Attached drawing only for the purpose of illustrating preferred embodiments, and is not considered as to this practicality Novel limitation.And throughout the drawings, identical component is indicated with identical reference pattern.In the accompanying drawings:
Fig. 1 shows the First partial structural schematic diagram of the hot continuous rolling production line in the utility model embodiment;
Fig. 2 shows the second partial structural diagrams of the hot continuous rolling production line in the utility model embodiment.
Wherein, 1 is roughing De-scaling box, and 2 be water blocking chain, and 3 be air-blowing pipe, and 4 is regurgitate collector group, and 5 be roughing mills.
Specific implementation mode
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure Completely it is communicated to those skilled in the art.
The utility model embodiment provides a kind of hot continuous rolling production line, as depicted in figs. 1 and 2, the hot continuous rolling production line Including:Roughing mills 5, roughing De-scaling box 1, water shutoff equipment.Roughing De-scaling box 1 is located at the entrance of roughing mills 5, in roughing de-scaling Water shutoff equipment is arranged in the exit of case 1, and water shutoff equipment is arranged in the inlet of roughing mills 5.Wherein, it is located at roughing De-scaling box 1 Exit and the water shutoff equipment of inlet of roughing mills 5 de-scaling water and cooling water of working roll can be blocked, avoid De-scaling water and cooling water of working roll cause non-uniform cooling to slab.
Specifically, water shutoff equipment includes water blocking chain 2, air-blowing pipe 3 and regurgitates collector group 4.Water blocking chain 2 is suspended on slightly The outlet of De-scaling box 1 is rolled, air-blowing pipe 3 is fixed on the exit of roughing De-scaling box 1, and, the outlet of air-blowing pipe 3 is towards roughing de-scaling The outlet of case 1, air-blowing pipe 3 use high pressure air-blowing, regurgitate the inlet that collector group 4 is fixed on roughing mills 5, and, regurgitate collector Entrance of the nozzle of group 4 towards roughing mills 5.
In preferred embodiments, regurgitate the roller-way upper surfaces 500 of the nozzle distance roughing mills 5 of collector group 4~ 700mm.The injection direction of collector group 4 is regurgitated according to the adjustment of onsite application effect and purging direction, guarantee regurgitate water in slab table The angle of the purging effect in face, the injection direction and vertical direction of regurgitating collector group 4 is 40~50 °, it is preferred that regurgitates collector group 4 injection direction and the angle of vertical direction are 45 °, in addition, regurgitating the slab in the purging direction and roughing mills 5 of collector group 4 Rolling direction is identical.
