Abstract
The utility model relates to a device for preventing intermediate billet head raising, including condenser tube and shower nozzle, condenser tube installs between adjacent postpone roll table, and the last range of condenser tube is provided with the shower nozzle, and the apopore of shower nozzle is up. The utility model discloses simple structure, convenient operation, effectual lower surface to the steel slab cools off, prevents that the steel slab from sticking up the head to production accident rate has been reduced.
Description
Technical field
The utility model relates to a kind of protector, particularly relates to a kind of device that prevents the intermediate blank nose.
Background technology
In the hot rolling production technology, when rolling, steel billet lower surface heating temperature is high in finishing mill for high-strength steel; Caused the phenomenon of steel billet nose in finishing mill; Hot rolling production there is very big danger, causes the generation of production accident easily, thereby influenced the normal production order.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of simple in structure, easy to use, the device that prevents the intermediate blank nose of good cooling results.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of device that prevents the intermediate blank nose comprises cooling water pipe and shower nozzle, and cooling water pipe is installed between the adjacent delay roller-way, is disposed with shower nozzle on the cooling water pipe, and the apopore of shower nozzle up.
Shower nozzle interleaved formula structural design on described adjacent two cooling water pipes, promptly the space between adjacent two shower nozzles is corresponding on the position of one of them cooling water pipe upper nozzle and another cooling water pipe.
Distance on the same cooling water pipe between the adjacent shower nozzle is 150～300mm.
Distance on the same cooling water pipe between the adjacent shower nozzle is 200mm.
The diameter of described shower nozzle apopore is 2.5～4mm.
The diameter of described shower nozzle apopore is 3mm.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is simple in structure, and is easy to use, through postponing between roller-way cooling water pipe to be installed, high strength steel slab lower surface cooled, and reached the purpose that reduces the steel billet upper and lower surfaces temperature difference, thereby avoided the generation of nose accident.
Description of drawings
Fig. 1 is the utility model mounting structure sketch map;
Fig. 2 is the nozzle structure sketch map.
The specific embodiment
A kind of device that prevents the intermediate blank nose like Fig. 1, shown in Figure 2, comprises cooling water pipe 1 and shower nozzle 2, and cooling water pipe 1 is installed between the adjacent delay roller-way 3, is disposed with shower nozzle 2 on the cooling water pipe 1, and the apopore 4 of shower nozzle 2 up.Shower nozzle 2 interleaved formula structural designs on two adjacent cooling water pipes 1, promptly the space between adjacent two shower nozzles 2 is corresponding on the position of one of them cooling water pipe 1 upper nozzle 2 and another cooling water pipe 1.Distance L on the same cooling water pipe 1 between the adjacent shower nozzle 2 is 150～300mm, and the diameter d of shower nozzle apopore 4 is 2.5～4mm.
Embodiment one
