Abstract

The utility model discloses a steel billet continuous casting secondary cooling zone full-covering cooler which includes cooling jets arranged in a secondary cooling zone and on the circumference of the same radius from the center of a steel billet, and is characterized in that the horizontal angle between the cooling jets is less than 90 degrees and more than 20 degrees. The preferred horizontal angle between the two cooling jets is 45 degrees. In the utility model, the horizontal angle is set to be 45 degrees, and the best spraying and cooling effect can be achieved; the direct spray surface of the jets can cover the surface of the cast product, so as to keep the cooling speed of any position of the cast product consistent, and ensure the quality of the finished steel.

Description

Continuous-casting of steel billet secondary cooling zone all standing cooling device
Technical field
The utility model relates to continuous-casting of steel billet, is specifically related to the cooling jet of secondary cooling zone in the continuous-casting of steel billet process.
Background technology:
At present, in the continuous-casting of steel billet process, no matter its secondary cooling zone is with gas, water cooling, still but with air cooling, nozzle location all is to be that 90 degree are provided with by angle between the two, this setup, in the spray cooling procedure, exist the cooling dead angle, i.e. the cooling velocity of spray cooling interface between the two, inconsistent with the speed of nozzle direct injection cooling surface, thereby cause the casting blank section lattice inconsistent, especially section is circular strand, and cooling velocity inconsistent (or inhomogeneous cooling is even) is more outstanding, have a strong impact on the finished steel quality, cause unnecessary economic loss to enterprise.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of continuous-casting of steel billet secondary cooling zone cooling device, and the direct injection cooling surface can cover casting billet surface, makes strand cooling velocity unanimity.
The utility model is achieved through the following technical solutions:
Continuous-casting of steel billet secondary cooling zone all standing cooling device, comprise be arranged in the secondary cooling zone, apart from the cooling jet on the same radius circumference of strand center, characteristics are cooling jet horizontal sextant angles between the two less than 90 degree, greater than 20 degree.
Described cooling jet horizontal sextant angle between the two is preferably 45 degree.
The utility model compared with prior art has following obvious advantage:
The utility model with cooling jet with horizontal sextant angle between the two less than 90 degree, be provided with greater than 20 degree, be that 45 degree are provided with generally with horizontal sextant angle, just can reach best spray cooling effect, nozzle direct injection face can cover casting billet surface, make the cooling velocity basically identical of the arbitrary position of strand, guaranteed the quality of finished steel.
Description of drawings:
Fig. 1 is the utility model sectional schematic diagram.
The specific embodiment:
As shown in Figure 1, the utility model comprise be arranged in the secondary cooling zone, apart from the cooling jet on the circumference of strand 2 center same radius 1, cooling jet 1 horizontal sextant angle between the two less than 90 the degree, greater than 20 the degree.Getting cooling jet horizontal sextant angle between the two in the present embodiment is 45 degree.Still as shown in Figure 1, the cooling medium that ejects from cooling jet 1 can cover casting billet surface uniformly, and having overcome the cooling jet horizontal sextant angle is the cooling dead angle problem that the 90 degree plans of establishment exist.

Claims (2)

1, continuous-casting of steel billet secondary cooling zone all standing cooling device, comprise be arranged in the secondary cooling zone, apart from the cooling jet on the circumference of strand center same radius, it is characterized in that: cooling jet horizontal sextant angle between the two less than 90 the degree, greater than 20 the degree.
2, continuous-casting of steel billet secondary cooling zone all standing cooling device as claimed in claim 1 is characterized in that: cooling jet horizontal sextant angle between the two is 45 degree.
