Description
Technical field
The present invention relates to a kind of cooling device.
Background technology
Strand with the liquid heart out enters secondary cooling zone from crystallizer, and cooling water is sprayed directly on on strand the further task of cooling and the whole solidifications of completion.Therefore, slab quality and casting machine productivity are largely decided by secondary cooling intensity, the distribution of cooling water and control, the type of cooling, the level of two cold-zone equipment.
Secondary cooling is to carry out water-spraying control to leaving crystallizer band liquid heart strand, so that strand solidifies completely, and controls casting blank surface temperature uniformly to decline in throwing direction.
It is that strand is cooled down using directly water spray in two cold-zones, distance between intensity of cooling, cooling water inflow, hydraulic pressure, water temperature, nozzle arrangements and arrangement, nozzle and strand etc. all has a direct impact to strand radiating.Reasonable cooling system should be determined according to steel grade and section requirement.
The casting blank shell thickness pulled out from crystallizer gradually increases in two cold-zones, and it is relatively thin green shell just to have left crystallizer, and injection flow rate is big, so that green shell is thickened rapidly.As strand is moved in two cold-zones, shell thickness increases, and injection flow rate should be reduced gradually, and cooling length is gradually increased.Therefore, two cold-zones are divided into some cooling sections, each cooling section individually carries out water rate control, workpiece cooling effect and quality are seemed and is even more important.
The content of the invention
The present invention is in order to solve the cooling device that problem above provides a kind of simple structure, uniform spraying, sub-sectional cooling.
The technical scheme is that：Including outer arc shower, inner arc shower, side arc shower one, side arc shower two, nozzle, nozzle carrier and water inlet, described outer arc shower, inner arc shower, side arc shower one, side arc shower two is symmetrically distributed in around strand, water inlet and some nozzle carriers are welded with every described shower, nozzle, described outer arc shower, inner arc shower, side arc shower one, the bend pipe radian of side arc shower two is consistent, it is separated by identical radian perforate on four described showers, each tapping is welded with nozzle carrier and nozzle, described nozzle is towards strand, closed with steel plate every described shower upper end, lower end is welded with plug.
Simple structure of the present invention, easy to use, shower is symmetrical and being divided into some sections can respectively control nozzle to spray corresponding flow and angle, and water atomization is good, and drop diameter is small, and cooling is uniform；Nozzle outlet diameter is big, is not easily blocked；Nozzle quantity is few, the bigger strand area of uniform fold, using water wisely；Flow adjustment range is big, cooling of the present invention suitable for all steel grades.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
1 is outer arc shower in figure, and 2 is side arc shower one, and 3 is side arc shower two, and 4 is inner arc shower, and 5 is water inlet, and 6 is nozzle carrier.
Specific embodiment
A kind of cooling device, including outer arc shower 1, inner arc shower 4, side arc shower 1, side arc shower 23, nozzle 7, nozzle carrier 6 and water inlet 5, described outer arc shower 1, inner arc shower 4, side arc shower 1, side arc shower 23 is symmetrically distributed in around strand, water inlet 5 and some nozzle carriers 6 are welded with every described shower, nozzle 7, described outer arc shower 1, inner arc shower 4, side arc shower 1, the bend pipe radian of side arc shower 23 is consistent, it is separated by identical radian perforate on four described showers, each tapping is welded with nozzle carrier 6 and nozzle 7, described nozzle 7 is towards strand, closed with steel plate every described shower upper end, lower end is welded with plug.
