Abstract
The utility model discloses a water cooling roller, which comprises a core pipe (1) in the roller and a spiral blade (2). The utility model is characterized in that the spiral blade (2) is a long cylindrical spiral blade which is wound in a constant-pitch spiral way and is fixed on the surface of the core pipe (2), and in addition, a water return hole (3) is arranged in the tail end diameter direction of the coming water of the core pipe (2). The utility model can prevent the defect of blockage caused by impurities containing in the circulation cooling water and scale formation of the circulation cooling water. The service life of the water cooling roller is prolonged from the original six months to 12 months, the temperature reducing replacing times and time of the water cooling roller accidents can be reduced, and the production rate can be effectively improved.
Description
Technical field
The utility model relates to a kind of continuous annealing furnace parts, relates in particular to a kind of water cooled rolls.
Background technology
Cold-reduced silicon steel mill continuous annealing unit is divided into preheating section, heating zone, soaking zone and pressure cooling section at present, and water cooled rolls is applied in heating zone, and the processing requirement temperature is at 1000-1200 ℃, and water cooled rolls plays a supportive role in the heating zone stove.In order to prevent that water cooled rolls from being burnt the curved damage that causes under hot conditions, the band steel is produced scuffing, special add a core pipe in water cooled rolls inside and adhere to superincumbent screw-blade, and pass to recirculated cooling water and cool off water cooled rolls, make it works better under hot conditions.And the screw-blade structure of water cooled rolls inside be the continuous welding of individual leaflet sheet together, adopt welded type to be fixed on the water-cooled roller core pipe simultaneously.End at water cooled rolls has water-in, the core pipe internal helicoid blade of flowing through, and the water outlet from the core pipe flows out at last, plays the effect of water cooled rolls cooling protection.
Because water cooled rolls works under 1000-1200 ℃ of hot conditions, cooling circulating water is in the inner long-time fouling of core pipe in addition, is easy to cause that the screw-blade gap is stopped up, current are not smooth, makes water cooled rolls burn curved and damages.On the other hand because water cooled rolls internal helicoid blade is the individual blade spot welded type, under the impact of being vibrated for a long time with the pressure of cooling circulating water, solder joint ftractures easily, causing the part screw-blade to distort comes off, because water cooled rolls internal helicoid blade space is narrow and small, the screw-blade that comes off is easy to stop up the screw-blade gap, causes current freely not cause water cooled rolls high temperature to damage.
The utility model content
For overcoming the above-mentioned defective that existing apparatus exists, technical problem to be solved in the utility model is to provide a kind of water cooled rolls that can prevent effectively that the inner obstruction of core pipe, water cooled rolls from damaging.
Comprise core pipe and screw-blade in the roller, it is characterized in that: screw-blade is a cylindrical elongated helical blade uniform pitch spiral winding and is fixed on the core tube-surface, and have backwater hole on core Guan Laishui end diameter direction.
Fix with the core sealing of tube because screw-blade is whole, increased the fixation degree of screw-blade and core pipe, screw-blade and core pipe contact area reduce simultaneously, increase the trickling space of recirculated cooling water, can effectively prevent to contain in the recirculated cooling water impurity and recirculated cooling water structure dirt and the drawback of obstruction; Increased to 12 month by original 6 months work-ing life; Reduce the cooling of water cooled rolls accident and change number of times and time, boost productivity.
Description of drawings
Fig. 1 is the utility model structure water cooled rolls synoptic diagram;
Wherein, 1 core pipe, 2 screw-blades, 3 backwater holes.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
The present invention is applied in 1000-1200 ℃ of working of a furnace of continous way annealing unit.
The water cooled rolls screw-blade that uses at present connects as individual leaflet sheet series spot welding formula, is welded to simultaneously on the core pipe, and does not also have backwater hole on the core pipe 1 at present.
As shown in Figure 1: it is that 14mm, material are that cylindrical elongated helical blade 2 uniform pitchs (100mm) spiral of 1Gr18Ni9Ti twines and screw-blade 2 is carried out the set a distance spot welded type and is weldingly fixed on core pipe 1 surface that screw-blade is made by a diameter, drill diameter is 3 backwater holes 3 of 6mm in the equal angles on the water end diameter direction (being 120 degree with diametric(al)) of coming of core pipe 1, increase the backwater space of recirculated water, reduce and stop up.
Claims (3)
1. water cooled rolls, comprise core pipe (1) and screw-blade (2) in the roller, it is characterized in that: screw-blade (2) is that a cylindrical elongated helical blade uniform pitch spiral twines and is fixed on core pipe (2) surface, and comes to have backwater hole (3) on the water end diameter direction at core pipe (2).
2. water cooled rolls according to claim 1 is characterized in that: described backwater hole (3) is 3, is 120 degree with diametric(al).
3. water cooled rolls according to claim 1 and 2 is characterized in that: described screw-blade (2) diameter is 14mm, and pitch is 100mm.
