Abstract
The utility model provides a water pipe inner lining of a cooler with hot rolling wire and bar materials. The inner cavity composed of inner lining is an interlaced hollow circular cone and a hollow cylinder. The included angle between the oblique line and axial line of the hollow circular cone is above 10 degrees. Compared with the prior art, the utility model causes the frequent change of the flow pressure in the cooling pipe through the cavity angle formed by expanding inner lining and alternation between the hollow circular cone and the hollow cylinder, thus enforcing the frequent heat energy exchange of cooling water and high-temperature steel materials and improving cooling effect. Additionally, the flow pressure is gradually declining by a plurality of transformation under the influence of the inner lining, thus to some extent preventing the cooled water in the cooling pipe from scurrying out of the cooler.
Description
One, technical field
The utility model relates to a kind of part of cooling system, relates in particular to a kind of hot rolling line bar cooling tube liner of rolling machinery technical field.
Two, background technique
In the hot-strip cooler; the effect of cooling tube liner mainly contains two: the one, prevent the wearing and tearing of cooling tube; because the high temperature steel can pass in cooling tube with fast speeds; can produce bigger impulse force to the cooling tube inwall; of long duration, cooling tube has quite serious wearing and tearing, behind the use liner; need only change the liner of wearing and tearing, just can play protective action cooling tube.The 2nd, the change by the liner cavity shape changes hydraulic pressure, thereby impels the steel of high temperature and cooling water to exchange heat energy.
Existing hot rolling line bar cooler water pipe liner as shown in Figure 1, as seen from the figure, this cooling tube liner cavity, its shape resembles by a plurality of bellmouth orifices and forms along connecing, and the inclined-plane inclination of bellmouth orifice is very little, cause the variation in water pressure of current little, be unfavorable for promoting high temperature steel and cooling water to carry out heat exchange.
Three, summary of the invention
In order to overcome the shortcoming of above-mentioned cooler water pipe liner, the utility model provides a kind of improved hot rolling line bar cooler water pipe liner.The variation of the angle by increasing liner, make the frequent change of current hydraulic pressure in the cooling tube, thereby force frequent exchange heat energy between cooling water and the high temperature steel, further improve cooling effect, on the other hand, the hydraulic pressure of current by transformation repeatedly, diminishes under the effect of liner gradually, can prevent the interior cooling water of the cooling tube cooler of scurrying out so to a certain extent.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hot rolling line bar cooler water pipe liner is made of high-abrasive material, and the internal cavities that described hot rolling line bar cooler water pipe liner constitutes is staggered hollow cone and hollow cylinder.
The purpose of this utility model can also further realize by following technical solution:
Foregoing hot rolling line bar cooler water pipe liner, the awl oblique line of described circular cone and the angle between the axis of cone line are more than 10 degree.
Foregoing hot rolling line bar cooler water pipe liner has certain radian face between the awl inclined-plane of described hollow cone and the bottom surface.
Compared with prior art, the utlity model has following beneficial effect: strengthen the variation of liner angle, make the frequent change of current hydraulic pressure in the cooling tube, thereby force frequent exchange heat energy between cooling water and the high temperature steel, further improve cooling effect.The hydraulic pressure of current by transformation repeatedly, diminishes under the effect of liner gradually, can prevent the interior cooling water of the cooling tube cooler of scurrying out so to a certain extent.Be provided with certain radian face in addition between the awl inclined-plane of circular cone and bottom surface, when current travelled forward, a spot of water can form eddy current at the radian place, can further promote heat exchange like this.
Four, description of drawings
Fig. 1 is the sectional drawing of existing hot rolling line bar cooler water pipe liner;
Fig. 2 is the sectional drawing of the utility model embodiment's hot rolling line bar cooler water pipe liner;
Five, embodiment
According to an embodiment of the present utility model shown in Figure 2, shown in the internal cavities of hot rolling line bar cooler water pipe liner 1, formed along connecing successively by hollow cone 2 and hollow cylinder 3, the awl oblique line of circular cone and the angle between the axis of cone line are more than 10 degree, and optimum angle is that 15 degree are between 20 degree.The opening that circular cone is big and the inlet of steel are connected, being convenient to steel enters, when current flow to hollow cylinder from hollow cone, because diameter diminishes suddenly, then the pressure of current became big, when moving forward, when flowing through the hollow cone part, water flow pressure diminishes, and so analogizes, what hydraulic pressure did not stop changes, and can impel cooling water and high temperature steel that heat exchange takes place continually like this.Certainly hollow cone 2 and hollow cylinder 3 not necessarily change by rule, such as can being that continuous two relative hollow cones connect and are connected with a hollow cylinder, also can increase the number of hollow cone and hollow cylinder, so also can realize frequently changing the effect of hydraulic pressure.Be provided with certain radian face 4 in addition between the awl inclined-plane of circular cone 2 and bottom surface, when current travelled forward, a spot of water can form eddy current at the radian place, can further promote heat exchange like this.
