Summary of the invention
The purpose of this utility model is exactly for above-mentioned defect, and a kind of hot-rolling finishing mill group inlet side-guiding-board is provided, and has overcome cold rolling stalk seal defect of the prior art and foreign matter and has been rolled into defect, has improved finished product rate, has guaranteed the production direct motion.
For achieving the above object, the hot-rolling finishing mill group inlet side-guiding-board that the utility model is designed, comprise guide plate liner plate and guide plate rebound, the Shang Yanchu of described guide plate liner plate is provided with the guide plate liner plate cooling water pipe with water spout, and the sidepiece of described guide plate rebound is welded with baffle plate.
Further, described guide plate liner plate cooling water pipe is fixed on the gland of described guide plate liner plate top.
Further, be provided with a plurality of water spouts on described guide plate liner plate cooling water pipe, water spout passes gland covers on the guide plate liner plate water of water spout ejection.
The utility model has the advantage of: on the one hand by the baffle plate of two flipper guide rebound sidepiece welding at hot-rolling finishing mill group entrance side, while guaranteeing the sputter of transition beam cooling water, can not be bound to belt steel surface, thereby guarantee that the band steel can not form the topical hypothermia district, can not form local high spot after rolling; The Shang Yanchu of guide plate liner plate is provided with the guide plate liner plate cooling water pipe with water spout on the other hand, the water sprayed is covered on the guide plate liner plate but is unlikely to rebound to belt steel surface to form Local cooling, reduce guide plate liner plate temperature, between broken ring thermal state metal, produce the effect of similar " friction welding (FW) ", thereby reduced the dross generation, reduced the flame cutting times, effectively direct motion production, saved production cost; Therefore overcome that cold rolling stalk in existing production technology prints defect and foreign matter is rolled into defect, improved lumber recovery, guaranteed the unobstructed of the continuity of production process and logistics.
The accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is axonometric drawing of the present utility model.
In figure, each parts label is as follows: guide plate 1, guide plate liner plate 1.1, guide plate rebound 1.2, gland 2, guide plate liner plate cooling water pipe 3, baffle plate 4, transition beam 5, water spout 6.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, 3, the guide plate 1 of hot-rolling finishing mill group entrance side comprises the guide plate liner plate 1.2 of vertical direction and the guide plate rebound 1.2 of horizontal direction.
Therefore in order to prevent that transition beam 5 cooling waters are splashed to belt steel surface, the sidepiece at the guide plate rebound 1.2 of both sides respectively is welded with baffle plate 4.By spacing and the scope of calculating the transition beam cooling water, determine the baffle dimensions scope, while guaranteeing the sputter of transition beam cooling water, can not be bound to belt steel surface, guarantee that the band steel can not form the topical hypothermia district, can not form local high spot, thereby improve the quality of product after rolling.
Simultaneously, the Shang Yanchu of guide plate liner plate 1.1 is provided with the guide plate liner plate cooling water pipe 3 with water spout 6, guide plate liner plate cooling water pipe 3 is fixed on the gland 2 of guide plate liner plate 1.1 tops, a plurality of water spouts 6 on guide plate liner plate cooling water pipe 3 pass gland 2 covers on guide plate liner plate 1.1 water of water spout 6 ejections, and by pressure and the angle calculation of cooling water, water spout quantity reasonable in design and water spout model, make the injection water covering of the fan just cover the guide plate liner plate but be unlikely to rebound to belt steel surface and form Local cooling, can reduce like this guide plate liner plate temperature, between broken ring thermal state metal, produce the effect of similar " friction welding (FW) ", thereby reduced the dross generation, reduced the flame cutting times, effectively direct motion production, saved production cost.
It is below the design of concrete finish rolling inlet side-guiding-board
