Abstract
The utility model provides a kind of built-in water-cooled nozzle of rolling, relate to metallurgical steel rolling field, comprise the guide groove body of water-cooled nozzle, guide groove body is provided with nozzle guiding aperture, described guide groove body is also provided with a pair deflector roll, be respectively the upper deflector roll and lower guide roll that are arranged on the upper and lower both sides of nozzle guiding aperture, the roll surface of described upper deflector roll and lower guide roll is equipped with pass, described upper deflector roll and lower guide roll are all arranged on guide groove body by eccentric shaft and eccentric bushing.The utility model overcomes jitter phenomenon in rolled piece running and the resistance of motion, and workpiece motion s more easily, steadily, is avoided rolled piece to produce with guiding hole wall and rubbed, thus the surface damage avoiding product to cause because of friction; When deflector roll may wear to certain, only need change deflector roll, nozzle body still can continue to use, and extends the service life of nozzle, reduces production cost.
Description
Technical field
The utility model relates to metallurgical steel rolling field, particularly relates to a kind of built-in water-cooled nozzle of rolling.
Background technology
Existing structure as shown in Figure 1 and Figure 2, wherein, 1: body, 2: plug screw, 3: end cap, 4: bolt.
The defect existed:
1., after rolled piece enters nozzle, run under > 65M/S speed state.The motion of rolled piece with jitter motion form objective reality, rubs so inevitably guide hole wall to produce with guide groove and cause product surface to damage (also referred to as pulling).Especially produce the higher product of surface quality requirements, the friction phenomenon in motion can not reach the requirement ensureing surface quality.
2. due to rolled piece shake running status and inevitably produce friction phenomenon with nozzle guide hole wall, cause the resistance of motion in rolled piece running and produce and pile steel accident.
3. bullport easily produces wearing and tearing because rubbing, and causes entirety to scrap when using after bullport wearing and tearing.
Utility model content
The purpose of this utility model is to provide a kind of built-in water-cooled nozzle of rolling, to solve the problems of the technologies described above.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of built-in water-cooled nozzle of rolling, it is characterized in that: the guide groove body comprising water-cooled nozzle, guide groove body is provided with nozzle guiding aperture, described guide groove body is also provided with a pair deflector roll, be respectively the upper deflector roll and lower guide roll that are arranged on the upper and lower both sides of nozzle guiding aperture, the roll surface of described upper deflector roll and lower guide roll is equipped with pass, and described upper deflector roll and lower guide roll are all arranged on guide groove body by eccentric shaft and eccentric bushing.
Described pass is " V " type groove that ring is located on deflector roll roll surface, and the angle of " V " type groove is 120 °, and the bottom land of " V " type groove is arranged to circular arc chamfering.
After rolled piece enters nozzle guiding aperture, under in nozzle, the pass effect of rolling movement and deflector roll done by deflector roll, rolled piece is nestled and is run in the pass of deflector roll (upper deflector roll and lower guide roll), overcome the jitter phenomenon in rolled piece running and the resistance of motion, the motion of rolled piece is become easily, steadily, avoids the generation of production accident.Nestle due to rolled piece and run in the pass of deflector roll, avoid rolled piece to produce with guiding hole wall and rub, thus the surface damage avoiding product to cause because of friction.
The beneficial effects of the utility model are:
The utility model overcomes jitter phenomenon in rolled piece running and the resistance of motion, and workpiece motion s more easily, steadily, is avoided rolled piece to produce with guiding hole wall and rubbed, thus the surface damage avoiding product to cause because of friction; When deflector roll may wear to certain, only need change deflector roll, nozzle body still can continue to use, and extends the service life of nozzle, reduces production cost.
