Abstract
The utility model discloses a kind of high line roughing cooling device of fast changeable, comprise the Water pipe bracket that level is installed and the curved cooling water pipe body being arranged on Water pipe bracket end, the described axis of rotation of curved cooling water pipe body and the dead in line of roll to be cooled, be installed with the snap joint of docking with oral siphon along the uniform nozzle of its length inside described cooling water pipe body outside it; Cooling water pipe structure of the present utility model is comparatively simple, makes processing cost lower; Large arc length can improve cooling effectiveness; Flat water spray makes whole groove obtain Homogeneous cooling, and is easy to cleaning when delivery port blocks; Water inlet exports near milling train, makes discharge pressure and flow herein maximum, can more fast and effeciently pair roller groove cooling.
Description
Technical field
The utility model relates to a kind of high line roughing cooling device technical field, particularly relates to a kind of high line roughing cooling device of fast changeable.
Background technology
Heat Working Rolls peels off and is caused by contact fatigue, and peeling off of occurring in production is most caused by roll surface crackle, and when work roll contacts with high temperature billet steel, its roll surface temperature can be elevated to 500 ~ 600 DEG C; When it touches cooling water, the temperature of working roll drops to rapidly less than 100 ~ 150 DEG C again.This periodic heating and cooling make working roll roll surface create the temperature field of change, thus create obvious cyclic stress, and when thermal stress exceedes the fatigue limit of material, roller surface just produces tiny weblike heat crackle, namely chaps.From rolling mill practice aspect, guarantee the normal input of cooling water, in use must strengthen the management of breaker roll cooling jet, ensure that nozzle does not block, the water yield is enough, guarantees that the temperature of roll controls within normal range (NR), alleviates the heat fatigue of roll, improve roll campaign, reduce roller consumption.Because current steel rolling roughing mill uses prestressed rolling mill, and be not easy to arrange with the groove water pipe that waters of the rolling mill roll reversing rod, roll groove cooling effect is bad.
The damage caused owing to cooling bad breaker roll directly has influence on the surface quality of finished product; For alleviating the impact on quality, must frequently roll change, and frequent roll change had both delayed the production time, have impact on output, caused again roller to consume high, added production cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high line roughing cooling device of fast changeable, can improve cooling effectiveness, quick-replaceable, is easy to cleaning, can more fast and effeciently pair roller groove cooling.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of high line roughing cooling device of fast changeable, comprise the Water pipe bracket that level is installed and the curved cooling water pipe body being arranged on Water pipe bracket end, the described axis of rotation of curved cooling water pipe body and the dead in line of roll to be cooled, be installed with the snap joint of docking with oral siphon along the uniform nozzle of its length inside described cooling water pipe body outside it.
The angle of the circular arc that described cooling water pipe body is corresponding is 105 °, evenly arranges 8 nozzles inside it, and the spacing between adjacent nozzle is 4mm.
The angle of the circular arc that described cooling water pipe body is corresponding is 45 °, evenly arranges 5 nozzles inside it, and the spacing between adjacent nozzle is 4mm.
Described snap joint to be welded on outside cooling water pipe body and through with the inner chamber of cooling water pipe body.
The beneficial effect adopting technique scheme to produce is: cooling water pipe structure of the present utility model is comparatively simple, makes processing cost lower; Large arc length can improve cooling effectiveness; Flat water spray makes whole groove obtain Homogeneous cooling, and is easy to cleaning when delivery port blocks; Water inlet exports near milling train, makes discharge pressure and flow herein maximum, can more fast and effeciently pair roller groove cooling.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two;
In the accompanying drawings: 1, Water pipe bracket; 2, snap joint; 3, cooling water pipe body.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment one: in order to solve the bad problem of cooling effect of existing high line roughing cooling device, the utility model provides a kind of high line roughing cooling device as fast changeable, comprise the Water pipe bracket 1 that level is installed and the curved cooling water pipe body 3 being arranged on Water pipe bracket 1 end, the described axis of rotation of curved cooling water pipe body 3 and the dead in line of roll to be cooled, be installed with the snap joint 2 of docking with oral siphon along the uniform nozzle of its length inside described cooling water pipe body 3 outside it.
The angle of the circular arc of described cooling water pipe body 3 correspondence is 105 °, evenly arranges 8 nozzles inside it, and the spacing between adjacent nozzle is 4mm, and described snap joint 2 to be welded on outside cooling water pipe body 3 and through with the inner chamber of cooling water pipe body 3.
Embodiment two, the difference between the present embodiment and embodiment one is the curved angle of cooling water pipe body, and the angle of the circular arc of cooling water pipe body 3 correspondence of the present embodiment is 45 °, evenly arranges 5 nozzles inside it, and the spacing between adjacent nozzle is 4mm.
In embody rule process, Water pipe bracket level is installed, the cooling water pipe body of arc is installed at its end, arc cooling water pipe body two sections, for closing filling, fixedly mounts snap joint, is connected cooling water pipeline by snap joint with flexible pipe outside it, the nozzle arranged inside cooling water pipe body is flat structure, and cooling water pipe body can select different curved angle according to different size roll, its structure is comparatively simple, makes processing cost lower; Large arc length can improve cooling effectiveness; Flat water spray makes whole groove obtain Homogeneous cooling, and is easy to cleaning when delivery port blocks; Water inlet exports near milling train, makes discharge pressure and flow herein maximum, can more fast and effeciently pair roller groove cooling.
