Abstract
The utility model relates to a rapid cooling device for seamless special pipes formed by on-line hot rolling and rolling. The device is characterized by comprising a frame (1), wherein transporting roller sets (2) are arranged at the front and rear sides of the frame (1), the frame (1) is further provided with a plurality of horizontally placed transporting bars (3), a revolving shaft (4) is arranged above a part between the transporting roller sets (2) and is externally sleeved with a spray pipe (6); meanwhile, the frame (1) is further provided with an infrared thermometer connected with a PLC (Programmable Logic Controller), and the PLC is connected with the transporting bars (3). The rapid cooling device for the seamless special pipes formed by hot rolling and rolling on line is capable of quickly cooling and preventing the intercrystalline crack of the tissues of the seamless special pipes.
Description
Technical field
The utility model relates to be shaped the online quickly cooling device of seamless heterotype pipe of a kind of hot rolling, roll-in, and it can carry out fast cooling to the steel pipe passing through on hot rolling reducing mill stand.
Background technology
At present, seamless heterotype steel pipe adopts cold-drawing technology processing mostly, but cold-drawn processing technology is comparatively complicated, need the operations such as system head, annealing, pickling, cold-drawn, aligning, and cold-drawn is sliding friction, required Drawing Force is larger, easily pull the surfaces externally and internally of steel pipe, simultaneously not only energy consumption is high for cold-drawn manufacture method, and recovery rate of iron is low, and acid washing phosphorization etc. also can bring environmental pollution.
Therefore, need to carry out the online processing technology being shaped of high temperature to seamless heterotype pipe, but how the seamless heterotype Guan Cong hot rolling frame of high temperature is delivered to the temperature that is cooled fast to regulation before forming machine, to avoid seamless heterotype tubing intercrystalline crack, just become a difficult problem.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one to lower the temperature rapidly, avoids be shaped the online quickly cooling device of seamless heterotype pipe of hot rolling, the roll-in of seamless heterotype tubing intercrystalline crack.
The purpose of this utility model is achieved in that
The utility model hot rolling, be shaped the online quickly cooling device of seamless heterotype pipe of roll-in, comprise frame, the both sides, front and back of described frame are provided with haul roller group, the haul roller that this haul roller group is arranged by multiple front-back staggereds forms, in described frame, be also provided with the haul bar of multiple horizontal positioned, wherein each haul bar is all located between adjacent two haul rollers, and one end and the frame of haul bar are hinged, seamless heterotype pipe can be moved to transport in one end that haul bar is not connected with frame, top between described haul roller group is provided with a rotating shaft, one end of described rotating shaft and the output shaft of motor fix, and the bottom of this motor is fixed in frame by underframe, the outer cover of described rotating shaft has shower, in frame, be also provided with infrared radiation thermometer simultaneously, described infrared radiation thermometer is connected with PLC controller, described PLC controller is connected with haul bar.
This hot rolling, the roll-in quickly cooling device of seamless heterotype pipe that is shaped online has the following advantages compared with technology in the past:
This hot rolling, roll-in is shaped the quickly cooling device of seamless heterotype pipe online by being arranged between hot rolling frame and forming machine, hot rolling frame high temperature seamless heterotype pipe is out transported backward by the cooperation of haul roller group and haul bar, by shower, its online spray is carried out to fast cooling simultaneously, and infrared radiation thermometer in frame passes to PLC controller after recording the temperature of seamless heterotype pipe, PLC controller is controlled the translational speed of haul bar again, thereby control the transporting velocity of seamless heterotype pipe on quickly cooling device, and then the temperature that guarantees seamless heterotype pipe can reach prescribed limit in the time that it transports quickly cooling device.
Accompanying drawing explanation
Fig. 1 is be shaped the online structural representation of quickly cooling device of seamless heterotype pipe of the utility model hot rolling, roll-in.
Wherein: frame 1, haul roller group 2, haul bar 3, rotating shaft 4, motor 5, shower 6.
The specific embodiment
Participate in Fig. 1, the utility model relates to a kind of hot rolling, be shaped the online quickly cooling device of seamless heterotype pipe of roll-in, it comprises frame 1, the both sides, front and back of described frame 1 are provided with haul roller group 2, the haul roller that this haul roller group 2 is arranged by multiple front-back staggereds forms, in described frame 1, be also provided with the haul bar 3 of multiple horizontal positioned, wherein each haul bar 3 is all located between adjacent two haul rollers, and one end of haul bar 3 and frame 1 are hinged, the seamless heterotype pipe by its top can be moved to transport in one end that haul bar 3 is not connected with frame 1, top between described haul roller group 2 is provided with a rotating shaft 4, the output shaft of one end of described rotating shaft 4 and motor 5 fixes, and the bottom of this motor 5 is fixed in frame 1 by underframe, the outer cover of described rotating shaft 4 has shower 6, described shower 6 carries out On-line accelerated cooling for passing into cooling water to seamless heterotype pipe.
In frame 1, be also provided with infrared radiation thermometer simultaneously, described infrared radiation thermometer is connected with PLC controller, for the temperature of the seamless heterotype pipe recording is passed to PLC controller, the translational speed of described PLC controller control haul bar 3, thereby control the transporting velocity of seamless heterotype pipe on quickly cooling device, and then guarantee that the temperature of seamless heterotype pipe can reach prescribed limit in the time that it transports quickly cooling device.
