Description

The quick surface drying manufacture method of rail coating
Technical field
The present invention relates to Rail Production manufacturing process area, especially a kind of quick surface drying manufacture method of rail coating.
Background technology
Rail Surface application purpose is to improve the decay resistance and insulation against ground performance of rail, the application work of beam-and-rail rail Skill uses rail on-line spray scheme.The problem of existing coating process there are following:First, after coating spraying, because of steel Track surface temperature is low, and paint solvent evaporation rate is slow, and by working continuously, rhythm of production is limited, into during lower process because of coating table Face is not dry and produces substantial amounts of hurt;2nd, in the spraying scheme of production line, ultrasonic examination process must adopt water as Jie The water of matter, such as Rail Surface when entering spraying equipment can not surface drying completely, water not only reduces the temperature of Rail Surface, simultaneously Heavy damage can be produced to coating quality, it requires that rail enters dry tack free before spray booth;3rd, after spray coating, coating table The dry time produces influence to the processing of rear process, in the state of coating does not have surface drying, and rail, which enters next process, will cause to apply Layer major injury.Therefore, the present invention sets about from the temperature control in rail manufacturing process, the technique for optimizing production.
The content of the invention
The technical problems to be solved by the invention, which are to provide one kind, allows rail coating to realize quick surface drying, so as to be conducive to carrying The quick surface drying manufacture method of rail coating of the overall production quality of high rail and efficiency.
The technical solution adopted for the present invention to solve the technical problems is:The quick surface drying manufacture method of rail coating, including Following steps:A, progress steel rail universal rolling first;B, the rail feeding walking beam cooler that completion will be rolled, the rail temperature Control is between 60 DEG C -80 DEG C;C and then progress roll straightening, the winding song under bottom is rectified into by the rail in erectility; Rail Surface quality examination and ultrasonic examination after d, pair roller type aligning;E and then progress bidirectional hydraulic are mended and rectified;F, connect down To carry out on-line spray;G, completion processing scroll saw bore processing, and then stand closes steel stacking, the production of completion rail.
It is further that in the step b, the rail that rolling is completed, which enters, carries out cooling 2-3 hours after cold bed.
Be further, in the step c under it is winding bent when, every meter of flexibility by 0.1mm/m control.
Be further, in step d, by high-pressure blast by Rail Surface the ponding that produces in detection purged to prevent Only temperature drop is too fast.
It is further after above-mentioned surface area water purging, then to enter within 6-10 minutes the spraying described in step f Point carries out on-line spray.
Be further, after the completion of step f spraying, by one section of MID INFRARED surface heater heated from And improve coating temperature.
The beneficial effects of the invention are as follows:The present invention is accurately realized to rail by the optimization to Rail Production technique The control of temperature, on the premise of temperature range needed for ensureing Rail Production, allows temperature to be more suitable for the spraying and painting of coating The quick-drying of layer, so as to significantly improve the production efficiency of rail on the original basis, also ensure that the coating quality of coating. Among the coating process of beam-and-rail rail.
Embodiment
The quick surface drying manufacture method of rail coating, comprises the following steps:A, progress steel rail universal rolling first;B, will rolling The rail feeding walking beam cooler of completion, the rail temperature control is between 60 DEG C -80 DEG C;C and then progress roll straightening, Rail in erectility is rectified into the winding song under bottom;Rail Surface quality examination and ultrasound after d, pair roller type aligning Wave inspection;E and then progress bidirectional hydraulic are mended and rectified;F, followed by on-line spray;G, completion processing scroll saw bore processing, then Stand closes steel stacking, completes the production of rail.
The present invention, which is absorbed in, solves the influence that temperature is brought to coating quality.Normal process is to enter aligning below 40 DEG C Machine is aligned, because the phenomenon of thermal stress bending bounce-back, temperature occurs in the too high rail that can cause after aligning of straightening temperature Degree too low cool time is oversize and influences production efficiency.The present invention between 60 DEG C -80 DEG C, can protect rail temperature control Demonstrate,prove on the basis of later stage coating quick-drying, effectively prevent rail from the phenomenon of thermal stress bending bounce-back occur.General, it can also select The rail for selecting rolling completion enters cold bed progress cooling 2-3 hours.
General, the thermal stress bounce-back that rail occurs after being improved due to straightening temperature is brought to balance this change Influence, can typically select to increase drafts, with reference to practical experience, and every meter of flexibility is advisable by 0.1mm/m controls.
Enter the detection that inspection center carries out the projects such as ultrasonic examination after steel rail straightening, now using high-pressure blast pair Rail Surface in the detection the heart produce ponding progress purging prevent temperature drop too fast.After surface area water purging, 6-10 minutes Into spraying point, now Rail Surface temperature is positively retained at more than 56 DEG C substantially, it is ensured that late stage process is smoothed out.
After the completion of spraying, heating is carried out so as to improve coating temperature by one section of MID INFRARED surface heater, Accelerate the coating quick-drying time, so as to improve production efficiency.
The present invention accurately realizes the control to rail temperature by the optimization to Rail Production technique, is ensureing steel On the premise of temperature range needed for rail production, temperature is allowed to be more suitable for the spraying of coating and the quick-drying of coating, so that significantly The production efficiency for improving rail on the original basis, also ensure that the coating quality of coating.With China's high ferro market Increase rapidly, the present invention has very wide market promotion prospect.
