A kind of push away the method rolling shaping rail, process chart as shown in Figure 8,
Step A: steel billet blank prepares, and feeding, front and back steel billet is end to end.
Step B: steel billet 8 pushing tow to heater 2 is heated to rolling temperature by thrust device 1, thrust promotes the speed of steel billet 8 identical with the firing rate of the sensing heating gate 15 of heater 2.
Step C: thrust device 1 pushing tow, steel billet 8 rolls through roll device.
Relate to track and push away the deformation distribution rolling deformation process:
(A0-A1)/A0*100% is not more than 30%
(A1-A2)/A1*100% is not more than 10%
(A2-A3)/A2*100% is not more than 5%
A0 is steel billet cross-sectional area.
A1 is that a time pushes away rail profile area when rolling.
A2 is that two passages push away rail profile area when rolling.
A3 is that three passages push away rail profile area when rolling.
A4, A5 are rail profile area during aligning finishing.
Step D: thrust device 1 pushing tow, owing to front and back's steel billet is end to end, described previous joint steel billet 8 promotes later section steel billet 8 through apparatus for shaping shaping.
(A3-A4)/A3*100% is not more than 1%
A3 is that three passages push away rail profile area when rolling.
A4, A5 are rail profile area during aligning finishing.
Step E: thrust device 1 pushing tow, steel billet 8 is aligned through straightener.
A4=A5
A3 is that three passages push away low floor vehicle rail profile area when rolling.
A4, A5 are low floor vehicle rail profile area during aligning finishing.
Step F: steel billet 8 is again heated to hardening heat by the sensing heating gate 15 of reheater 5.
Step G: spray liquid mist of quenching, make finished surface Quenching Treatment through atomization jetting device 6.
During pushing and withstanding, roll device need to fill appropriate high-temperature lubricant to reduce roll wear.
Finished product need to be through every detection with packaging shipping after reaching parameters.
Often the change of set roll device formed pass area should meet metal rolled deformation coefficient requirement.
When the number of described roll device 3 is three, when the number of described shaping straightener 4 is two, now have five set rollers, the area that the roller of first to fourth set surrounds is gradually reduced, play the effect of roll compacting, shaping, 4th is consistent with the area that the 5th set roller surrounds, mainly its aligning and the effect of adjustment.4th and the 5th set roller between distance more than front four set rollers often overlap between distance.Often between set roller, guider is set, such as directive wheel, help steel billet to enter often and overlap between roller.Described guider can be arranged on top, bottom or the left and right sides.The initial part of this equipment arranges steel billet frame, described in complete position finished product material frame be set.This technical characterstic, few with traditional approach specific investment, organization of production is flexible, advantage of lower cost.It is suitable for medium-sized and small enterprises to use.Change pass compound mode and structure, other kind shaped steel similar can be produced.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
