A kind of production method of the leveling apparatus and its smoothing wheel of station boiler band steel band, it is intended to the problem of smoothing the gap inconvenience adjusting of wheel in the excessively smooth and existing leveling apparatus in surface for solving the problems, such as band steel band that existing leveling apparatus is processed.The leveling apparatus includes smoothing wheel, fixed frame and hydraulic system, and smoothing wheel includes upper pressure wheel and lower pressure wheel, and upper pressure wheel rotation is set on fixed frame, and the piston rod Connection Bracket of hydraulic system, lower pressure wheel is in the lower section of upper pressure wheel, and the surface for smoothing wheel sets annular knurl lines.The production method are as follows: a, blanking；B, quenched；C, machine adds；D, annular knurl；E, surface high frequency quenches.The present invention sets annular knurl lines on the surface of smoothing wheel, and the band steel belt surface after making smoothing also has annular knurl lines, avoids the surface of band steel band excessively smooth.The upper pressure wheel of leveling apparatus is driven by hydraulic system and is moved up and down, and realizes the adjusting to the gap between upper pressure wheel and lower pressure wheel, is suitable for the smoothing operation of various sizes of band steel band.
Description
Technical field:
The present invention relates to the manufacture fields of station boiler band steel band, and in particular to a kind of smoothing dress of station boiler band steel band
The production method for setting and its smoothing wheel.
Background technique:
Currently, domestic station boiler water water wall section generally carries out in such a way that band steel adds steel pipe docking continuously to weld
Welding, coating coating in outer surface carries out protective treatment after the completion of welding.Band steel for welding needs to carry out at smoothing before welding
Reason.The smoothing wheel surface of existing band steel leveling apparatus is smooth surface, and after smoothing, band steel surface is excessively bright；And steel
The roughness for needing to have certain when material external coating coating, otherwise surface covering easily falls off, and causes to corrode.According to sandblasting
Band steel surface after processing smoothing, due to the limitation of size, the disadvantages such as big, higher cost that there are processing difficulties, production efficiency are low.
Meanwhile the gap between existing band steel leveling apparatus upper pressure wheel and lower pressure wheel is not easy to adjust, and is smoothing various sizes of band steel
When band, need to artificially it manually adjust, it is cumbersome and time consuming, it is unsatisfactory for the requirement efficiently produced.
Summary of the invention:
The present invention is to overcome drawbacks described above, provides a kind of leveling apparatus of station boiler band steel band and its system of smoothing wheel
Make method, first technical problem to be solved is to be provided with annular knurl lines on the surface of smoothing wheel, solves existing school
The excessively smooth technical problem in the surface for the band steel band that leveling device is processed；Its second technical problem to be solved is logical
Cross setting moveable upper pressure wheel, solve smoothed in existing leveling apparatus wheel gap be not easy to adjust the technical issues of.
The leveling apparatus of station boiler band steel band of the invention, technical solution used for the above purpose are:
Including smoothing wheel, fixed frame and hydraulic system, the smoothing wheel includes upper pressure wheel and lower pressure wheel, and the upper pressure wheel rotation is set to solid
Determine on frame, the piston rod Connection Bracket of the hydraulic system, the lower pressure wheel is in the lower section of upper pressure wheel, the smoothing wheel
Surface sets annular knurl lines.
As a further improvement of the present invention, the dimensional height h of the annular knurl lines of the smoothing wheel is 0.2~0.5mm, section
It is 0.9~1.5mm away from p.
The production method of the smoothing wheel of leveling apparatus of the invention, the technical solution of use are, comprising the following steps:
A, blanking；
B, quenched；
C, machine adds；
D, annular knurl；
E, surface high frequency quenches.
As a further improvement of the present invention, the smoothing turbine add-on type is placed in radio-frequency induction coil outside carrying out
Surface heating, induction heating frequency 100kHz~200kHz heating time 1~2 minute, take out oil quenchinng to 400 DEG C or less
It is fuel-displaced, it is air-cooled to room temperature.
As a further improvement of the present invention, the smoothing wheel blanking is placed in sealed box type quenching furnace, and surface is high in step e
The hardening heat of frequency quenching is controlled at 840~870 DEG C.
As a further improvement of the present invention, after step e, by smoothing wheel heat preservation 1~2 hour, oil quenchinng is taken out extremely
300 DEG C or less.
As a further improvement of the present invention, smoothing wheel after cooling will be quenched to be placed in chamber type annealing stove, tempering temperature
It is air-cooled to keep the temperature taking-up in 2~3 hours at 570~610 DEG C for control.
As a further improvement of the present invention, the surface hardness after surface high frequency quenching treatment is controlled in HRC48~55, is quenched
Saturating depth 2mm or more.
The beneficial effects of the present invention are: the present invention is provided with annular knurl lines on the surface of smoothing wheel, so make to be taken turns by smoothing
Band steel belt surface after smoothing also has annular knurl lines, avoids the surface of band steel band excessively smooth.Leveling apparatus in the present invention
Upper pressure wheel is fixed on fixed frame, and is moved up and down by hydraulic system driving fixed frame, to be driven on upper pressure wheel by fixed frame
Lower movement, finally realizes and the gap between upper pressure wheel and lower pressure wheel is adjusted, and then adapts to various sizes of band steel band
Smoothing operation.
Detailed description of the invention:
