At present, domestic station boiler water water wall section generally carries out by the way of band steel adds steel pipe docking continuously to weld Welding, application 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 Need that there is certain roughness during material external coating coating, otherwise face coat easily comes off, and causes corrosion.According to sandblasting Band steel surface after processing smoothing, due to the limitation of size, there are the shortcomings of intractability is big, cost is higher, low production efficiency. Meanwhile the gap between existing band steel leveling apparatus upper pressure wheel and lower pressure wheel is not easy to adjust, various sizes of band steel is being smoothed During band, need artificially to adjust manually, it is cumbersome and time consuming, it is unsatisfactory for the requirement efficiently produced.
The content of the invention：
The present invention is to overcome drawbacks described above, there is provided a kind of leveling apparatus of station boiler band steel band and its system of smoothing wheel Make method, its 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 of the band steel band that leveling device is processed；Its second technical problem to be solved is logical Cross set moveable upper pressure wheel, solve smoothed in existing leveling apparatus wheel gap be not easy to adjust technical problem.
The present invention station boiler band steel band leveling apparatus, to achieve the above object used technical solution be： 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 arranged on 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 on 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 the leveling apparatus of the present invention, the technical solution of use is, comprises the following steps：
A, blanking；
B, it is quenched；
C, machine adds；
D, annular knurl；
E, surface high frequency quenches.
As a further improvement on the present invention, the smoothing turbine add-on type is placed in radio-frequency induction coil outside carrying out Surface is heated, sensing heating frequency 100KHZ~200KHZ, 1~2 minute heating time, takes out oil quenchinng to less than 400 DEG C It is fuel-displaced, it is air-cooled to room temperature.
As a further improvement on 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 on the present invention, after step e, will smoothing wheel insulation 1~2 it is small when, take out oil quenchinng extremely Less than 300 DEG C.
As a further improvement on the present invention, smoothing wheel after cooling will be quenched to be placed in chamber type annealing stove, temperature At 570~610 DEG C, insulation 2~3 is taken out air-cooled when small for control.
As a further improvement on the present invention, the case hardness after surface high frequency quenching treatment is controlled in HRC48~55, is quenched Saturating more than depth 2mm.
The beneficial effects of the invention are as follows：The present invention is provided with annular knurl lines on the surface of smoothing wheel, so makes 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, so as to be driven by fixed frame on upper pressure wheel 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.
