Description
Technical field
The invention belongs to Metallographic Techniques field, more particularly to a kind of analysis coated sheet surface finishing depth and three-dimensional shaped
The method of looks.Suitable for the thin plate after the metal such as surface is zinc-plated, tin plating again Jing Guo finishing.
Background technology
Finishing process is to produce high-quality zinc coated sheet, ensure the last work crucial together of cold-rolling galvanization Strip final product quality
Sequence, it is for improving product quality, control plate shape, being needed to make Strip have suitable mechanical property and surface shape according to user
State etc. plays an important role.Finishing process can mainly improve galvanized steel surface roughness, flatten zinc flower or improve zinc-plated band
Steel mechanical performance and glacing flatness, eliminate and weaken yield point elongation, prevent stretching or deep draw process from skid wire occur, reduce steel plate table
Planar defect, improves heat zinc coating plate surface quality.Therefore, it is necessary to which the degree, effect to finishing process are accurately understood.
The assessment to finishing process effect is evaluated and tested by the roughness of thin sheet surface after finishing at present, and it is one
Online roughmeter is planted to test.Such a method is relatively rough, simply to the system of one roughness substantially of surface of steel plate
Meter, it is impossible to accurately, be clearly measured to finishing depth and analyze its three-dimensional appearance.Cold rolling coated sheet thickness specification is general
In 1mm or so, than relatively thin, and finishing depth is general in the range of several microns, finishing depth dimensions very little, in the past without clear and definite
Means accurate evaluation is carried out to this small finishing depth.In existing literature research, once by adjusting finishing elongation percentage, light
Whole roll-force improves finishing effect, but is all the setting of the finishing process parameter before finishing, is not to finishing effect after finishing
Assessment, it is impossible to accurately and rapidly understand finishing depth and pattern.
The content of the invention
Present invention aims at a kind of method for providing analysis coated sheet surface finishing depth and three-dimensional appearance, solve
The problem of prior art can not accurately, quickly understand finishing depth and pattern and cause to assess poor accuracy.
A kind of to analyze coated sheet surface finishing depth and the method for three-dimensional appearance, specific steps and parameter are as follows：
1st, sample is chosen：Specimen size be long 5mm≤X≤150mm, wide 5mm≤Y≤150mm, thickness 0.5mm≤D≤
30mm, sample upper and lower surface is smooth, no tilting or inclination etc., and thin plate sample preferred size is 20mm × 20mm × 1mm.
2nd, washed samples：Specimen size is 5mm~50mm, sample is placed in the beaker for containing alcohol, then beaker is put
In ultrasonic wave cleaning；After cleaning 5~10 minutes, dry up standby；Specimen size ＞ 50mm's, tried with the absorbent cotton handle for dipping alcohol
Sample surface wipes are clean, standby.Because specimen stage is larger, it is not required to cut into the conventional metallographic specimen size of very little.
3rd, picture is gathered：Ready sample is observed with Laser Scanning Confocal Microscope, chooses and contains finishing and not simultaneously
The visual field in finishing region, two-dimension picture is gathered in the case where multiplication factor is 200X~500X.Visual field retains without the region of finishing
The original appearance of coating microstructure, the region by finishing shows abrasion and flattens vestige.When gathering multiple less than 200X, it is impossible to differentiate
Finishing and non-finishing region, when multiple is higher than 500X, measurable position is less in visual field.
4th, percentage regulation measurement line：The depth survey line in LEXT OLS softwares, including straight line and curve are opened, is made an uproar
" profile width " buttons, set its parameter to measure the processing of line between 1~50 on sonication, adjustment screen.
5th, finishing depth analysis：With mouse drag measure line, carried out from the picture adopted from top to bottom or from a left side to
Right manual scanning, takes and straight line is measured in scanning while the position for being pressed in finishing and non-finishing stops and proceeds by the depth of pointwise
Degree analysis, can also since scanning direction；Finishing position occurs recessed on experiment curv, is flat without curve at finishing
, will not be recessed；Can all there be microrelief recessed and level position, choose the relatively uniform position that rises and falls as measurement point,
The highest and lowest part of fluctuating can not be selected as measurement point.Measurement straight line is determined after analysis position, and curve is clicked on mouse
Corresponding recessed location and horizontal level, obtain the difference in height of the two, as finishing depth.
6th, 6~20 positions of finishing depth survey, take its average value as the finishing depth on coated sheet surface.
7th, adjustment multiple collection picture：500X~1000X multiplication factor is selected, 3D patterns, adjustment image X, Y, Z is selected
The parameter of aspect, obtains the 3-D view suitable for observation during 38≤X≤50, the 88≤Y≤92, Z=0 or 1 of parameter area position.
Coated sheet is general after finishing, finishing region be mostly it is sunk, it is more smooth without the region of finishing, can
The basic side compared as concave-convex surface after finishing, the depth survey line of this method can show the depth difference of the two.Such as
That fruit needs is more accurate, clearly indicate, it is necessary to which select can be in 200X in suitable visual field and appropriate multiplication factor, this method
Select suitable multiple to be measured in the range of~500X multiplication factor, the depth dimensions in micrometer range can be analyzed, can expire
The need for sufficient finishing depth analysis.It is general when observing three-dimensional surface shape simultaneously to use magnification at high multiple multiple, because thin sheet surface
Less, in micro-scaled range, three-dimensional appearance is clear under high power for waviness itself, and three-dimensional appearance performance is not obvious under low power.
The advantage of the invention is that：
1st, this method can be accurately measured the finishing depth of thin sheet surface certain, and then expands to specimen surface
The finishing depth analysis of multiple spot, can carry out system to the finishing of thin sheet surface and comprehensively evaluate；
2nd, this method can show the thin sheet surface three-dimensional appearance after finishing, and intuitively finishing effect is clearly recognized
Know.The complicated sample preparation work such as grind, polish before need not testing sample, directly specimen surface can be analyzed,
Operating procedure is simple, efficiency high.Planar dimension can only be surveyed and can not carry out the phenomenon of depth survey by effectively changing metallographic field,
There is provided a kind of new method of microstructure quantitative measurment.Accurately, pattern and feature intuitively after reaction finishing, is cold rolling plating
Finishing process after zinc provides authentic data, optimizes finishing process parameter, improves quality.
