Abstract
The invention relates to a roller surface quality examination method, and specially, relates to a light examination method of roller surface grinding quality. The light examination method of roller surface grinding quality comprises that after roller grinding, through an examination person, lights form a flashlight is radiated on a roller surface along a direction which forms an included angle of 30 degrees with a roller axial direction, and through flashlight shaking, irradiation positions or angles can be changed, wherein through reflected lights, a roller surface state is shown and defects can be determined. Through the light examination method of roller surface grinding quality, roller surface defects can be clearly examined. The light examination method of roller surface grinding quality is simple and convenient and does not produce adverse influences on roller surfaces.
Description
Technical field
The present invention relates to the roller surface quality inspection method, relate in particular to the inspection method of roller surface grinding quality.
Background technology
Flat cold-rolled sheet the most important thing is plate surface quality, and the height of the class of plate surface quality depends on the surface quality of the used roll of milling train.SS-CRM milling train and TCM unit are the core production lines of cold rolling mill; The height of the product surface quality level of this unit production directly has influence on cold-rolled products quality level; So cold rolling mill is quite paid attention to the process unit's ability and the quality level of the used roll of this unit, thereby the grinding surface quality of breaker roll has also proposed quite high quality requirements.
In order to guarantee the roller surface quality for cold rolling processing, grinding roller just must all will carry out conscientious scrutiny to each roller surface quality situation of institute's grinding.Thereby the efficient of the inspection that how to improve the quality has just become the problem of grinding roller considered.The cold roll grinding surface quality of high-quality surface requirement at present mainly checks emery wheel to walk defectives such as tool marks and oscillation mark by chalk; This method needs the supervisory personnel to hand chalk; Chalk by at roller surface, is let roll rotation simultaneously, check through the lines that chalk draws; This method operation is not easily, and has the hidden danger that scratches roller surface because of the impurity in the chalk.
Summary of the invention
The present invention is intended to address the above problem, and a kind of roller surface grinding quality optical test method is provided.The present invention can clearly be checked through the defective of roller surface, and is simple and convenient, can not have a negative impact on the breaker roll surface.
A kind of roller surface grinding quality optical test method; It comprises; After accomplishing roll dressing, the supervisory personnel utilizes a torch, from shining roll farming face with the angle direction of roll axis 10-30 degree; And rock torch change irradiation position or angle, can know according to reflected light and see the roller surface situation and judge defective.
Described roller surface grinding quality optical test method, said can know according to reflected light see the roller surface situation and judge that defective comprises: the grinding line is normal till evenly; Obviously there is the banded zebra-stripe shape of wide cut decorative pattern to explain that then roll surface has abrasive grinding wheel to walk the tool marks defective if having along circumference; If have obvious along there being the wide cut roe figure to explain that then roll surface has grinding vibration mark defective on the axis direction.
Described roller surface grinding quality optical test method, said torch is the cold light torch.
As long as the present invention adopts the torch setting sun can clearly to be checked through if the surface exists emery wheel to walk defectives such as tool marks and oscillation mark for the operative employee is equipped with strong cold light electric torch after roll dressing is accomplished, and prevents the generation of secondary defect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Fig. 1 is a synoptic diagram of the present invention.
Embodiment
The purpose of roll dressing mainly provides polishing, a dimensional accuracy grinding skin higher, that meet rolling requirement once more for milling train.But in actual production, usually can occur because the variation of grinding process condition produces following defective:
Roller surface grinding oscillation mark;
The roller surface emery wheel is walked tool marks;
Roller surface sand grains cut;
The hacking aberration;
Hacking water pelmatogram.
Therefore how to find roller surface grinding defective quickly and efficiently, do not allow a defective to residue in roller surface, flat cold-rolled sheet is produced high-quality steel plate have important and practical meanings.
See also Fig. 1, as shown in the figure, a kind of roller surface grinding quality of the present invention optical test method; It comprises; After accomplishing roll 2 grindings, the supervisory personnel utilizes a torch 1, from shining roller surface with the angle direction of roll axis 10-30 degree; And rock torch 1 change irradiation position or angle, can know according to reflected light and see roll 2 surface conditions and judge defective.Said torch is the cold light torch.
Described roller surface grinding quality optical test method, said can know according to reflected light see the roller surface situation and judge that defective comprises: the grinding line is evenly for normal; Obviously there is the banded zebra-stripe shape of wide cut decorative pattern to explain that then roll surface has abrasive grinding wheel to walk the tool marks defective if having along circumference; If have obvious along there being the wide cut roe figure to explain that then roll surface has grinding vibration mark defective on the axis direction.
Claims (3)
1. roller surface grinding quality optical test method; It is characterized in that it comprises, after accomplishing roll dressing; The supervisory personnel utilizes a torch; From with the angle direction of roll axis 10-30 degree irradiation roller surface, and rock torch and change irradiation position or angle, can know according to reflected light and see the roller surface situation and judge defective.
2. roller surface grinding quality optical test method according to claim 1 is characterized in that, said can know according to reflected light see the roller surface situation and judge that defective comprises: the grinding line is evenly for normal; Obviously there is the banded zebra-stripe shape of wide cut decorative pattern to explain that then roll surface has abrasive grinding wheel to walk the tool marks defective if having along circumference; If have obvious along there being the wide cut roe figure to explain that then roll surface has grinding vibration mark defective on the axis direction.
3. roller surface grinding quality optical test method according to claim 1 is characterized in that said torch is the cold light torch.
