Abstract
The invention provides a kind of intermediate blank lateral bending detection method, make by anterior light projector section and rear handle light projector cylinder, light projector section side is equidistantly provided with 5 light projector holes, and light projector section is built with the illuminator of blue-light source, and handle is built with electrical storage device.During detection, make the blue ray penetrated in 5 light projector holes be incident upon in the intermediate blank of high temperature, by blue luminous point in intermediate blank distribution transversely, detect the extent of deviation of intermediate blank center line.Mobile light projector cylinder, makes blue luminous point transverse shifting in the intermediate blank of motion, measures the longitudinal lateral bending degree of intermediate blank by the movement locus of blue luminous point.The present invention effectively can detect the lateral bending degree of intermediate blank, realize the diagnosis to intermediate blank lateral bending situation and anticipation, and carry out pre-adjustment in finish rolling accordingly, thus prevent from crossing process, clash into the steel-fastening accident that side jig causes, reduce processing time and loss due to spoiled work, ensure carrying out smoothly of production.
Description
Technical field
The invention belongs to separate-blas estimation field, particularly relate to a kind of detection method for lateral bending of hot-rolled intermediate billet degree.
Background technology
The function of roughing mill in hot rolling plays to carry out cogging, rough machined effect to slab, and provide intermediate blank raw material to finish rolling.But, there is the various abnormal causes such as transverse temperature inequality and wedge shape due to intermediate blank, intermediate blank head is caused to produce lateral bending phenomenon, progressively can accumulate in finishing stands when lateral bending is serious, increase the weight of the degree of lateral bending, thus impinge upon in crossing process on the jig of side and cause steel-fastening accident, not only increase loss due to spoiled work, and have a strong impact on carrying out smoothly of production.
Summary of the invention
The present invention aims to provide one can carry out initial survey and anticipation to intermediate blank lateral bending situation, thus avoids steel-fastening accident, reduces the intermediate blank lateral bending detection method of causality loss.
For this reason, the solution that the present invention takes is:
A kind of intermediate blank lateral bending detection method, it is characterized in that, concrete grammar and step are:
1, light projector cylinder is made:
Cylindrical shape light projector cylinder is made up of anterior light projector section and rear handle; Light projector section side is equidistantly provided with the light projector hole that 5 diameters are ￠ 1.8-2.2mm, and light projector section nose threads is connected with end cap, and light projector section is built with the illuminator of blue-light source; Handle, built with electrical storage device, is provided with power switch outside handle.
When 2, detecting, hand-held light projector cylinder, opens the power switch on handle, makes the blue ray penetrated in 5 light projector holes be incident upon in the intermediate blank of high temperature, clearly shows 5 blue luminous points equidistantly distributed on the intermediate blank surface of redness.
3, by symmetrical blue luminous point in intermediate blank distribution transversely, visually detect the extent of deviation of intermediate blank center line.
4, mobile light projector cylinder, blue luminous point is vertically moved in the intermediate blank of motion, when the detection luminous point vertically moved has one end to move outside intermediate blank, and intermediate blank generation lateral bending is described when the other end moves to the inside, measures the longitudinal lateral bending degree of intermediate blank by the movement locus of blue luminous point; If detect sideslip result when macroscopic more than 5mm, finishing mill operator carries out deviation adjusting in follow-up rolling.
Described light projector cylinder diameter is 45-55mm, and length is 250-280mm.
Described light projector cylinder circular hole spacing is 7-10mm.
Described illuminator is bulb.
Beneficial effect of the present invention is:
The present invention effectively can detect the lateral bending degree of intermediate blank, realize the diagnosis to intermediate blank lateral bending situation and anticipation, and carry out pre-adjustment in finish rolling accordingly, thus prevent from crossing process, clash into the steel-fastening accident that side jig causes, reduce processing time and loss due to spoiled work, ensure carrying out smoothly of production.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The concrete steps of intermediate blank lateral bending detection method of the present invention are:
1, light projector cylinder is made:
Light projector cylinder is a cylindrical shape, and diameter is 50mm, overall length 250mm, is be made up of anterior light projector section 3 and rear handle 5, and wherein light projector section 3 length is 150mm.
Equidistantly be provided with the light projector hole 2 that 5 diameters are ￠ 2mm in the side of light projector section 3, adjacent two light projector hole 2 spacing are 8mm.The front end of light projector section 3 has been threaded connection end cap 1, and the bulb of blue light is equipped with in the inside of light projector section 3.In handle 5, be equiped with electrical storage device, the outside of handle 5 is provided with power switch 4.
When 2, detecting, hand-held light projector cylinder, opens the power switch 4 on handle 5, makes the blue ray of injection in 5 light projector holes 2 be incident upon in the intermediate blank 6 of high temperature, clearly shows 5 blue luminous points equidistantly distributed on intermediate blank 6 surface of redness.
3, by symmetrical blue luminous point in intermediate blank 6 distribution transversely, the extent of deviation of intermediate blank 6 center line can be visually detected.
4, mobile light projector cylinder, make blue luminous point transverse shifting in the intermediate blank 6 of motion, when the detection luminous point vertically moved has one end to move outside intermediate blank 6, and the other end illustrates that lateral bending occurs intermediate blank 6, measures longitudinal lateral bending degree of intermediate blank 6 by the movement locus of blue luminous point when moving to the inside; If detect sideslip result when macroscopic more than 5mm, finishing mill operator carries out deviation adjusting in follow-up rolling.
