Description
Technical field
The utility model relates to a kind of pick-up unit, specifically, the utility model relates to a kind of coil of strip limit and splits depth detection apparatus, and described coil of strip limit is split depth detection apparatus and is used in coil of strip (band steel) production run to metallurgical engineering recurrent limit and splits defective and detect.
Background technology
In coil of strip (band steel) the hot-rolled and cold-rolled production run of metallurgical industry system, defective (or claiming the limit to split) is split on the limit that occurs in the marginal portion generation of coil of strip (band steel) through regular meeting.Adopt macrostructure test, chemical composition analysis and metallographic testing methods, the band coil of strip that occurs splitting on the limit has been carried out dissection and analysis, the result shows, the latent defect of steel billet, heating-up temperature is higher and heat inhomogeneous is to produce the main cause that the limit is split.
For example, in the operation of rolling of cut deal, the temperature of steel plate limit portion is reduced in red crisp district scope, the performance of metal is in between plasticity and the high sensitive data that ruptures in this district, so when continuation is rolling, the transversal crack of discontinuity appears in the relatively poor limit portion of extensibility, causes recovery rate to descend significantly.Particularly, in the hot continuous rolling of stainless-steel rolls such as hot rolling austenite, martensite, ferrite etc. was produced, the breach defective of different depth appearred in two limit portions of roll bending.The raw edges degree of depth is serious reaches 5mm～15mm.This not only requires cold rolling preceding must the side cut, has increased the side cut loss of cold rolling process, and cold-rolling stainless steel factory production cost is increased, in case and breach is cut unclean, breach just has the possibility of expansion and broken belt when cold rolling, and therefore, the hot rolling limit is split becomes a comparatively serious problem.
In addition, mild carbon steel twists in the cross break that produces in uncoiling, the aligning process and also may cause the limit to split defective.
By relevant regulations, the limit of rolling hard volume splits or toothed edge should be not more than 2mm, and the limit in 50 meters of the inner cores splits or toothed edge should be not more than 3mm.Roll hard volume because the excision band defect part of having no chance therefore allow the delivery of band defective, but defective part must not surpass 6% of every volume total length.
Though, according to steel plate thickness, yield strength the smoothing roll roll gap is set rationally, improve uncoiling aligning speed, smoothly can improve straightening quality, or in Rolling Production the approach of compensation plastic deformation, can partly solve the problem that Medium and Heavy Plate Rolling Production process limit is split; Or improve the last three passage operation of rolling strip edge edge temperature of hot-strip and improve upright groove arrangement position, can eliminate severe edge fracture; Or the adjustment molten steel composition, the control sheet billet splits to eliminate or to alleviate the limit at the turnover temperature and time of soaking pit.But defective (or claiming the limit to split) is split in case produce in the limit, just must excision.Particularly whether cold-rolled products can split excision with the limit in order to determine the back operation, just must understand the degree of depth that the coil of strip limit is split, thereby determine that clearance, the machine excision of going up still are directly to demote, so must accurately detect the degree of depth that the coil of strip limit is split.Do not detect and there is effective testing tool that the degree of depth is split on the coil of strip limit at present, can only wait for that substantially coil of strip launches after, could understand the limit and split the degree of depth, to let pass, to go up the machine excision or directly to demote.Inefficiency.
In view of above-mentioned, the purpose of this utility model is, provide a kind of coil of strip limit to split depth detection apparatus, described coil of strip limit is split depth detection apparatus and is used in coil of strip (band steel) production run to metallurgical engineering recurrent limit and splits defective and detect, depth detection apparatus is split on coil of strip of the present utility model limit can be under the state of band steel rolling, coil of strip (band steel) is carried out convenience, depth detection is split on the limit accurately, take this, can directly obtain the measured data that the degree of depth is split on the coil of strip limit, determine whether this coil of strip can directly let pass, last machine excision is still directly demoted, thereby avoid the limit to split the excessive coil of strip of the degree of depth and flow to down operation, prevent processing and logistics that it influences next procedure, improve coil of strip production efficiency.
