The slab length detecting device provided by the utility model is simple in structure and easy to install. The slab length detecting device can distinguish lengths of detected slabs effectively. And at the same time, the slab length detecting device complements a traditional length detecting method, thereby avoiding accidents and guaranteeing the smoothness of production.
Description
Technical field
The utility model relates to the steel rolling production-line equipment technical field, specifically is a kind of slab device for detecting length.
Background technology
The long function of slab survey commonly used mainly is to measure roller table speed V through the roller-way scrambler to combine roller-way slab tracking grating to detect the time T that slab passes through before the heating furnace at present; These two variablees are multiplied each other draw the slab length L; Though slab is at the uniform velocity through the speed of this group roller-way through the frequency conversion closed-loop control; But be not complete desirable straight slab through slab; Often thereby some slab satisfies the amount of deflection index but exists necessarily perpendicular to roller-way supporting plane crooked up or down and causes slab in the process of transportation, on roller-way, to skid or because minority roller-way overload causes stall; When not working on setting speed, the roller-way of speed measuring coder will cause slab to survey long being forbidden if be equipped with; Influencing slab checks; If run into the long base that exceeds allowed band might the stokehold location is unsuccessful and revoke and influence rhythm of production and output automatically, even more serious is if ultrashort base installs in the stove probably owing to slab is crossed short hundredweight and dropped to less than two fixed beams and cause more unmanageable device damage and blowing out accident in the stove.Slab is surveyed the inaccurate very unfavorable to producing of length.
Summary of the invention
The purpose of the utility model provides a kind ofly can effectively distinguish overlength base and ultrashort base, thereby avoids accident to take place, and guarantees to produce slab device for detecting length smoothly.
A kind of slab device for detecting length according to the utility model provides comprises:
Two overlength base detection components and two ultrashort base detection components;
Two said overlength base detection components and two said ultrashort base detection components are arranged on the same plane that is parallel to the same end face of roller-way, and two said ultrashort base detection components are arranged between two said overlength base detection components.
Further, said overlength base detection components is that the overlength base detects grating, and said ultrashort base detection components is that ultrashort base detects grating.
Further, said overlength base detection components is an overlength base cold metal detector, and said ultrashort base detection components is ultrashort base cold metal detector.
Further, said overlength base detection components is an overlength base hot metal detector, and said ultrashort base detection components is ultrashort base hot metal detector.
Further, be spaced apart 11m between two groups of said overlength base detection components, deviation is smaller or equal to 10mm.
Further, be spaced apart 4.5m between two groups of said ultrashort base detection components, deviation is smaller or equal to 10mm.
Further, the detection port of said overlength base detection components and said ultrashort base detection components is aimed near the center line in said roller-way gap.
A kind of slab device for detecting length that the utility model provides, simple in structure, be prone to install, and can effectively distinguish tested slab length, also tradition is surveyed rectangular method simultaneously and replenish, thereby avoid accident to take place, guarantee to produce smoothly.
Description of drawings
The structural representation of the slab device for detecting length that Fig. 1 provides for the utility model embodiment.
Embodiment
In order to make the purpose of the utility model, it is more clear that technical scheme and advantage are described, and explains below in conjunction with concrete embodiment and accompanying drawing.
Of Fig. 1, the slab device for detecting length that the utility model provides comprises: two overlength base detection components 1 and two ultrashort base detection components 2.Overlength base detection components 1 shown in the present embodiment is that the overlength base detects grating, and ultrashort base detection components 2 is that ultrashort base detects grating.Two overlength base detection gratings and two ultrashort bases detect gratings and are arranged on the same plane that is parallel to roller-way 3 same end face 200mm places; And whether the detection port that the overlength base detects grating and ultrashort base detection grating should be positioned near the center line in roller-way 3 gaps, exist thereby guarantee accurately to detect slab.Two ultrashort bases detect grating and are arranged between two overlength bases detection gratings.Two groups of overlength bases detect between the grating and are spaced apart 11m, and deviation is smaller or equal to 10mm.Two groups of ultrashort bases detect between the grating and are spaced apart 4.5m, and deviation is smaller or equal to 10mm.
When using the described slab device for detecting length of Fig. 1 that slab length is detected; All detection port that detect gratings are aimed between the roller-way 3 in the gap; Shelter can not be arranged, thereby guarantee that radiative point of irradiation guarantees accurately to detect slab and whether exists near roller-way end face roller-way 3 gap center lines.When slab through this group during roller-way 3, slab through or static process in as long as detecting two overlength bases detection gratings of long base has the steel signal to carve simultaneously at a time to exist, that explains this slab overlength.If two ultrashort bases that detect short base detect gratings do not have the steel signal and carve simultaneously at a time and existed, that this slab of explanation is ultrashort.Have or not the steel signal to judge then through the control system collection, thereby let us just can reach the accident that the purpose of distinguishing overlength base and ultrashort base avoids overlength or ultrashort base to cause like this.
A kind of slab device for detecting length that the utility model provides, simple in structure, be prone to install, and can effectively distinguish tested slab length, also tradition is surveyed rectangular method simultaneously and replenish, thereby avoid accident to take place, guarantee to produce smoothly.
Embodiment two:
The difference of present embodiment and embodiment one is that overlength base detection components 1 is an overlength base cold metal detector, and ultrashort base detection components 2 is ultrashort base cold metal detectors.Two overlength base cold metal detectors and two ultrashort base cold metal detectors are arranged on the same plane that is parallel to roller-way 3 same end face 100mm places.Other are local in full accord with embodiment one.
Embodiment three:
The difference of present embodiment and embodiment one is that overlength base detection components 1 is an overlength base hot metal detector, and ultrashort base detection components 2 is ultrashort base hot metal detectors.Two overlength base hot metal detectors and two ultrashort base hot metal detectors are arranged on the same plane that is parallel to roller-way 3 same end face 300mm places.Other are local in full accord with embodiment one.
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
