Abstract
The utility model relates to an online measuring device for a cutting seam of a continuous casting billet, which comprises a measuring needle, a scale and a handle, wherein the measuring needle is connected with the handle through a fixing bolt, and the scale is sleeved outside the measuring needle and can move; the head part of the measuring probe is a cone, and the diameter of the cone is in transition from 4mm to 20 mm; the scale and the probe body are in transition fit. Compared with the prior art, the beneficial effects of the utility model are that: 1) the method can measure the cutting seam width of the continuous casting billet in real time on line, directly evaluate the conditions of the existence of chamfer, burning loss and the like of the flame cutting gun nozzle, and timely replace the flame cutting gun nozzle which reaches the offline standard so as to reduce the loss of steel and improve the yield of molten steel; 2) simple structure, convenient manufacture and use and accurate measurement. 3) The evaluation period is shortened, and the production time is not occupied.
Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of continuous casting billet cutting and is sewn on line measurement mechanism.
Background technology
Along with the development of steel-making continuous casting technology, reducing consumption, cost-saving to steel industry, improve molten steel recovery rate aspect and proposed requirements at the higher level.While using flame cutting machine cutting continuous casting blank, general cutting is sewn between 8 to 10 millimeters, and individual other even reaches 15 millimeters, because the steel loss that cutting seam causes is very huge.The leading indicator whether evaluation flame cutting torch mouth reaches standard of replacement is exactly the size of cutting seam, conventional evaluation method is that rifle mouth uses after certain hour, strand is not cut off and rolled off the production line, after cooling, cut again the measurement in gap, evaluation cycle is longer, can not monitor in real time rifle mouth duty.
Summary of the invention
The utility model provides one on-line measurement continuous casting billet slot width at any time, to determine that the continuous casting billet cutting whether flame cutting torch mouth reaches standard of replacement is sewn on line measurement mechanism, simple in structure, easy to use, be conducive to iron and steel enterprise energy-saving and cost-reducing, reduce production costs.
In order to achieve the above object, the utility model is realized by the following technical solutions:
Continuous casting billet cutting is sewn on line measurement mechanism, comprises chaining pin, scale and handle, and described chaining pin is connected with handle by set bolt, and it is outside and removable that scale is sleeved on chaining pin.
Described chaining pin head is cone, diameter 4mm-20mm transition.
Described scale and chaining pin body are interference fits.
Compared with prior art, the beneficial effects of the utility model are:
1) can real-time online measuring continuous casting billet cutting slit width degree, directly evaluate fire and cut rifle mouth and have or not the situation such as chamfering, scaling loss, the flame cutting torch mouth that reaches lower line standard is changed in time, reduce steel loss to reach, improve molten steel recovery rate;
2) simple in structure, making, easy to use, measures accurately;
3) shorten evaluation cycle, do not take the production time.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Seeing Fig. 1, is the structural representation that the cutting of the utility model continuous casting billet is sewn on line measurement mechanism, comprises chaining pin 1, scale 2 and handle 3, and described chaining pin 1 is connected with handle 3 by set bolt, and it is outside and removable that scale 2 is sleeved on chaining pin 1.
Described chaining pin 1 head is cone, diameter 4mm-20mm transition.
Described scale 2 is interference fits with chaining pin body.The utility model chaining pin body is preferably cylinder.
Seeing Fig. 2, is the utility model working state schematic representation.Before use, the scale 2 that the cutting of the utility model continuous casting billet is sewn on to line measurement mechanism returns zero-bit (front end face is concordant foremost with chaining pin 1), uses set bolt 4 by firmly fixing to handle 3 and chaining pin body 1 afterbody, handle 3 preseting length as required;
In continuous casting billet 5 cutting process, before continuous casting billet 5 does not cut off, grasp handle 3 of the present utility model by flame cutting machine operating personnel, insert in cutting seam vertical chaining pin 1, the bullet head of chaining pin 1 moves downward until be stuck in cutting seam, and scale 2 moves backward along chaining pin 1 surface simultaneously, after chaining pin 1 puts in place, scale 2 also stops mobile, completes fast continuous casting billet 5 cutting on line seams and measures.
The utility model continuous casting billet cutting seam on-line measurement vertical sliding is cut to seam from continuous casting billet 5, because chaining pin body and scale 2 are interference fits, scale 2 positions keep relatively fixing, with the external diameter of vernier caliper measurement scale 2 end chaining pins 1, are corresponding continuous casting billet 5 cutting slit width degree values.
Claims (3)
1. continuous casting billet cutting is sewn on line measurement mechanism, it is characterized in that, comprise chaining pin, scale and handle, described chaining pin is connected with handle by set bolt, and it is outside and removable that scale is sleeved on chaining pin.
2. continuous casting billet cutting according to claim 1 is sewn on line measurement mechanism, it is characterized in that, described chaining pin head is cone, diameter 4mm-20mm transition.
3. continuous casting billet cutting according to claim 1 is sewn on line measurement mechanism, it is characterized in that, described scale and chaining pin body are interference fits.
