Description
Technical field
The present invention relates to smelting iron and steel technical field, particularly a kind of measuring method of coil of strip diameter.
Background technology
The end of the smelting line with steel will carry out reel, thus completes whole production flow process; In process, the diameter of coil of strip is the important indicator weighing coil of strip specification, and therefore monitoring coil of strip diameter in real time becomes important action-item.
The method of traditional real-time calculating coil of strip diameter is according to calculating the number of turns that in coil process, reel rotates, again according to the thickness of band steel, to be multiplied with belt steel thickness by the number of turns and can to draw rolled up band steel gross thickness, the radius of adding reel just can draw the radius of coil of strip external diameter, thus draws the surface diameter of coil of strip external diameter.Cannot gap accurately between control cincture steel but the drawback of the method is, thus greatly reduce the accuracy of measuring and calculating.
Summary of the invention
Technical matters to be solved by this invention is to provide and a kind ofly promotes the method that coil of strip diameter calculates accuracy in real time.
For solving the problems of the technologies described above, the invention provides a kind of measuring method of coil of strip diameter, on output strip line, the diameter of coil of strip is calculated in real time; It is characterized in that, comprise the following steps:
By pinch roll, described band steel is sent into rotary machine, controlling drum diameter is an expansion;
When band steel completes the operation twisting in 1.5 circles on reel, expansion drum diameter is two expansions;
Pass through formula
calculate the diameter of coil of strip;
Wherein, D
0for pinch roll diameter, W
0pinch roll angular velocity, W
1for the angular velocity of reel, D

Further, the roll gap pressure value of described pinch roll is more than or equal to 30KN.
Further, described reel one expands diameter range is 752mm ~ 756mm.
Further, described reel two expands diameter range is 764mm ~ 768mm.
The measuring method of coil of strip diameter provided by the invention is by the coil action of accurate control cincture steel, and tight holddown belt steel, greatly reduces its gap, reduce error effect; Avoid on the other hand directly being obtained by band steel measuring intermediate quantity, cross reel and pinch roll obtains the higher intermediate quantity of accuracy, thus promote the precision of results of measuring further.
Accompanying drawing explanation
The coil operation chart that Fig. 1 provides for the embodiment of the present invention.
Embodiment
See Fig. 1, the measuring method of a kind of coil of strip diameter that the embodiment of the present invention provides, comprises the following steps:
By pinch roll, described band steel is sent into rotary machine, controlling drum diameter is an expansion;
When band steel completes the operation twisting in 1.5 circles on reel, expansion drum diameter is two expansions;
Pass through formula
calculate the diameter of coil of strip;
Wherein, D
0for pinch roll diameter, W
0pinch roll angular velocity, W
1for the angular velocity of reel, D
1for the diameter of coil of strip.
Pinch roll 2, in real-time coil process, is pressed against band steel 1, is moved by rotation friction traction belt steel 1.And when pressure arrives to a certain degree, can not skid between band steel 1 and pinch roll 2, namely friction force between the two belongs to static friction, can not produce relative motion at contact point, be now with steel 1 travelling speed equal with the linear velocity of pinch roll 2.
The motor of pinch roll 2 is connected with pinch roll increment type speed encoder by pinch roll scrambler connecting rod, makes the angular velocity of rotation measuring pinch roll 2 that pinch roll increment type speed encoder can be real-time.According to the angular velocity W that pinch roll increment type speed encoder is measured
0, and the diameter D of known pinch roll 2
0, the linear velocity of bottom pinch roll 2 can be calculated, thus obtain the speed being with steel, also namely obtain the linear velocity of coil of strip outer.
The motor of coiler mandrel 3 is connected with reel incremental encoder by reel scrambler connecting rod, and such reel incremental encoder can measure the angular velocity of rotation W of coiler mandrel in real time
1; Thus when coil of strip outer angular velocity is known, its diameter D can be calculated
1; In visible process, that is not just with steel batches the number of turns, and the intermediate quantities such as thickness are carried out measuring and calculating and quoted, and avoid the measuring and calculating error that reeling quality causes; Thus greatly improve the estimation precision of diameter.
The roll gap pressure value of pinch roll 2 is more than or equal to 30KN; Thus ensure to remain static friction effect between band steel 1 and pinch roll 2, ensure that the speed of band steel 1 is equal with the linear velocity of pinch roll 2 outer, thus ensure the accuracy of two measuring and calculating in the middle of pinch roll 2.
According to the product demand of reality, it is 752mm ~ 756mm that reel one expands diameter range.
Draw in order to avoid causing band steel excessively to stretch at expansion drum diameter, two expansion diameter ranges are 764mm ~ 768mm.
The measuring method of coil of strip diameter provided by the invention is by the coil action of accurate control cincture steel, and tight holddown belt steel, greatly reduces its gap, reduce error effect; Avoid on the other hand directly being obtained by band steel measuring intermediate quantity, cross reel and pinch roll obtains the higher intermediate quantity of accuracy, thus promote the precision of results of measuring further.
It should be noted last that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to example to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
