Technical field
The present invention relates to a kind of processing method, in particular to a kind of converter high hopper material position processing methods to belong to certainly for this
Dynamicization control technology field.
Background technique
Plum steel is gathered around there are two steel mill 5 block converter totally at present, in convertor steelmaking process, need to be added the auxiliary materials such as lime and
Alloy raw material, all auxiliary materials and alloy all pass through belt-conveying by underground stock ground and are added to high hopper.Underground stock ground is to height
Position feed bin charging, needs operative employee that must arrive live manual confirmation position in storehouse material position situation, estimation can be with the weight of feeding, then carries out

Data are provided for automation feeding, operator is reduced to bin-level error in judgement, improves the accuracy of feeding, avoid feeding
Insufficient or feeding excessively causes windrow, promotes labor efficiency.
To achieve the goals above, originally technical scheme is as follows, a kind of steel-making high hopper material position processing method,
It is characterized in that, the treating method comprises following steps:
1) volume calculations of feed bin,
2) virtual density calculates,
3) feed bin weight of material calculates,
4) bin-level alarm settings,
5) material position warning output,
6) material position information is shown,
7) feeding preferentially calculates.
As an improvement of the present invention, the volume calculations of the step 1) feed bin are specific as follows, due to material position highest point
It is the position of feed opening, is not suitable for installation charge level detector, is typically chosen in and is slightly away from feed opening, detect the lower position of material
It sets, avoids vibration when blanking from influencing the accuracy of charge level detector, also avoid damaging charge level detector when windrow, according to
Feed bin is divided into the cube on top and the stage body of lower part by the shape of feed bin.
Feed bin is divided into 6 planes, is A, A0, A1, A2, A3 and A4 plane respectively, A0 plane is that the material position O of setting is flat
Face, A2 plane are the charge level of charge level detector detection, and A4 plane is to set the highest plane of material position,
The length/width of each plane is A/B, A0/B0, A1/B1, A2/B2, A3/B3 and A4/B4 respectively；
The height of A0 plane and A1 plane is H22；
The height of A0 plane and A2 plane is H；
The height of A plane and A4 plane is H11；
The height of A plane and A3 plane is H1；
When being practical application between A0 plane and A4 plane, the range (LC) of detection device calculates weight of material in feed bin
(M) and feeding demand (M_SP)；
As setting value A > 0, B > 0, H1 > 0, H11 > 0, A1 > 0, B1 > 0, H2 > 0, H22 > 0 all meets simultaneously, and system thinks to set
Definite value is correct；It is unsatisfactory for if any one, system thinks that setting value mistake, system issue alarm signal (ALARM_SP)；
Calculate the length and width of A0 plane:
A0=A1+ (A-A1) * H22/H2；B0=B1+ (B-B1) * H22/H2；
Calculate the theoretical total measurement (volume) of stage body:
V0=(H2-H22) * (A*B+SQRT (A*B*A0*B0)+A0*B0)；
Calculate stage body and three-dimensional theoretical total measurement (volume):
V3=H2* (A*B+SQRT (A*B*A1*B1)+A1*B1)/3+A*B*H1；
Calculate actual use instrument range:
LC=H1+H2-H11-H22；
Calculate stage body and three-dimensional theoretical total measurement (volume) in actual use instrument range；

A2=A0+ (A-A1) * H/H2；B2=B0+ (B-B1) * H/H2；
V2=H* (A2*B2+SQRT (A2*B2*A0*B0)+A0*B0)/3；
V1=0；
V=V1+V2=V2；
As (H2-H22) < H≤(H1-H11+H2-H22)；
A2=A；B2=B；
V1=A*B* (H-H2+H22)；
V2=V0；
V=V1+V2=V1+V0.
As an improvement of the present invention, the step 2) virtual density calculates specific as follows,
The weight W of material is equal to the volume V of material multiplied by the density p of material, in practical application, since material is particle
Shape, there are gaps between particle, and the practical the space occupied of the material of identical weight is bigger than theoretical space, the material in feed bin
Density ratio material theoretical density wants small, replaces theoretical density ρ with virtual density ρ ' in calculating, so that the weight of material calculates more
Close to true value.
When belt system is opened, dump car starts to align；
When dump car reaches setting feed bin, system automatically records the material position H in current storehouse, while issuing to belt weigher system
Signal automatically resets accumulating weight；
The correspondence oscillating feeder of local blanking bin starts to vibrate, and starts blanking, and belt weigher system starts to accumulate feeding weight
Amount；
When accumulating weight reaches setting weight, oscillating feeder is automatically stopped vibration, and belt weigher system continues to build up
Expect weight；
When the batch material whole warehouse entry, trolley leaves current storehouse, and system automatically records the material position H' and weighing belt in current storehouse
Accumulating weight W'；
By material position variation (H → H') twice before and after discharging, the volume of system-computed discharging bin changes V'；
Final system calculates material virtual density ρ '=W'/V' of the secondary feeding；
The judgement of virtual density ρ ' accuracy:
If m ρ≤ρ '≤ρ (0 < m < 1), system thinks that virtual density ρ ' is calculated rationally, automatically records the data；Otherwise it is
System thinks that data are wrong, issues alarm (accumulation of material weight is wrong or level of filler material detection is wrong).
System automatically records the feed bin material n times virtual density valid data, is then averaged as the material at this
The virtual density ρ ' of feed bin.
DENSITY is the input point of virtual density ρ ' in computing module.

As an improvement of the present invention, step 4) the bin-level alarm settings are specific as follows,
Bin-level sets the material position of 4 grades altogether, is respectively as follows: low material position alarm AL, the alarm of low material position WL, high charge level report
Alert WH, high high charge level alarm AH, are set by HMI picture；
When N1 is low material position, the furnace number used is also made steel enough；
When N2 is low material position, also enough steel-making uses moral furnace number；
N1 and N2 plays left front " √ " selection, is the selection of MODE；
Low material position alarm AL, low material position alarm WL are set there are two types of mode, are selected by MODE；
It is selected when without " √ ", MODE=O, AL and WL is judged according to material bit value set；
When there is " √ " selection, MODE=1, also enough steel-making is set feed bin using furnace number at present, input point M1 in computing module,
For the every furnace usage amount of steelmaking converter, steel-making L2 system is come from；

2) virtual density calculates；
The weight W of material is equal to the volume V of material multiplied by the density p of material.In practical application, since material is particle
Shape, there are gaps between particle, and the practical the space occupied of the material of identical weight is bigger than theoretical space, the material in feed bin
Density ratio material theoretical density wants small, replaces theoretical density ρ with virtual density ρ ' in calculating, so that the weight of material calculates more
Close to true value.
Circular is as follows:
When belt system is opened, dump car starts to align；
When dump car reaches setting feed bin, system automatically records the material position H in current storehouse, while issuing to belt weigher system
