Said rigid posts end electrically connects through lead and ohmmeter.
A kind of blast furnace is the simple measurement method of coke and ore layer thickness distribution radially, and this method is after the blast furnace filler finishes, and before the air-supply, gets into that the furnace roof charge level carries out, and this method is:
(1) radially equidistantly between furnace throat center and furnace wall chooses a plurality of MPs;
(2) choose two and indicate graduated conductive rigid bar respectively as par and thief rod; And this par and thief rod connected with ohmmeter through lead; This par and thief rod are inserted with essentially identical speed in the bed of material at a RP place simultaneously,, show that these two rigid posts all are in coke layer to forming current return; Said RP is distributed between furnace throat center and the furnace wall, and vertical with said MP place furnace throat radius;
(3) the bar invariant position that maintains the standard is extracted thief rod, and inserts in the bed of material of first measurement point until forming the loop once more; Scale is represented first floor ore layer thickness shown at this moment on the thief rod; Continuation is inserted the darker bed of material with thief rod, disappear until the loop, at this moment; The thickness that scale shown on the thief rod deducts first floor ore layer is first floor coke thickness, thief rod is extracted again;
(4) set by step ore layer and coke thickness are measured in the operation of (3) successively on all the other MPs.
Particularly, be to adopt the mode of sledgehammer strike that par and thief rod are inserted the bed of material in this method.
Preferably, said rigid posts comprises the conduction rigid posts body with sharp-pointed front end, and said rigid posts body all is coated with colourless electric tape on the surface except that front end.
The length of said rigid posts is decided according to coke and ore layer mean thickness that batch heavy, the bulk density and the throat diameter of coke and ore calculates;
Said conductor length is decided according to the furnace throat radius;
The range of said ohmmeter is decided according to the resistance of coke and ore.
Compared with prior art; The advantage of the utility model is: this measuring apparatus is simple in structure; Cost is low, and easy and simple to handle, after can making full use of the blast furnace opening filler and finishing; The thickness profile data of production setup time measurement blast furnace central coke layer, ore layer, coke and ore mixolimnion before the air-supply, this is crucial for blast furnace material distribution with air-supply adjustment and mathematical model checking.
Description of drawings
Fig. 1 measures the radially structural representation of the ordinary surveying device of coke and ore layer thickness distribution of blast furnace in the utility model one preferred embodiment;
Fig. 2 is the blast furnace measuring method principle schematic of coke and ore layer thickness distribution radially in the utility model one preferred embodiment.
Embodiment
Be further described below in conjunction with accompanying drawing and a preferred embodiment technical scheme the utility model.
Consult Fig. 1, radially the ordinary surveying device of coke and ore layer thickness distribution is by two rigid posts 11,12 with electroconductibility for this blast furnace, and ohmmeter 2 and the lead 3 that connects two rigid posts are formed.
This rigid posts comprises and has graduated conduction rigid posts body, and all is coated with colourless electric tape 4 on this rigid posts body surface except that front end.
This rigid posts body front end is pointed, in the hammering process, is easy to creep in the bed of material, and this part is exposed not to be coated by colourless electric tape.
Scale begins from rigid posts body front end, and the degree of depth of throwing the bed of material into is the scale data presented.
Other part coats by electric tape except that rigid posts front end sharp shaped material, and electric tape need play the insulating effect, and insulation effect will be got well, and intensity is high, guarantees in the process of beating, not galled by coke or ore layer.
The length of rigid posts is confirmed according to coke and ore layer mean thickness that batch heavy, the bulk density and the throat diameter of coke and ore calculates.The length of lead can be confirmed according to the radius of furnace throat.The range of ohmmeter can be confirmed according to the coke of measuring respectively before the experiment and the resistance of ore.
After this ordinary surveying device blast furnace filler capable of using finishes, blow the time before, carry through big manhole entering furnace roof charge level by manual work and measure.
Consult Fig. 2, the measuring method of using this ordinary surveying device to carry out is following:
1, consults Fig. 2, after the entering stove is interior, be divided into some equal portions to the furnace throat radius, be illustrated as 7 MPs along the furnace throat center to furnace wall.Consider the urgency of blow-on, MP can be controlled according to the time that allows.Do with corresponding mark on each MP.
2, at first confirm a par 11, and par is inserted in the coke layer.Consult Fig. 1, blast furnace completes and expects that the top, back one deck is an ore 5 usually, and the second layer is a coke 6.The resistance of the resistance ratio coke of ore is much bigger, and at coke layer but not ore layer, two rigid posts must form the loop between two rigid posts, coke layer and the ohmmeters simultaneously all at coke layer in order to ensure par.Because as long as a rigid posts is arranged in ore layer, because ore resistance is very big, the loop is in off-state, can't the judgement criteria bar be at coke layer or at ore layer.On the vertical direction certain distance of 7 MPs, two rigid posts are squeezed in the bed of material with identical speed simultaneously, up to forming the loop, ohmmeter shows the resistance of coke.Then thief rod 12 is extracted the thickness measurement of each measurement point coke and ore layer.
3, be example with MP among Fig. 24, it is very big heavily to be beaten the value that shows on the ohmmeter in the process of ore layer at thief rod, touches coke up to the front end MP of thief rod, at this moment forms the loop between coke layer and two Metallic rod, and resistance value descends rapidly.Write down the scale value HO on thief rod this moment, represent the thickness of this measurement point ore layer.Continue to beat the registration of thief rod on ohmmeter and rise rapidly, form open circuit between coke layer and two Metallic rod.Write down the scale value HT on thief rod this moment, then the numerical value of the thickness HC of this measurement point coke layer is the difference of HT and HO.Thief rod is extracted the measurement ore of other each measurement point and the thickness of coke layer successively.
4, after the surveying work of each MP is accomplished, describe the radially curve of coke and ore layer thickness distribution of blast furnace shown in Figure 2 according to measuring numerical value.
Need to prove that in aforementioned measuring method, thief rod gets into the bed of material by sledgehammer strike, in the strike process, need to pay close attention to the variation of thief rod high scale, control the hitting dynamics of weight in view of the above; The registration that also need observe simultaneously ohmmeter changes, and confirms the bed thickness of coke and ore in view of the above.According to same principle, the commercial measurement blast furnace that also can use the utility model is the thickness of coke and ore mixolimnion radially.
Although the embodiment of the utility model is open as above; But for being familiar with those skilled in the art; Can easily realize other modification; Therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
