Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Shown in 1~Fig. 2 of reference picture, a kind of new ladle with early warning described in the utility model, including ladle
Permanent layer 2 and working lining are sequentially provided with shell 1, ladle shell 1, ladle shell 1 is provided with multiple exhaust outlets, in addition to early warning
Circuit, early warning circuit includes power supply 7, early-warning lamp 6, multiple positive wires 4 and multiple cathode conductors 5, and positive wire 4 and negative pole are led
Exhaust outlet of the one end of line 5 respectively outside ladle shell 1 is penetrated, and is distributed between permanent layer 2 and working lining, the He of positive wire 4
Cathode conductor 5 is not connected mutually, and the positive pole that the other end of multiple positive wires 4 converges afterwards with power supply 7 is connected, multiple cathode conductors
5 other end is connected after converging by early-warning lamp 6 with the negative pole of power supply 7；When working lining is eaten away by molten steel, steel contacts to positive pole
Wire 4 and cathode conductor 5, turn on early warning circuit, and early-warning lamp 6 is bright, realize the early warning to steel ladle working layer bleed-out, can
Accurately and quickly check whether working lining also has thickness, effectively reduce equipment fault and downtime, instead of visual inspection and
It is unfavorable that artificial experience judges, reduces worker's labor intensity, is that our factory produces direct motion there is provided sound assurance, will also produce
Preferable social benefit.
Further, the multiple 5 points of positive wire 4 and multiple cathode conductors is multiple wire groups, each wire group bag
1 positive wire 4 and 1 cathode conductor 5 are included, each wire group is penetrated from the exhaust outlet on ladle shell 1.
Further, the number of positive wire 4 and cathode conductor 5 is 4~15.
Further, the thickness of permanent layer 2 is 60mm, and the length of positive wire 4 and cathode conductor 5 is 70mm.
Further, the positive wire 4 and the end face of the one end of cathode conductor 5 that are distributed between permanent layer 2 and working lining with
Permanent layer 2 is parallel.
In one embodiment of the present utility model, operation principle of the present utility model：
The positive and negative polarity wire 5 in permanent ladle layer 2 designed by the utility model, including be embedded in during the knotting of permanent layer 2
In permanent layer 2, it is characterized in that：Described wire one end is penetrated from tank box hat exhaust outlet is beaten, end face and the permanent layer 2 of wire
It is parallel, using molten steel conductivity principle, the pre-buried positive and negative polarity wire 5 between permanent ladle layer 2 and working lining, when operational layer brick is by steel
During water enchroachment (invasion) eating away, steel contacts are to the positive and negative polarity wire 5 of permanent layer 2, and alarm lamp is bright.
After early warning circuit, it is that 0mm continues to heat molten steel to have prevented ladle in the residual thickness of working lining, causes ladle leakage
Steel adds safety factor in the generation of our factory equal on the basis of operating personnel's experiential operating；Worker's labor intensity is reduced,
Direct motion is produced there is provided sound assurance for our factory, will also produce preferable social benefit.
Such as occur ladle slag line position bleed-out accident, casting machine will be caused to stop production 8 hours or so, ladle involucrum is damaged etc..This
It is recommended that implementation, loss can be reduced.
Casting machine production suspension induced losses：
Casting machine produces 8h, pourable 9 stove molten steel：
9 115 tons of stove * (tap)=1035 ton
1035 tons * 1300 yuan/ton (converter ton steel cost)=134.55 ten thousand yuan
Ladle involucrum is damaged：10000 yuan/set
Three add up to, and loss can be reduced altogether：Ten thousand yuan of 134.55+3.2+1=138.75
3rd, benefit is created in the implementation of this suggestion：138.75 ten thousand yuan.
As shown in figure 1, the circular hole that ladle shell 1 is provided with is permanent provided with knotting in ladle steam vent 3, ladle shell 1
Layer 2；Positive wire 4 and cathode conductor 5 are respectively equipped with circular hole, permanent layer 2 is penetrated from same steam vent 3.
As shown in Fig. 2 circle represents early-warning lamp 6 in figure, the positive pole of different steam vents 3 is connected together, negative pole is connected in one
Rise, form parallel circuit；Both positive and negative polarity UNICOM in whichever steam vent 3, early-warning lamp 6 can all be lighted, and play alarm function.
This pre-buried detection instrument is further described in detail with specific embodiment below in conjunction with the accompanying drawings.
1st, before the knotting of permanent ladle layer 2, positive wire 4 and cathode conductor 5 (high temperature resistant) are worn from same steam vent 3
Enter in ladle and reserved 70mm length (permanent ladle layer 2 is 60mm), it is ensured that positive and negative polarity wire 5 can pass through permanent layer 2；
2nd, permanent ladle layer 2 is knotted again, positive and negative polarity wire 5 is fixed；
3rd, another terminals of positive and negative polarity wire 5 and power supply 7 (power supply is battery), early-warning lamp 6 are connected into loop.Reason
Want in the case of pouring, permanent layer 2 should not contact molten steel, and refractory material is not conductor in ladle, the loop of early-warning lamp 6 disconnects, in advance
Warning lamp 6 extinguishes；
4th, when steel ladle working layer has corroded, during steel contacts permanent layer 2, positive and negative polarity wire 5 is exposed in molten steel, early-warning lamp
6 loops are ganged up, and early-warning lamp 6 is bright, play the effect of alarm, it is to avoid the further expansion of accident.
Only preferred embodiment of the present utility model above, can not limit the power of the utility model with this certainly
Sharp scope, therefore the equivalence changes made according to present utility model application the scope of the claims, still belong to protection domain of the present utility model.
