Abstract

The utility model relates to a hot-metal pouring abnormality error correction device for a torpedo ladle car, which comprises a torpedo ladle tilting program controller (PLC) and a human-computer interface thereof which are connected electrically, a contactor, a tilting motor and a temperature sensing cable, wherein the temperature sensing cable is arranged on the side close to a hot metal ladle trolley; the length of the temperature sensing cable is in the range of the length covering the whole hot metal ladle trolley; and an input terminal of the torpedo ladle tilting program controller is connected into the output end of the temperature sensing cable. The hot-metal pouring abnormality error correction device for the torpedo ladle car of the utility model is a device capable of carrying out real-time detection and automatic error correction on hot-metal pouring abnormality, has the advantages of simple structure, reliable detection and timely error correction and effectively avoids equipment damage caused by hot-metal pouring abnormality.

Description

Torpedo tank car is converted the unusual error correction device of iron

Technical field

The utility model relates to a kind of monitoring and error correction device, and specifically, relate to and a kind ofly be applied to torpedo tank car, torpedo tank car is converted iron to hot-metal bottle monitor in real time, and at incline the unusually device of timely error correction when of molten iron.

Background technology

Torpedo tank car is mainly used in molten iron with blast furnace process and is transported to steel-making and is subjected to the iron unit, by converting ironworker's preface molten iron is transferred in the hot-metal bottle by torpedo tank car.Referring to Fig. 1, its technological process of converting iron is as follows: the torpedo jar 10 that fills with molten iron is arrived through dedicated track 30 by torpedo tank car 20 and is subjected to the iron position, when the scale of torpedo tank car overlaps with the scale that is subjected to iron hole track, the torpedo tank car locking, power connection equipment action automatically, the torpedo jar that manually fascinates is fixed behind correct position, convert iron, flow to ladle 40, along with the reduction of torpedo tank level, the angle that artificial fine setting is fascinated is converted iron until finishing.

In converting the process of iron, on the one hand, when the jar mouthful accumulated slag of torpedo tank car is serious, can in converting the iron process, molten iron be shunted; On the other hand, since when converting iron operating personnel from torpedo tank car (about ten meters high-altitudes) far away, because work under bad environment, to the full frame individual's sensation of assurance and the experience of the turning angle of torpedo jar, when having the inclination angle excessive unavoidably.Both of these case all might cause molten iron to flow to zero rice platform 50, with other facilities that flow to behind the platform burn through in ladle chassis 60 bodies and the melt pit, bring out fire, light then cause local devices scaling loss, heavy then cause cable, large-area damage such as the pipeline that can be situated between and jumping, cause the stopping production in converter zone, produce to enterprise and bring serious economy loss.But in the prior art, do not have effective means inclining unusually of molten iron to carry out real-time detection and effectively correction.

Summary of the invention

The purpose of this utility model is to design a kind of torpedo tank car and converts the unusual error correction device of iron, can be to converting that iron detects unusually in real time and the automatic device of error correction, have simple in structure, detect reliable, error correction advantage timely, effectively stopped because of converting the unusual device damage that causes of iron.

For achieving the above object, the technical solution of the utility model is:

Torpedo tank car is converted the unusual error correction device of iron, the torpedo jar that comprises electric connection fascinate cyclelog (PLC) and man-machine interface (HMI), contactor and the motor that fascinates, it is characterized in that, also comprise, temperature sensing cable, be arranged at the side near the ladle chassis, length covers whole ladle chassis length range; The output of temperature sensing cable inserts the fascinate input terminal of cyclelog of torpedo jar.

Further, described temperature sensing cable is installed on the I-steel near a side of ladle chassis.

Described torpedo jar fascinates and is connected by grid line between cyclelog and the man-machine interface; The torpedo jar fascinate cyclelog, contactor, fascinating connects by power cable between the motor.

Temperature sensing cable inside is two elastic wires, every steel wire outside is surrounded by the material of one deck temperature-sensitive and insulation, and under the normal monitoring state, two steel wires are in state of insulation, when the surrounding enviroment temperature rises to the predetermined action temperature, temperature-sensitive material breaks, and two steel wires produce short circuits, input node signal to the torpedo jar cyclelog (PLC) that fascinates, after PLC receives signal, on the one hand, send and convert the unusual alarm signal of iron to man-machine interface (HMI, Human Machine Interface); On the other hand, send forced signal to contactor, control motor auto-reverse, thereby prevent molten iron further incline to, stop the generation of fire.

The beneficial effects of the utility model

The utility model is converted iron abnormality detection accuracy rate 100% by the utilization temperature sensing cable, and by automatic error correction function, has effectively avoided the expansion of accident, has stopped the generation of faults such as fire.

Fig. 2 is the structural representation of the utility model one embodiment;

Fig. 3 is the utility model control principle figure;

Fig. 4 is the utility model user mode schematic diagram.

The specific embodiment

Referring to Fig. 1～Fig. 4, the utility model torpedo tank car is converted the unusual error correction device of iron, the torpedo jar that comprises electric connection fascinate cyclelog 1 and man-machine interface 2 (HMI), contactor 3 and the motor 4 that fascinates; Temperature sensing cable 5 is arranged at the side near ladle chassis 60, and length covers whole ladle chassis 60 length ranges; The output of temperature sensing cable 5 inserts the fascinate input terminal of cyclelog 1 of torpedo jar.

In the present embodiment, described temperature sensing cable 5 is installed on the I-steel 7 near a side of ladle chassis 60.

When converting iron when unusual, high temperature liquid iron acts directly on the temperature sensing cable 5, the signal input torpedo jar cyclelog 1 that fascinates is sent in the steel wire short circuit of temperature sensing cable 5 inside, and the torpedo jar fascinates after cyclelog 1 receives signal, on the one hand, send alarm signal to man-machine interface 2 (HMI), remind operating personnel to check affirmation, send simultaneously and force reverse signal to give contactor, the motor that fascinates is auto-reverse to treating the seat in the plane, to prevent continuing to incline and of molten iron.

Temperature sensing cable 5 85 degree and 105 that have commonly used are spent two kinds of specifications, consider that operating ambient temperature is higher herein, and present embodiment is selected the specifications of 105 degree for use.
