[background technology]
At present, occur that wearing stove leaks the generation of iron (steel) phenomenon for preventing and detecting mandreless spinning, be a global difficult problem, reason is detection difficult, reports to the police in advance more difficult.Traditional test mode is direct-detection insulation against ground on coil, to determine the distance of iron (steel) water in stove and coil, thus judges whether that the risk that stove leaks iron (steel) is worn in existence.The weak point of this detection mode is: there is very large hysteresis quality, when finding that there is the possibility of wearing stove often, has had little time to make a response just to there occurs and has worn stove leakage iron (steel) phenomenon.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and provide a kind of mandreless spinning coil insulation against ground pick-up unit, can accomplish that the warning in advance that stove leaks iron (steel) water accident worn by induction furnace, effectively prevent and wear the generation that stove leaks iron (steel) accident.
Design a kind of mandreless spinning coil insulation against ground pick-up unit for achieving the above object, comprise furnace lining 2, the outside of described furnace lining 2 is provided with coil slurry 3, the outside of described coil slurry 3 is provided with coil 4, molten iron in described induction furnace or molten steel 1 are by furnace bottom grounded probe 6 ground connection, described coil 4 is inner has been evenly arranged Hedgehog type probe 5 near coil slurry 3 side, described Hedgehog type probe 5 protrudes from coil 42-6mm, described coil 4 is by connection insulation against ground somascope 7, molten iron in described induction furnace or molten steel 1, Hedgehog type probe 5, furnace bottom grounded probe 6, insulation against ground somascope 7 forms resistance detection loop, alarm is provided with in described resistance detection loop.
Capacitance group 8, inverter cabinet 9, filter reactor 10, rectifier 11 and transformer 12 is also provided with in described resistance detection loop, described capacitance group 8 is by connection between coil 4 and insulation against ground somascope 7, and described capacitance group 8, inverter cabinet 9, filter reactor 10, rectifier 11 and transformer 12 pass through connection successively.
Described Hedgehog type probe 5 adopts multiple 2-6mm fine copper probe to make, and described Hedgehog type probe 5 uniform welding is on coil 4 inwall, and the other end of described Hedgehog type probe 5 is tied a knot in coil slurry 3.
The utility model compared with the existing technology, novel structure, simply, reasonable in design, by arranging by the molten iron in induction furnace or molten steel, Hedgehog type probe, furnace bottom grounded probe, the resistance detection loop that insulation against ground somascope is formed, wherein, Hedgehog type probe uniform welding is in coil on wall, and protrude from coil 2-6mm, and alarm is provided with in this resistance detection loop, thus the inspection achieved iron (steel) water and coil insulation, and then judge the distance of iron (steel) water and coil, finally can accomplish that the warning in advance that stove leaks iron (steel) water accident worn by induction furnace, effectively prevent and wear the generation that stove leaks iron (steel) accident, in addition, mandreless spinning coil insulation against ground pick-up unit described in the utility model, furnace bottom grounded probe and Hedgehog type probe manufacturing simply, and are easily installed.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial schematic diagram at Hedgehog type probe place in the utility model;
In figure: 1, molten iron or molten steel 2, furnace lining 3, coil slurry 4, coil 5, Hedgehog type probe 6, furnace bottom grounded probe 7, insulation against ground somascope 8, capacitance group 9, inverter cabinet 10, filter reactor 11, rectifier 12, transformer.
[embodiment]
Below in conjunction with accompanying drawing, following further illustrating is done to the utility model:
As shown in drawings, the utility model comprises: furnace lining 2, the outside of furnace lining 2 is provided with coil slurry 3, the outside of coil slurry 3 is provided with coil 4, molten iron in induction furnace or molten steel 1 are by furnace bottom grounded probe 6 ground connection, coil 4 is inner has been evenly arranged Hedgehog type probe 5 near coil slurry 3 side, Hedgehog type probe 5 protrudes from coil 42-6mm, this Hedgehog type probe 5 adopts multiple 2-6mm fine copper probe to make, Hedgehog type probe 5 uniform welding is on coil 4 inwall, the other end of Hedgehog type probe 5 is tied a knot in coil slurry 3, coil 4 is by connection insulation against ground somascope 7, molten iron in induction furnace or molten steel 1, Hedgehog type probe 5, furnace bottom grounded probe 6, insulation against ground somascope 7 forms resistance detection loop, resistance detection is provided with alarm in loop, and be also provided with capacitance group 8, inverter cabinet 9, filter reactor 10, rectifier 11 and transformer 12, capacitance group 8 by connection between coil 4 and insulation against ground somascope 7, capacitance group 8, inverter cabinet 9, filter reactor 10, rectifier 11 and transformer 12 pass through connection successively.
Ground connection in the utility model cooperation electrically checks that element realizes the inspection to molten iron or molten steel and coil insulation, and then judges the distance of iron (steel) water and coil.Because the iron of melting in mandreless spinning (steel) water is ground connection, and Hedgehog type probe is that portion is evenly arranged detector probe in coil, probe is utilized to protrude from the design feature of coil 2-6mm, thus by the insulation situation between probe and iron (steel) water, clearly judge the distance of molten iron and coil, can accomplish like this to report to the police in advance, effectively prevent from wearing the generation that stove leaks iron (steel) accident.This Hedgehog type probe is by the fine copper probe uniform welding of 2-6mm in coil wall, but when edge process left no room for manoeuvre by coil, insullac can not be sprayed on detecting probe surface, ensure that the electric conductivity of probe is in shape, then probe be tied a knot in coil slurry.
Each hardware unit that the utility model mainly comprises iron (steel) water, furnace lining, coil slurry, coil, Hedgehog type probe, furnace bottom grounded probe, insulation against ground somascope and is connected with PLC connection.Its concrete principle of work can be checked through the resistance by the loop be made up of molten iron or molten steel, Hedgehog type probe, furnace bottom grounded probe, insulation against ground somascope for: insulation against ground somascope in good time; When molten iron or molten steel because furnace lining is thinning or occur that crack can move closer to coil slurry due to other reasons because iron (steel) water washes away, if molten iron distance coil slurry distance diminishes, and the Hedgehog type probe be fixed on coil protrudes from coil 2-6mm, thus the resistance that earth tester is now checked through can diminish gradually; When resistance R is between 1.5 kilo-ohms and 0.7 kilo-ohm, system can provide warning, and warning is existing runout risk now; When resistance R is less than 0.7 kilo-ohm, power supply there will be forces tripping operation, indicates now abnormally dangerous.Therefore, this pick-up unit described in the utility model has possessed the function given warning in advance.
The utility model is not by the restriction of above-mentioned embodiment; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
