Abstract
The invention discloses a steel ladle structure capable of quickly giving an alarm when molten steel leaks. The steel ladle structure comprises a fireproof material layer, a steel deck is arranged outside the fireproof material layer, the surface of the steel deck is coated with a first heat insulation coating layer, a combustible material layer is arranged outside the first heat insulation coating layer, and the surface of the outer side of the combustible material layer is coated with a second heat insulation coating layer. Compared with the prior art, the first heat insulation coating layer, the combustible material layer and the second heat insulation coating layer are added to the structure of an original steel ladle, when the molten steel erodes and punctures the whole steel ladle, the molten steel can make combustible materials in the combustible material layer be combusted, a large amount of smoke can be released when the combustible materials are combusted, an aerial crane worker can immediately know that the steel ladle leaks when seeing a large amount of smoke in the steel ladle transfer process, after the aerial crane worker presses an alarm, workshop staff can immediately know that accidents happen and quickly leave a site of accidents, and therefore personal casualty accidents are effectively avoided.
Description
Technical field
While the present invention relates to a kind of molten steel leakage, the steel ladle structure of Rapid Alarm, belongs to steel-making equipment technical field.
Background technology
After molten steel is good, transport through steel ladle.The steel ladle using is now all to use steel plate to make tubbiness, then builds in the steel plate layer the inside of barrel-like structure the refractory masses that has refractory material to be made.But existing often appearance at present damages and cause the accident that molten steel leaks to occur because of steel ladle, and the accident that molten steel leakage occurs is generally mainly 2 kinds of situations, a kind flows out for whole steel ladle tilts to cause the molten steel in steel ladle; Another uses for a long time for steel ladle, and molten steel constantly carries out ablation to steel ladle constituent material, causes molten steel to flow out thereby finally puncture whole steel ladle.Above 2 kinds of situations are burst accident, easily cause a large amount of casualties.For the first accident in use procedure at ordinary times to steel ladle and auxiliary device running check thereof, can greatly avoid the generation of accident.But for the second accident, because first molten steel is to flow out from tiny gap, general staff is difficult to find this gap in the process that checks steel ladle.While causing steel ladle to occur to leak in the time of transhipment molten steel, staff is difficult to the generation of discovery accident.
Summary of the invention
The object of the invention is to: the steel ladle structure of Rapid Alarm while providing a kind of molten steel to leak, solves existing steel ladle in the time of transhipment molten steel, the indiscoverable problem of staff when molten steel flows out from steel ladle gap.
Technical scheme of the present invention: the steel ladle structure of Rapid Alarm when a kind of molten steel leaks, include refractory masses, be steel plate layer in refractory masses outside, on steel plate layer surface, scribble the first insulating moulding coating layer, the first insulating moulding coating layer outside is combustible material layer, scribbles the second insulating moulding coating layer on combustible material layer outer surface.
The steel ladle structure of Rapid Alarm when above-mentioned molten steel leaks, described combustible material layer is made up of rubber, polystyrene, nylon, epoxy resin, polytetrafluoroethylene (PTFE) or polyphenyl alkene material.
The steel ladle structure of Rapid Alarm when above-mentioned molten steel leaks, described the first insulating moulding coating layer thickness is: 8～12mm.
The steel ladle structure of Rapid Alarm when above-mentioned molten steel leaks, described the second insulating moulding coating layer thickness is: 8～16mm.
Beneficial effect of the present invention: compared with prior art, the present invention has increased by the first insulating moulding coating layer in the structure of original steel ladle, combustible material layer and the second insulating moulding coating layer, when molten steel ablation, while puncturing whole steel ladle, molten steel can make the combustible material burning in combustible material layer, in combustible material combustion process, can discharge a large amount of dense smoke, hanging master worker works as and sees that a large amount of cigarettes occurs knowing that leakage has occurred steel ladle in the time of transhipment steel ladle, hanging master worker's device that pushes for emergency, shop personnel can know the accident of having occurred, thereby leave fast the scene of the accident, effectively avoid the generation of personnel casualty accidents.And be coated with the first insulating moulding coating layer can avoid combustible material layer in steel ladle in the situation that not puncturing, while being subject to high temperature, there is spontaneous combustion; Can avoid the molten steel in steel ladle to splash out while being bonded on combustible material layer and be coated with the second insulating moulding coating layer, combustible material burning.Some transformations are done in this invention in the structure of original steel ladle, can, in the time there is molten steel leakage, greatly avoid personnel casualty accidents and occur.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention;
Reference numeral: 1-refractory masses, 2-steel plate layer, 3-the first insulating moulding coating layer, 4-combustible material layer, 5-the second insulating moulding coating layer.
Detailed description of the invention
Embodiments of the invention: the steel ladle structure of Rapid Alarm when a kind of molten steel leaks, as shown in drawings, include refractory masses 1 that the steel ladle of existing use includes and the steel plate layer 2 in refractory masses 1 arranged outside, the present invention scribbles the first insulating moulding coating layer 3 on steel plate layer 2 surface of existing steel ladle, then there is combustible material layer 4 in the first insulation material layer 3 arranged outside, and scribble the second insulating moulding coating layer 5 on combustible material layer 4 outer surfaces.
The temperature of the molten steel in steel ladle is generally 1700 DEG C of left and right, because the burning-point of this different materials is between 350～670 DEG C, for fear of steel ladle do not have ablated, puncture in the situation that, the combustible material layer 4 of being made up of a kind of material in this different materials is because dieseling occurs the high temperature of molten steel, therefore should ensure that the thickness of the first insulating moulding coating layer 3 is: 8～12mm, makes the temperature that is delivered to combustible material layer 4 after refractory masses 1, steel plate layer 2 and the first insulating moulding coating layer 3 below 200 degree.Splash out for fear of the molten steel in steel ladle and drop on combustible material layer 4, cause that combustible material layer 4 burns, therefore scribble the second insulating moulding coating layer 5 on combustible material layer 4, also burn for fear of the material of combustible material layer 4, therefore its thickness is set to: 8～16mm simultaneously.And the insulating moulding coating using can be ZS-1 thermostable heat-isolating coating, the heat insulation and heat control magnitudes table of ZS-1 thermostable heat-isolating coating is as shown in subordinate list 1, while scribbling as can be seen from the table the coating of 8mm thickness, can 250 DEG C of left and right will be reduced to up to the temperature of 1500 DEG C, the burning-point of the complete combustible material lower than combustible material layer 4, thus avoid well combustible material layer 4 to occur the situation of high temperature spontaneous combustion.
