Abstract
The invention discloses the steel ladle structure of Rapid Alarm when a kind of molten steel leaks, include refractory masses, it is steel plate layer outside refractory masses, the first insulating moulding coating layer is scribbled on the surface in steel plate layer, be combustible material layer outside first insulation material layer, combustible material layer outer surface scribble the second insulating moulding coating layer.Compared with prior art, the present invention adds 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, when puncturing whole steel ladle, molten steel can make the combustible material in combustible material layer burn, a large amount of cigarettes can be discharged in combustible material combustion process, hanging master worker works as when transporting steel ladle sees that a large amount of cigarettes occurs knowing that steel ladle there occurs leakage, hanging master worker pushes for emergency device, shop personnel can know the accident of there occurs, thus it is ready-made to leave accident fast, effectively avoid the generation of personnel casualty accidents.
Description
Technical field
The present invention relates to the steel ladle structure of Rapid Alarm when a kind of molten steel leaks, belong to steel-making equipment technical field.
Background technology
After molten steel is good, transport through steel ladle.The steel ladle of present use is all use steel plate to make tubbiness, inside the steel plate layer of barrel-like structure, then build the refractory masses having refractory material to be made.But existing frequent appearance at present occurs because steel ladle damages the accident causing molten steel to leak, and the accident that molten steel leakage occurs generally is mainly 2 kinds of situations, a kind is that whole steel ladle tilts to cause the molten steel in steel ladle to flow out; Another is steel ladle Long-Time Service, and molten steel constantly carries out ablation to steel ladle constituent material, finally punctures whole steel ladle thus causes molten steel to flow out.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, greatly can avoid the generation of accident.But for the second accident, because first molten steel is flow out from tiny gap, general staff is difficult to find this gap in the process checking steel ladle.When causing steel ladle to occur when transporting molten steel to leak, 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 when providing a kind of molten steel to leak, solving existing steel ladle when transporting molten steel, staff's indiscoverable problem 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, it is steel plate layer outside refractory masses, the first insulating moulding coating layer is scribbled on the surface in steel plate layer, be combustible material layer outside first insulating moulding coating layer, combustible material layer outer surface scribble the second insulating moulding coating layer.
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 first insulating moulding coating layer thickness is: 8 ~ 12mm.
The steel ladle structure of Rapid Alarm when above-mentioned molten steel leaks, described second insulating moulding coating layer thickness is: 8 ~ 16mm.
Beneficial effect of the present invention: compared with prior art, the present invention adds 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, when puncturing whole steel ladle, molten steel can make the combustible material in combustible material layer burn, a large amount of dense smoke can be discharged in combustible material combustion process, hanging master worker works as when transporting steel ladle sees that a large amount of cigarettes occurs knowing that steel ladle there occurs leakage, hanging master worker pushes for emergency device, shop personnel can know the accident of there occurs, thus leave the scene of the accident fast, effectively avoid the generation of personnel casualty accidents.And be coated with the first insulating moulding coating layer and can avoid combustible material layer in steel ladle when not puncturing, there is spontaneous combustion when being subject to high temperature; And be coated with the second insulating moulding coating layer the molten steel in steel ladle can be avoided to splash out when being bonded on combustible material layer, combustible material burns.Some transformations are done in this invention in the structure of original steel ladle, when molten steel occurring and leaking, can occur with greatly avoiding personnel casualty accidents.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Reference numeral: 1-refractory masses, 2-steel plate layer, 3-first insulating moulding coating layer, 4-combustible material layer, 5-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, the refractory masses 1 that the steel ladle including 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 the surface in the steel plate layer 2 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 surface.
Combustible material layer 4 can be made up of rubber, polystyrene, nylon, epoxy resin, polytetrafluoroethylene (PTFE) or polyphenyl alkene material, all can send a large amount of dense smoke in these material combustion processes.
The temperature of the molten steel in steel ladle is generally about 1700 DEG C, burning-point due to this different materials is between 350 ~ 670 DEG C, in order to avoid steel ladle when do not have ablated, puncture, dieseling is there is in the combustible material layer 4 be made up of a kind of material in this different materials due to the high temperature of molten steel, therefore should ensure that the thickness of the first insulating moulding coating layer 3 is: 8 ~ 12mm, make to be delivered to the temperature of combustible material layer 4 below 200 degree after refractory masses 1, steel plate layer 2 and the first insulating moulding coating layer 3.Drop on combustible material layer 4 in order to avoid the molten steel in steel ladle splashes out, combustible material layer 4 is caused to burn, therefore on combustible material layer 4, scribble the second insulating moulding coating layer 5, simultaneously also in order to avoid the material of combustible material layer 4 burns, therefore its thickness is set to: 8 ~ 16mm.And the insulating moulding coating used can be ZS-1 thermostable heat-isolating coating, the heat insulation and heat control magnitudes table of ZS-1 thermostable heat-isolating coating as shown in appendix 1, when scribbling the coating of 8mm thickness as can be seen from the table, temperature up to 1500 DEG C can be reduced to about 250 DEG C, completely lower than the burning-point of the combustible material of combustible material layer 4, thus combustible material layer 4 is avoided to occur the situation of high temperature spontaneous combustion well.
