Description
Technical field
The utility model relates to a kind of spheroidization apparatus, especially a kind of novel without dykes and dams simplified style spheroidization apparatus.
Background technology
Nowadays the production of spheroidal graphite cast iron experienced by over half a century with application, people to its life degree of depth and range of application quite familiar, in spheroidizing, people are accustomed to operating working method easily, the special nodularization pack processing that the method that wherein pours adopts height/diameter to be greater than 1.5 just experienced by more than 30 year, nowadays some workman adopts special spheroidizing bag and the not general highly low pouring ladle of dual-purpose, compared with the pouring ladle adopting this special spheroidizing bag originally short with employing, the scaling loss of magnesium is few, and specific absorption is high, the nodularization special purpose packet of a lot of producer mostly is uncovered use several years ago, when spheroidizing, in air the contact of oxygen and iron liquid and the chemical reaction of magnesium unrestricted, make in spheroidizing process, to produce a large amount of flue dust and strong magnesium light, cause a large amount of scaling loss wastes of nodulizing agent, so for the shortcoming of this spheroidizing mode, each foundry has in succession found out and has added upper cover to nodularization bag, thus spheroidizing is carried out under the condition of an opposing seal, effectively can reduce the pollution of flue dust and the magnesium light produced in spheroidizing process, but this nodularization bag it need the side of wrapping have lid, lid have partially in pod apertures on one side, the pit forming nodulizing agent with refractory brick as dykes and dams is needed bottom nodularization bag, this nodularization bag there will be two kinds of problems in use for some time: 1, dykes and dams bottom nodularization bag easily damage, there is breach in dykes and dams middle part, thus dykes and dams are not had separate the effect of iron liquid and nodulizing agent, molten iron sweeps away the indentation, there that can occur in the middle of dykes and dams and is directly flushed to nodulizing agent, cause abnormal nodularizing, 2, broken hole is also easily washed open by molten iron in the centre of clad, once the central authorities of lid are broken through by molten iron, molten iron just can pour in nodularization bag from centre, is easy to be flushed on the nodulizing agent at the bag end, causes abnormal nodularizing, produces nodularization waste product, 3, nodularization wraps in the inconvenience in maintaining, first be that warding off of clad is wrapped, because the pod apertures on lid is partially on one side, so just require that warding off refractory materials is in position high recently, pod apertures place, and the central authorities of lid can not be made to be in minimum position, otherwise lid central authorities there will be water storage phenomenon, next is the dam configuration bottom nodularization bag, although dykes and dams have very large effect, but dykes and dams are more not easy to operate when warding off bag, to dykes and dams be put into bottom nodularization bag, also be fixed with refractory materials, this has very difficult operation easier, therefore, just be badly in need of developing a kind of structure simple and easy-operating novel without dykes and dams simplified style spheroidization apparatus, through retrieval, do not find device same or analogous with the utility model device.
Utility model content
It is simple and easy-operating novel without dykes and dams simplified style spheroidization apparatus that the technical problems to be solved in the utility model is to provide a kind of structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of novel without dykes and dams simplified style spheroidization apparatus, its innovative point is: comprise an inclusion, one deck flame retardant coating has been warded off inside this inclusion, a clad is provided with above described inclusion, described clad central position is provided with a pod apertures, and pod apertures two ends become horn-like, use refractory materials to ward off into the frustum of a cone cavity of a ladder bottom described inclusion;
Be provided with nodularization layer from bottom to up in described frustum of a cone cavity, breed layer and tectum, above described frustum of a cone cavity, be provided with a steel plate.
Further, described nodularization layer filling ball agent.
Further, breed layer described in and fill nucleating agent.
Further, described tectum fills insulating covering agent.
Further, the thickness 28mm ~ 31mm of described steel plate.
The utility model has the advantage of: the pod apertures on clad is moved to the central position of clad by the utility model device, when water conservancy diversion molten iron, molten iron is directly rushed in bottom spheroidization device from centre hole like this, molten iron need not turn round, thus just decrease the splash phenomena in the time of falling molten iron, and such clad structure is simple, lid is also easy to safeguard; Original dam configuration is removed by the bottom of nodularization bag, the substitute is the round platform cavity of ladder, in frustum of a cone cavity, place nodulizing agent, nucleating agent and insulating covering agent from bottom to up, and then the top of frustum of a cone cavity arranges steel plate, this structure is simple, easy to use;
Molten iron directly can not be flushed on nodulizing agent in use, otherwise nodulizing agent can be come up, cause abnormal nodularizing, to control beginning opportunity of spheroidizing reacion in addition exactly well, it is start spheroidizing reacion that requirement controls to pour 2/3rds at molten iron, so we arrange a steel plate above frustum of a cone cavity bottom nodularization bag, molten iron is punched in from above on steel plate, and can not be punched on nodulizing agent, therefore would not be come up with regard to nodulizing agent, our steel plate thickness is at 28mm ~ 31mm, when molten iron falls down, steel plate can not melt at once, steel plate can be made to melt at short notice when reaching a certain amount of molten iron, thus complete spheroidizing reacion, this nodularization process stabilization, there is no violent rollover phenomenon, and the loss of magnesium is little in reaction process, there is not vigorous combustion in magnesium, the absorption rate of magnesium just rises, magnesium elements directly and iron liquid merge, eliminate the hidden danger of abnormal nodularizing, and decrease temperature drop, the amount that nodulizing agent adds reduces, cost reduces, and there is no strong magnesium light agent white smoke contamination, meet environmental requirement, manual operation is simple and convenient, the maintaining of nodularization bag is convenient, ward off bag also simple to operation, nodularization pack arrangement simply easily makes, be convenient to wide popularization and application.
Accompanying drawing explanation
Fig. 1 is the novel structural representation without dykes and dams simplified style spheroidization apparatus of the utility model device.
