Description
Technical field:
The utility model relates to a kind of spheroidization device of foundry production, specifically a kind of teapot nodulizing bag.
Background technology:
At present, what the lighter nodularization mode of single bag nodularization iron water amount adopted mostly is uncovered spheroidising, a large amount of dust when causing nodularization, the nodulizer addition is big, decaying spheroidisation fast and a large amount of molten iron splash, and causes environmental pollution, production cost increase, unstable product quality and has increased labor intensity of operating personnel.Simultaneously, because mostly the used spheroidization device of spheroidising is special-purpose spheroidizing reacion bag, will subcontract after the molten iron nodularization, the molten iron after the nodularization injects teapot formula pouring ladle and carries out follow-up cast, has the degenerate problem after the molten iron nodularization.The patent No. is 200620162271, the applying date is on December 26th, 2006, denomination of invention for the patent disclosure of teapot formula sealing nodularization pouring ladle the integrative-structure of a kind of nodularization bag and pouring ladle.Because the sprue gate when charging aperture during nodularization and cast is provided with its complex structure, inconvenience during use respectively; And its nodularization chamber directly communicates with the sprue gate, during nodularization, easily causes escaping of magnesium vapor, and simultaneously, the sprue gate is worn-out mouthful ladle spout, and is big with the air contact area, and molten iron temperature descends fast.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, and is easy to use, and the teapot nodulizing bag that the nodulizer utilization rate is high can be made pouring ladle simultaneously again and use.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of teapot nodulizing bag, it comprises inclusion, bottom in the inclusion is provided with dykes and dams, the bottom of inclusion is divided into feed space, nodularization chamber, and the top of inclusion is provided with simply connected sealing strip lid, and a side of inclusion is provided with Hu Zui, the bottom of inclusion is provided with the molten iron that is communicated with Hu Zui and imports and exports, and feed space is imported and exported by molten iron and is communicated with Hu Zui.
Hu Zui described in the utility model is funnel tubular type Hu Zui, and the diameter of its molten iron access way is 100mm-120mm.
The height of dykes and dams described in the utility model is 200mm-250mm, and the volume of nodularization chamber is 0.02 cubic metre-0.03 cubic metre.
Molten iron described in the utility model is imported and exported suitable for readingly is lower than dykes and dams upper edge 50mm-100mm.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple and reasonable for structure, nodularization, be cast in the bag and carry out, during spheroidizing reacion, the teapot bag is in sealing state substantially, the absorptivity of magnesium can reach more than 85%, reduce the addition of nodulizer, also reduced the tapping temperature of molten iron, thereby reduced production cost; Simultaneously,, alleviated labour intensity, improved working environment and the pollution that has reduced atmosphere because the teapot bag is in sealing state substantially.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the metallograph after the utility model nodularization.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of teapot nodulizing bag, it comprises inclusion 6, bottom in the inclusion 6 is provided with dykes and dams 5, the bottom of inclusion 6 is divided into feed space 2, nodularization chamber 4, and the top of inclusion 6 is provided with simply connected sealing strip lid 7, and a side of inclusion 6 is provided with kettle mouth 1, the bottom of inclusion 6 is provided with the molten iron that is communicated with kettle mouth 1 and imports and exports 3, and feed space 2 is imported and exported 3 by molten iron and is communicated with kettle mouth 1.
Kettle mouth 1 described in the utility model is funnel tubular type Hu Zui, and the diameter of its molten iron access way is 100mm-120mm (present embodiment is 120mm).
The height of dykes and dams 5 described in the utility model is 200mm-250mm (present embodiment is 230mm), and the volume of nodularization chamber 4 is 0.02 cubic metre-0.03 cubic metre (present embodiment is 0.03 cubic metre).
Molten iron described in the utility model import and export 3 suitable for readingly be lower than dykes and dams 5 upper edge 50mm-100mm (present embodiment is 100mm).
During the utility model work, open simply connected sealing strip lid 7 earlier, add nodulizer, close simply connected sealing strip lid 7 again.Molten iron is from kettle mouth 1 turnover, and during nodularization, molten iron is imported and exported 3 from kettle mouth 1 by molten iron and entered that the back flows into feed space 2 earlier in the inclusion 6, crosses dykes and dams 5 then and overflows into nodularization chamber 4 and carry out nodularization.The molten iron temperature that at first flows into of nodularization is lower like this, and secondly molten iron can directly not be flushed on the nodulizer, so the nodularization time is delayed and reversal is more steady, the time of vigorous reaction be substantially molten iron rise to bag high more than 1/3.Simultaneously, molten iron flows into from kettle mouth 1, will bring in the inclusion 6 after the fusing of the residue on kettle mouth 1 wall.Because during nodularization, the teapot bag is in sealing state substantially, magnesium vapor after the nodularization is difficult to escape, played good retarding action for the decline of molten iron, improved the absorptivity of magnesium, can reduce the addition and the nodularization more stable quality (see figure 2) of nodulizer, the adding of nodulizer can drop to 1.3%-1.5% from 2.0%-2.2% under the situation of same base iron, calculate by 100T nodularization every day molten iron, can save nodulizer 700kg-800kg, press 8000 yuan/T of nodulizer and calculate, save cost every day more than 5600 yuan.
After nodularization is finished, open simply connected sealing strip lid 7, remove the gred, enter, so the slag in the molten iron can more steadily float, can dispose through slagging-off because molten iron is bottom from inclusion 6.
During cast, molten iron flows out from kettle mouth 1 to be poured into a mould, and slag residual in the molten iron can be kept off in bag, thereby not enter the inherent quality that product improves product.
Because the teapot bag is in sealing state substantially, nodularization, be cast in the bag and carry out, alleviated working strength of workers, simultaneously, alleviated the electric furnace load, in the past with uncovered bag nodularization, molten iron temperature in the electric furnace must be controlled at more than 1540 °, as long as and have about 1500 ° now just much of thatly, furnace power is from 580kw, can drop to the temperature that just can keep spheroidising about 520kw, greatly reduce power consumption, saved the energy, and, a large amount of dust during nodularization all are enclosed in the ladle, have improved working environment and the pollution that has reduced atmosphere.
