Abstract
The utility model discloses a pure magnesium balling tundish. The pure magnesium balling tundish comprises a tundish body, a cover plate and a partition, wherein a pure magnesium feeding inlet is arranged in the upper part of the tundish body, a molten iron inlet is arranged on the cover plate, and a magnesium vapor outlet is arranged on the partition; the cover plate covers an opening of the tundish body, and the partition is fixedly arranged inside the tundish body, and divides the internal space of the tundish body into a magnesium reaction chamber and a balling reaction chamber; and the magnesium reaction chamber and the balling reaction chamber are communicated by the magnesium vapor outlet, the magnesium reaction chamber is communicated with the pure magnesium feeding inlet, and the balling reaction chamber is communicated with the molten iron inlet. The pure magnesium balling tundish can conduct full balling reaction, and improve the balling effect, the addition amount of the pure magnesium can be reduced, thereby facilitating the later maintenance and clearing.
Description
Technical field
The utility model relates to the ladle in the casting technique, relates in particular to a kind of pure magnesium nodularization bag.
Background technology
Spheroidal graphite cast-iron is the high-strength cast iron that grows up the 1950's, by the nodular cast iron that obtains after nodularization and the inoculation, has effectively improved the mechanical performance of cast iron, has particularly improved plasticity and toughness.The nodularization mode that at present most domestic casting producer adopts is that sandwich is subcontracted method, namely in the casting ladle bottom reactive magnesium chamber is arranged, pour a certain proportion of nodulizer into the reactive magnesium chamber, then cover one deck coverture at nodulizer, prevent that nodulizer from contacting with molten iron too early; The nodulizer that adopts is generally magnesium-rare earth.This sandwich is subcontracted in the method, coverture may be washed out when molten iron pours the nodularization bag, causes the too early and molten iron reaction of nodulizer, causes the magnesium loss, and the magnesium residual quantity is low in the rear molten iron of reaction end, may cause abnormal nodularizing; In addition, the nodularization bag of normal operation is long barrel structure now, and the cleaning of the reaction slag that produces in the production is very difficult.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of pure magnesium nodularization bag, and fully spheroidizing reacion, raising nodularization effect reduce pure magnesium addition simultaneously, are convenient to later maintenance and cleaning.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is: pure magnesium nodularization bag, comprise inclusion, cover plate and dividing plate, and the top of described inclusion is provided with pure magnesium charging aperture, be provided with the molten iron import on the described cover plate, be provided with magnesium steam gas outlet on the described dividing plate; Described cover plate covers on the opening of inclusion, and dividing plate is fixed on inclusion inside, the inner space of inclusion is divided into reactive magnesium chamber and spheroidizing reacion chamber; Described reactive magnesium chamber and spheroidizing reacion chamber are communicated with by magnesium steam gas outlet, and described reactive magnesium chamber is communicated with pure magnesium charging aperture, and described spheroidizing reacion chamber is communicated with the molten iron import.
Said structure in use, at first by pure magnesium charging aperture to the pure magnesium of the indoor interpolation of reactive magnesium, then pass through the molten iron import to the indoor interpolation molten iron of spheroidizing reacion, because the high temperature of molten iron passes to magnesium, magnesium is met high temperature moment gasification, and it is indoor that magnesium steam enters into spheroidizing reacion by magnesium steam gas outlet, produces spheroidizing reacion with molten iron, spheroidizing reacion is abundant, nodularization is effective, can reduce the waste of magnesium material simultaneously.Said structure can not be designed to high barrel structure fully, and is designed to short but barrel structure that cross section is large etc., when cleaning, opens cover plate just can clear up later maintenance and clear up all more convenient.
Preferably, described cover plate is realized opening and closing movement by bar linkage structure, and described bar linkage structure comprises cylinder, free bearing and connecting rod, and described connecting rod is hinged with output shaft and the free bearing of cylinder respectively, and cover plate and connecting rod are fixed; In this structure, by just can conveniently control the folding of cover plate to the control of cylinder, avoid manually-operated.
Preferably, the incline structure poured out for ease of molten iron of the lower wall of the opening of described inclusion.
Beneficial effect: the pure magnesium nodularization bag that the utility model provides, fully spheroidizing reacion, raising nodularization effect reduce pure magnesium addition simultaneously, are convenient to later maintenance and cleaning.
