Abstract

The utility model discloses a spheroidizing bag comprising a bag body 1 and a rotation shaft 2. A cover bag 3 is disposed at the top portion of the bag body 1. An opening 4 is installed inside the cover bag 3 and communicated with the bag body 1. The spheroidizing bag with the structure is used to spheroidize the cast iron, the dust and magnesium light are little, the working environment is good and the manufacture cost is low.

Description

The spheroidizing bag

The utility model relates to a kind of production equipment of spheroidal graphite cast iron, in particular, is a kind of spheroidizing bag.

The spheroidizing bag of prior art is generally uncovered structure, and molten iron directly is injected in the nodularization bag, and in the spheroidizing process, flue dust and magnesium light are more, and magnesium absorption rate is lower.

The purpose of this utility model is to provide a kind of flue dust and magnesium light is few, good work environment, spheroidizing bag that cost is low.

The utility model is achieved in that a kind of spheroidizing bag, comprises inclusion and rotating shaft, and this inclusion top is provided with the lid bag, in the lid bag hole is set and communicates with inclusion.

The utility model has the advantages that: after adding a cover, iron liquid liquid level is subjected to certain gaseous tension in the nodularization bag, spheroidizing is being carried out under the anoxybiotic state relatively, reduce boiling, improved the specific absorption of nodularization element, reduced temperature loss, no metal splashes, flash of light when having covered nodularization and smog have improved work situation, have reduced production cost.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Accompanying drawing is the utility model sectional view.

As seen from the figure, inclusion 1 top is installed lid bag 3 is set, and has hole 4 in the lid bag 3 and communicates with inclusion 1 inside, and during spheroidizing, molten iron at first injects in the lid bag 3, enters in the inclusion 1 by hole 4 then, and hole (4) diameter calculates with following formula, $D=2.2\sqrt{\frac{W}{t\sqrt{h}}}$

Wherein, D is hole (a 4) diameter, unit centimetre, and W is for handling the iron liquid measure, and unit kilogram, t are the spheroidizing reacion time, and unit second, h is iron liquid height in the lid bag 3, unit centimetre.Utilize this formulae design hole 4 diameters, the iron notch speed of tapping a blast furnace is complementary with the iron speed of going into of lid bag 3 in inclusion 1, prevent that molten iron from overflowing lid bag 3 and molten iron can not make hole 4 sealings fully, can revise in practice by the D value that this formula calculates, to reach best effect.

For making the spheroidizing bag be easy to vert, compare safety simultaneously, rotating shaft 2 Position Design are at the position of centre of gravity of whole spheroidizing bag.

Compare with traditional spheroidising bag, use this device, can shelter 90% with On magnesium light, improved the absorptivity of magnesium, strengthened the nodularization effect, reduced and closed The gold consumption is greatly improved work situation.

Claims (3)

1. a spheroidizing bag comprises inclusion (1) and rotating shaft (2), it is characterized in that: this inclusion (1) top is provided with lid bag (3), in the lid bag (3) hole (4) is set and communicates with inclusion (1).

2. spheroidizing bag according to claim 1 is characterized in that: described hole (4) diameter calculates with following formula,

Wherein, D is hole (a 4) diameter, unit centimetre, and W is for handling the iron liquid measure, and unit kilogram, t are the spheroidizing reacion time, and unit second, h is iron liquid height in the lid bag, unit centimetre.
