Abstract
Prolong a kind of usage period of blow purifying device of metallurgical tank.This is provided with a supporting member (1) that a plurality of receptive cavities (2) are arranged, and each receptive cavity holds a gas permeable brick (5).A pipeline (3) leads to a web plate (12) from each receptive cavity (2).
Description
The present invention relates to a kind of blow purifying device that is positioned on metallurgical tank bottom or its wall.
Utilize a kind of like this blow purifying device that gas is blown into melt.This bubbling device has a gas-pervious gas permeable brick, and this gas permeable brick is depleted in the course of the work.If gas permeable brick is depleted, just vessel empty and cooling must be changed gas permeable brick.The usage period of gas permeable brick is short more, will often interrupt running more.Wish breaks in production as few as possible.
Task of the present invention provides a kind of blow purifying device that starts described type, realizes prolonging the usage period of gas permeable brick structure by this device.
Therefore according to the present invention, above-mentioned task is resolved in the blow purifying device of the described type of beginning, a fire-resistant supporting member that has a plurality of receptive cavities is set in this device, and each receptive cavity holds a gas permeable brick, and a pipeline leads to a web plate from each receptive cavity.
Gas permeable brick puts into operation successively in this blow purifying device.When first block of gas permeable brick was closed, its gas input was cut off, and another piece gas permeable brick is just connected the gas input.
Another advantage of this blow purifying device is, has reduced the danger that burn in gas leakage or molten bath.If because even in the gas permeable brick one close fully, can not cause the molten bath to be burnt yet.This supporting member prevents this situation.
Below a described embodiment provide favourable embodiment of the present invention.In the accompanying drawings,
Fig. 1 illustrates the sectional view of supporting member,
Fig. 2 illustrates the vertical view of supporting member,
Fig. 3 illustrates a gas permeable brick, with respect to the profile of Fig. 1, and
Fig. 4 illustrates a web plate that is used for supporting member.
A supporting member 1 has a plurality of (being three in an embodiment) round shape receptive cavity 2, and it is open upwards.A pipeline 3 feeds each receptive cavity 2 from the below, lead to a groove 4 to pipeline 3 volutions, and this groove is arranged on the bottom side of supporting member 1.
Supporting member 1 is made of a kind of airtight refractory ceramic material.
In receptive cavity 2, be filled with gas permeable brick 5(and see Fig. 3).Gas permeable brick 5 is made of a kind of permeable-gas ceramics material, and is contained in the doubleshell 6 of being made up of an inner cylinder 7 and out cylinder 8.One gap 9 is arranged between out cylinder 8 and the inner cylinder 7.
The metallic interconnect 12(that in groove 4 a suitable steel is installed sees Fig. 4).
Gas permeable brick 5 inserts receptive cavity 2.And passing pipeline 3, copper metal gas pipe 11 extends to web plate 12 always.Flue 11 welds together with web plate 12.
A flue 11 is connected with a gas inlet pipe at web plate 12, so that this blow purifying device operation.This moment, Purge gas flowed into melt through flue 11 and gas permeable brick 5.Portion gas enters gap 9 by hole 10 and 9 upwards flows from the gap.Supply with make-up gas to melt on the one hand whereby, produce protective atmosphere on the other hand around supporting member 1.
If one in the gas permeable brick 5 is closed, another gas permeable brick 5 is just connected the gas input so.This is not needed to change supporting member 1 and thereby do not need breaks in production.
Claims (6)
1, be positioned at bottom the metallurgical tank or the blow purifying device on the wall, it is characterized in that, it has a fire-resistant supporting member (1) that has a plurality of receptive cavities (2), and each receptive cavity holds a gas permeable brick (5), and a pipeline (3) leads to a web plate (12) from each receptive cavity (2).
2, the described blow purifying device of claim 1 is characterized in that, fixes the flue (11) of an insertion pipeline (3) on every block of gas permeable brick (5).
3, the described blow purifying device of claim 2 is characterized in that, flue (11) welds together with web plate (12).
4, each described blow purifying device during aforesaid right requires is characterized in that receptive cavity (2) and gas permeable brick (5) are cylindrical.
5, each described blow purifying device during aforesaid right requires is characterized in that gas permeable brick (5) has a doubleshell (6) that has gap (9), and gas enters gap (9) from gas permeable brick (5).
6, each described blow purifying device during aforesaid right requires is characterized in that supporting member (1) is made of a kind of airtight refractory ceramic material.
