The invention relates to ferrous metallurgy and can be used in the processing of steel with inert gases with the aim of homogenizing and refining of non-metallic inclusions and dissolved gases.

There is the brick which is known for blowing the metal gases, consisting of a dense refractory (for example fire clay, kaolin, dinas etc.) with through cracks, with clearances of 0,03-0,5 mm, and the ratio of the total area of gaps in the section to the total area of this section is proportional to the average size of the gap in the brick and is 0,0006-0,0040 (a.c. USSR JV«570453 B 22 D 41/00 30. 08. 77.

The main disadvantage of such bricks is that in contact with brick slag melts is its delay in the flat capillary crack-shaped gap and stop blowing. The brickwork is expanding and sealing while it's heating. In this case due to compaction happens the bulk pressure of the bricks, which leads to a narrowing of the gap, moreover, the more rapid heating, the smaller the gap, until the complete closure and the loss of gas-tightness. Known gas-tight brick can be used only in one-dimensional position, in this example, on the edge, with the scheme of the working layer of masonry at the end, this brick is not suitable.

The closest analogue is the section for processing metal with gases, which is made up of separate components, contracted with a wire, which is entwined around the sections, which are located between the through-hole crack-shaped capillary holes, made by a gap between the elements formed by the protrusion in 0,220- 0,170 mm, performed on the lateral surfaces of the elements. (Patent of Ukraine JSI 35356, 10. 09. 08. Bui. Jfe 17).

The disadvantage of the closest analogue is the fact that wire is used as a part of the retaining element. The contraction of the individual elements with the thin wire does not give reliable results, because it is stretched during installation and the elements become less dense, and the thick wire is too tough and extreme elements split and the whole section quickly breaks down. In the contraction of elements with the thin wire, efforts in the place of twist are much higher than on the opposite side. That is why, during the installation it is necessary to conduct further tightening of the wire. If you do not, then during lifting section wire is stretched and the elements fall. But even after pulling, the wire gap became significantly lower than it is needed for technology (up to 2 mm instead of 0,2).

In addition, the drawback is that the capillary holes for the gas outlet formed protrusions, which are located on the elements. The mount technology of such section has shown that it is impossible to fix the seal to the moment when gap between sections and lined is poured with refractory concrete. When casting refractory concrete in the side gap fall laitance, which largely overlaps the passage of gas into the molten metal. In addition this figure is spontaneous and each section should be further tested for gas-tight. The installation must be very careful to watch a density of applying the elements to each other. If you add tabs to a ledge and a smooth surface to smooth the distance between the rows of capillaries will be twice bigger then it needed in the instruction, and the size also will be twice bigger than there is a need for the work of device. Maximum thickness of the capillary should not exceed 0,2 mm, since the greater thickness of it the liquid metal enters freely into the hole freezes there and section breaks down.

In addition, the purging device must have a "Security Beacon", which shows when you need to replace hardware components of the purge. In the known section such element is absent, which is a violation of security of the device and metallurgical capacity in general.

In the base of invention is the aim to create a section for processing liquid metal with gas, in which by changing the design part of the retaining element and sealing the sections it is possible to increase its mounting strength while ensuring is given for the direction and intensity of the steady flow of gas.

The problem is solved by the fact that the proposed section for processing liquid metal with gases, made up of separate components connected by a coupler, made up of separate components connected by a coupler between which the capillary openings for gas outlet are situated, in which, according to the invention, the capillary holes for the gas outlet are formed with at least two different separators, located between the elements at their opposite edges. The section has at least one longitudinal through hole, which is situated at a distance of maximum wear and tear from the top of the section, and a coupler is designed as mounting rod, which is which is located in this hole, in addition, the side surface sections have a sealing coating.

In a preferred embodiment, the section has two longitudinal through holes, located at the distance of maximum wear and tear from the top section in each of which is the mounting rod situated.

In some embodiments as a sealant covering it is used the silicate glue or AHF, or the refractory cement.

In a preferred embodiment, the section has a rectangular shape. But it can also have a square or circle.

Mounting rods are made solid or composing.

In a preferred embodiment, the dividers are made in the forms of metal or plastic strips of a width not exceeding 10 mm. Separators can also be made in the form of plates or calibration items.

Collection contained in an independent claim of essential features is necessary and sufficient for all cases of using the invention.

Between the essential features of the invention and the technical result there is a causal relationship, which is explained as follows. In the application of metal rods tightening effort to carry out the nuts, and the force vector, thus, has the direction strictly along the axis of the rod. That is, Turnbuckle rod works only on the gap. Tie rods have a diameter of 6-8 mm, the wire is not more than 1 mm, and that is, strength of tie rods is ten times higher, so after blowing section its deformation is absent. These sections can be transported, transferred, turned over without a risk of the damage. Internal arrangement of the rods does not allow items to shift and disrupt the integrity of the section as a whole.

There is such diameter of the rod that is noticeable at the maximum wear of the section and can play the role of "Security Beacon". It is very important index because its absence can lead to emergency.

The presence of dividers from the one side allows you to pull off a section with a great effort, what increases it mounting strength from the other side- provides a constant fixed size of the capillary openings for the gas outlet, providing specified in direction and intensity of a steady stream of gas.

On the one hand the presence of a sealing coating increases the solidity; it means it increases the mounting strength of the section; from another- excludes the possibility of gas exit through the side surface sections, that contributes to a given direction and intensity of a stable gas flow.

Through-hole in the longitudinal section can be done after the assembly of the elements, but you can make holes in each element, and then collect them to form a single through hole. In the second case, the elements that have a hole, is much easier to collect in the section, because tie rods are the conductors and elements themselves are put into place and does not need any special trends, it means that installation of such section is simpler and more technological.

The invention is explained by drawings where:

On Fig.l is described the section in assembly. On Fig.2 is described the section, installed in the lining of the shell of metallurgical capacity and the variants of using.

On Fig.3 is described the variants of collecting section are shown.

Section for processing liquid metal with gases is produced from individual elements 1, which connected with tie rods 2. Between elements 1 there are situated capillary openings 8 for gas outlet, formed with stripes 6, which are set between elements 1 from different sides. Section has two longitudinal through holes 4, which are situated at the distance maximum wear of section and lining 3 in general, counting from the top side of the section, which placed the tie rods 2 and outside sealing layer of heat-resistant adhesive 5. Contraction of the elements is done by nuts 7.

Items are manufactured on a mechanical press, which is designed for semidry pressing of refractory products from powders with humidity 4-8%. Pressing behavior sided, single-stage with four at the same time pressed bricks.

There are some specific examples of using the sections.

Example 1 ^st

Foundry ladle with a capacity of 16 tons has brick lining 3.

Working layer of the bottom is made of refractory concrete. The thickness of the layer is 300 mm.

The vent device consists of three sections that are installed on the butt with a distance of 40 mm relatively to each other and has a size 530x600 mm. Section consists of 12 elements 1, which have a height of 300 mm, width 150 mm, length 600 mm. The vent device is installed in the collector bucket, which is located on the reinforcing layer of ladle lining. Each section is contracted by two compression fittings rods 2 each 6 mm in diameter that are located in the hole 4 of 8 mm diameter elements. Then they form a working layer of the furnace by pouring the space around the device and purge between the sections of refractory concrete. Bucket serves to dry and after the heating is directed to filling with liquid metal. While a metal bucket is filling through capillary openings purge device 8 the gas is being supplied.

Example 2 ^nd

Furnace (DS-25 MT) has a thickness of the working layer 160 mm.

Work bottom layer is made of refractory concrete. The thickness of working layer is about 300 mm.

The vent device consists of three sections, set on edge with a distance of 40 mm relatively to each other and has a size in 300x600 mm. Section consists of 12 elements 1, which have a height of 300 mm, width 150 mm, length 600 mm. The vent device is installed in the collector bucket, which is located on the reinforcing layer of ladle lining. Each section is contracted by two compression fittings rods 2 each 6 mm in diameter that are located in the hole 4 of 8 mm diameter elements. Then they form a working layer of the furnace by lying around scavenging devices, and between the sections of the sealing of the sealing layer from MKS-72 mixed with AHF. After this, they make padding of working layer on the adopted technology. With the appearance of liquid metal through capillary openings 8 gases are supplied.

These examples show that the using of individual elements significantly enhances the assembly of sections because they can be laid either on the end or edge and ability of having section high as 300 and 150 mm when the element is laid on the edge. From individual elements can be produced purge the device as small foundries and in the large steel ladles. Application of certain elements will be installed purge unit of any configuration and area, directly adapted to a given bucket technology.

Elements can be manufactured in other sizes, for example 230x114x65,

230x114x40, 300x150x65 and others. That is such a design section and the purge unit in general is structurally strong, transportable, fit and can be mounted in many versions of the system and adapt to all containers of a metallurgical capacities.
