In known converters, the additives are fed to a drainage chamber situated in the isibiornib, the wall of which has openings for the passage of the melt. The introduction of magnesium into iron alloys is technically the simplest and most economical method of producing iron-carbon casting alloys with spheroidal graphite. There is also a known device having an integrated, externally charged additive chamber located on the at least in part of the base surface inside the converter. The boundary wall of this chamber has a number of openings. The hole for loading the chamber with additives is a closed plug. The disadvantage of these devices is that the holes made in the wall of the chamber are not accessible from the outside and if these holes are caught, they cannot be cleaned without damaging the hole. The aim of the invention is to make openings in the wall of the chamber in such a way that they can be accessed through the batch opening. In order to achieve this goal, it was decided according to the invention to make the converter in such a way that the axes of the holes in the wall of the additive chamber are directed towards The subject of the invention is described in detail in the embodiment in the drawing, which shows the converter in longitudinal section together with a tilting device. The converter 15 is provided with a tilting device 16. The converter 15 is fitted with a casing in a support flange 1 (7), which is connected to the support frame 18 is detachable from the support frame 18. Support frame 18 is pivotally connected to the tilting device 16. Loading hole Ii9 (for watercourse The hopper 20 is closed with a hinged lid 21. The loading opening is also an opening for emptying the converter. The molten metal 20 fills the converter 15 in its horizontal position up to the filling height 23. In the base surface 22 of the inside of the converter there is a chamber 6 for the additives. The chamber 6 is bounded by a wall 5 having, for example, the shape of an arch, which is provided with holes 3. 4. The chamber 6 is so constructed that, in the horizontal position of the converter 15, the interior of the chamber 6 does not come into contact with the molten metal 20 but is above the filling height 23. The batch 9 of the chamber 6 is preferably provided with a cover with a quick-release device. Axis 8 of the charging opening 9 is preferably arranged such that it forms a bisector of the angle 7 between the axes 1 and 2 of the openings 3 and 4. The charging opening is so selected that the distance 13 of the axis 1 or 2 from the wall 12 of the opening is The batch 9 is equal to or greater than the distance 11 or 11 'of the axis 1, 2 from the wall 14, 14' of the opening 3, 4. The openings 3, 4 in order to change or close the cross section of the opening may be provided with replaceable inserts . A variant of the converter design consists in providing the holes 3, 4 in the wall 5 of the chamber 6 with inserts, which are made of a material such as additives brought to the chamber 6. The principle of the converter according to the invention for the treatment of alloys is based on reducing the molten metal 20 with easily evaporating additives, in which the converter 15 is tilted to a vertical position. The advantages obtained by the invention are that the holes in the wall of the chamber are easily accessible through the feed opening, so that the cross-section of these holes can be checked before each time the chamber is loaded with additives, which ensures smooth processing of the alloy. 82361 It is also certain that when the holes are checked, their narrowing can be easily removed. * For the treatment of iron-carbon alloys with easily evaporating additives, especially with technically pure magnesium comprising a closable and at least partially located at the base surface of the casting vessel, an externally charged chamber, the wall of which has openings at different distances from the base surface through which the alloy contained in the converter enters into communication with it when tilted. in addition, characterized in that the axes (1, 2) of the openings (3, 4) in the wall (5) of the chamber (6) are directed towards the feed opening (9). 2. Converter according to claim The method according to claim 1, characterized in that the axis (8) of the feed opening (9) is a bisector of the angle (7) formed by the axes (1, 2) of the holes (3, 4) and the distance (11, 11 ') of the axis ( 1,2) of the openings (3,4) from the walls (14, 14 ') of these openings is equal to or greater than the distance (13) of the axis (1,2) from the wall (12) of the feed opening (9). 3. Converter according to claim A method as claimed in claim 1, characterized in that the holes (3, 4) are provided with replaceable inserts. 4. Converter according to claim 3. The method of claim 3, characterized in that the inserts are made of the same material as that of the chamber (6). DN-7 - Zam. 453/76 Price PLN 10 PL
