Изобретение относитс к металлургии , конкретнее к непрерывной разливке металлов.The invention relates to metallurgy, and more specifically to the continuous casting of metals.

Известны кристаллизаторы машин непрерывного лить заготовок (МНЛЗ), со сто щие из широких и узких стенок и устройства дл раздвигани узких стенок непосредственно на МНЛЗ 1.Continuous casting machine molds (continuous casting machines), consisting of wide and narrow walls, and devices for pushing apart narrow walls directly onto the continuous casting machine 1 are known.

Недостатками данного кристаллизатора вл ютс отсутствие стабилизации геометрии отливаемого сечени и сложность конструкции. Большое число шарнирно соединенных элементов и нежестка фиксаци их в рабочих положени х ухудша ет качество литых, заготовок , а сложна конструкци увеличивает эксплуатационные расходы, снижает надежность и долговечность кристаллизатора в работе.The disadvantages of this mold are the lack of stabilization of the geometry of the molded section and the complexity of the design. A large number of pivotally connected elements and their non-rigid fixation in the working positions deteriorates the quality of the cast billets, and the complex construction increases the operating costs and reduces the reliability and durability of the mold in operation.

Цель изобретени - достижение стабилизации геометрии отливаемого сечени заготовок и существенное упрощение конструкции, с одновременным увеличением возможного диапазона ширин отливаемых заготовок.The purpose of the invention is to achieve stabilization of the geometry of the molded section of the blanks and significantly simplify the design, while simultaneously increasing the possible range of widths of the molded blanks.

Поставленна цель достигаетс тем Что неподвижна лшрока стенка крис аллиЗатора снабжена фиксирующими упорами, а подвижна широка стенкаThe goal is achieved by the fact that the fixed wall of the shaft of the allisator is equipped with locking lugs, and the movable wide wall

прижата к узким с помощью балки опорной рамы и двух пружин.pressed against the narrow with a support frame beam and two springs.

Кроме того, неподвижна широка Also immobile wide

с стенка снабжена торцовыми консол ми, вл ющимис опорами дл подвижной широкой стенки, а фиксирующие упоры неподвижной широкой стенки выполнена клиновыми с винтовым приводом jthe wall is provided with end consoles, which are supports for the movable wide wall, and the fixing stops of the fixed wide wall are made with a screw drive j

.д приводы перемещени и фиксации узких стенок расположены на наружной поверхности широкой стенки.The drives for moving and fixing the narrow walls are located on the outer surface of the wide wall.

На фиг. 1 изображен кристаллизатор с опорной рамой в плане; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 35 фиксирующий упор неподвижной широкой стенки; на фиг. 4 - разрез Б-Б на фиг. 3.FIG. 1 shows a mold with a support frame in plan; in fig. 2 shows section A-A in FIG. one; in fig. 35 fixing stop fixed wide wall; in fig. 4 shows a section BB in FIG. 3

На опорной раме 1 с подвижной балк .ой 2 установлена и закреплена неподвижна широка стенка 3 с двум торцовыми консол ми 4, имеющими плоскости скольжени И, по которым может перемещатьс подвижна широка стенка 5 . Дл перемещени подвижной ши рокой стенки 5 в сторону от неподвижной предусмотрены гидроцилиндры 6, т ги 7 и захваты 8, а в обратном направлении - пружины 9, т ги 7 и упоры 10. Основани 11 узких стенок 12On the supporting frame 1 with the movable beam 2, a fixed wide wall 3 is mounted and fixed with two end brackets 4 having glide planes AND along which the moving wide wall 5 can move. To move the movable wide wall 5 away from the stationary, hydraulic cylinders 6 are provided, ti gi 7 and clamps 8, and in the opposite direction springs 9, ti gi 7 and stops 10. Base 11 of narrow walls 12

Claims

30 can be fixed in the working position by a twin screw screw drive 13 and a screw clamp 14, with the drives 13 located on the outer side of the fixed wide wall 3. The fixing stops 15 of the fixed wide wall 3 are wedge and equipped with a screw drive 16. Vertical fixation with the fixed wide the wall 3 to the support frame 1 is made by two wedge fasteners 17 to the planes M. When assembling the mold, the movement on the wide wall 5 is driven along the slip planes H on the console 4 of the fixed wide wall 3. Before By installing the assembled crystalline mash on the support frame 1, hydrocylin drami 6, through the rods 7, move the mobile beam 2 to the extreme position, for example, the locking stops 15 are recessed to the maximum. When the mold is lowered on the plane M, it is simultaneously fixed in the slots 8, Then with the help of springs 9, 7 and 7, stops 10 and hydraulic cylinders 6 put the mold into working position and fill it with stops 15 with full pressure on springs 9, as well as wedge fasteners 17. When adjusting the required width of the cast billet, the movement of the narrow walls 12 is performed directly in the caster using a twin-screw worm drive 13. A rigid fixation of the position of the narrow walls is achieved by the simultaneous action of self-braking worms screw drives 13 and screw clips 14. The location of the drives 13 moving narrow walls 12 on the fixed wall 3 outside it allows, without the size of the caster mold, to provide a large possible range of blank workpieces along the tire. Claim 1. Inventorizer for continuous casting machines, comprising a support frame with a beam, movable and fixed, wide walls, narrow walls and a device for sliding the narrow walls directly on the machine, characterized in that, in order to stabilize the geometry of the cast section and increase the range sizes of cast billets, fixed wide wall of the mold provided with locking lugs, and the movable wide wall is pressed to the narrow with the help of a support frame beam and two springs.

2. A mold according to claim 1, characterized in that the fixed wide wall is provided with end consoles being supports for a movable wide wall.

3. The crystallizer according to claim 1, characterized in that the locking lugs of the fixed wide wall are wedge-mounted with a screw drive.

4. The crystallizer according to claim 1, wherein the actuators for moving and fixing narrow stitches are mounted on the outer surface of the wide wall. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 384602, cl. B 22 D 11/04, 1973. B) F i / K -J4piJ
