Description

Изобретение относитс  к черной металлургии и может быть использовано при производстве крупноразмерных сл бов. Известен кристаллизатор дл  непрерывной разливки металлов в слитки пр моугольного сечени , имеющий выпуклые широкие стенки. Отливаемый в такой кристаллизатор слиток имеет вогнутые широкие грани, что необходимо дл  ликвидации искажений профил  слитка вследствие раздути  граней. Однако часто затвердевающа  оболочка слитка оказываетс  неспособной противосто ть ферростатическому давлению жидкой сердцевины, поэтому на гран х .слитка все же возникают выпуклости. Предлагаемый кристаллизатор отличаетс  тем, что его узкие стенки в местах стыка с выпуклыми снабжены срезами, перпендикул рными к ним, а выпуклые стенки - срезами , перпендикул рным.и к поперечной оси кристаллизатора. Па фиг. 1 изображена установка непрерывной разливки, обший вид; на фиг. 2 - разрез по А-А на фиг. 1; на фиг. 3 - схема, по сн юща  действие сил на оболочку слитка; на фиг. 4 - разрез по Б-Б на фиг. 1. Жидкий металл 1 разливают в кристаллизатор 2, который имеет выпуклые широкие внутренние стенки 3, пр молинейные узкие стенки 4 и водоохлаждаемый корпус 5. Затвердевающий слиток выт гивают из кристаллизатора с помощью т нущих роликов 6, которые располагают только по узким гран м слитка 7. Выпр мление слитка осуществл ют ролики 8. Узкие стенки 4 кристалл изатора в местах стыка с широкими стенками 3 снабжены срезами 9, выполненными под углом 90° к ним. Широкие выпуклые стенки в местах стыка с узкими снабжены срезами 10, перпендикул рными к поперечной оси кристаллизатора. Така  конструкци  кристаллизатора обеспечивает необходимую форму слитка, предотвращающую его раздутие. Выход щий из кристаллизатора слиток представл ет собой затвердевшую оболочку 11 .и жидкую сердцевину 12, причем его узкие грани 13 имеют срезы 14 под углом 90° к вогнутым гран м 15. Возникающие в зоне контакта с т нущими роликами 6 силы (показано стрелками В) противодействуют давлению жидкой сердцевины на оболочку. Действие роликов на вогнутую оболочку оказываетс  таким же, как в несущей арке 16, наход щейс  под равномерной нагрузкой и опирающейс  посредством укосин 17, имеющих скосы 18 (см. фиг. 3). Срезы 10, выполненные на выпуклых стенках кристаллизатора и соответственно на слитке, обеспечивают поддержание слитка роликами 6 при выт гивани« . При приложении необходимого давлени  вогнутость граней слитка может сохран тьс  и регулироватьс .The invention relates to ferrous metallurgy and can be used in the production of large-sized slabs. A mold for continuous casting of metals into ingots of rectangular cross section, having convex wide walls, is known. The ingot molded into such a mold has concave wide faces, which is necessary to eliminate distortions of the ingot profile due to the swelling of the faces. However, often the solidifying shell of the ingot is not able to withstand the ferrostatic pressure of the liquid core, therefore there are still bulges on the faces of the slug. The proposed mold is characterized in that its narrow walls at the junction points with convex ones are provided with cuts perpendicular to them, and the convex walls are cuts perpendicular to the transverse axis of the mold. Pa figs. 1 shows a continuous casting plant, a general view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a diagram explaining the effect of forces on the ingot shell; in fig. 4 is a section along BB in FIG. 1. Liquid metal 1 is poured into a crystallizer 2, which has convex wide inner walls 3, straight linear walls 4 and a water-cooled body 5. A solidifying ingot is pulled out of the crystallizer with pull rollers 6, which are placed only along narrow faces of an ingot 7 The straightening of the ingot is carried out by the rollers 8. The narrow walls 4 of the crystal of the isolator at the junction points with the wide walls 3 are provided with cuts 9, made at an angle of 90 ° to them. The wide convex walls at the junction with the narrow ones are provided with cuts 10, perpendicular to the transverse axis of the mold. Such a design of the mold provides the necessary shape of the ingot to prevent its expansion. The ingot outgoing from the mold is a hardened shell 11. And a liquid core 12, and its narrow faces 13 have cuts 14 at an angle of 90 ° to the concave faces 15. The forces appearing in the contact zone with pulling rollers 6 (shown by arrows B) counteract the pressure of the liquid core on the shell. The action of the rollers on the concave shell is the same as in the carrier arch 16, which is under uniform load and is supported by the braces 17 having bevels 18 (see Fig. 3). Sections 10, made on the convex walls of the mold and, accordingly, on the ingot, ensure the maintenance of the ingot by the rollers 6 while drawing. By applying the necessary pressure, the concavity of the faces of the ingot can be maintained and adjusted.
