Description

Изобретение относится к области металлургии, в частности к полуне-. прерывному или непрерывному литью металлов.The invention relates to the field of metallurgy, in particular to half. continuous or continuous casting of metals.

Известен электромагнитный кристаллизатор для непрерывной и полунепрерывной разливки металлов, содержащий корпус, крышку, экран из немагнитного материала и индуктор.. <Known electromagnetic crystallizer for continuous and semi-continuous casting of metals, containing a housing, a cover, a screen of non-magnetic material and an inductor .. <

Недостатком известного кристаллизатора являетс$ то» что он не обеспечивает безопасного рабочего напряжения при отливке слитков периметром более 1,5 м.A disadvantage of the known mold is that it does not provide a safe working voltage when casting ingots with a perimeter of more than 1.5 m.

С целью обеспечения безопасного ’ рабочего напряжения при отливке слитков периметром более 1,5 м в предложенном кристаллизаторе индуктор выполнен из отдельных частей по периметру, причем каждая часть подсоединена 20 к двум источникам тока.In order to ensure safe ’operating voltage when casting ingots with a perimeter of more than 1.5 m in the proposed mold, the inductor is made of separate parts around the perimeter, with each part connected to 20 to two current sources.

На фиг. 1 и 2 показан предложенный кристаллизатор.In FIG. 1 and 2 show the proposed mold.

Кристаллизатор состоит из корпуса 1, экрана 2 и индуктора 3. Индуктор состоит из отдельных частей, по периметру входящих в общий контур с источником тока, что обусловливает наличие не одного токоподвода, а двух или более. Учитывая, что для разливки слитков большое значение имеет форма охлаждающей струи и точное количество подаваемого охладителя, . щель для направления охладителя об‘ разована с одной стороны экраном, ' а с другой - поясом 4 из эпоксидной смолы, поверхность которой точно копирует поверхность экрана, обращенную к ней. Экран выполнен из нержаве⁰ ющей стали.The mold consists of a housing 1, a shield 2, and an inductor 3. The inductor consists of individual parts along the perimeter of a common circuit with a current source, which determines the presence of not one current supply, but two or more. Given that for the casting of ingots, the shape of the cooling stream and the exact amount of coolant supplied are of great importance. the slit for guiding the cooler is 'formed on one side by a screen,' and on the other by an epoxy belt 4, the surface of which exactly copies the surface of the screen facing it. The screen is a stainless ⁰ steel rail.

Охладитель через отверстия в корпусе подается к спрейеру, состоящему из экрана и регулировочной планки 5, которая имеет возможность пе5 ремещаться в горизонтальной плоскости при помощи винта. Проходя через щель и стенки по экрану, охладитель попадает на поверхность слитка.The cooler through the holes in the housing is fed to the sprayer, which consists of a screen and an adjustment bar 5, which has the ability to move in the horizontal plane with a screw. Passing through the gap and walls along the screen, the cooler enters the surface of the ingot.

Claims

The invention relates to the field of metallurgy, in particular to semi-metallurgy. intermittent or continuous casting of metals. A known electromagnetic crystallizer for continuous and semi-continuous casting of metals, comprising a housing, a cover, a screen of non-magnetic material and an inductor. A disadvantage of the known mold is that it does not provide a safe working voltage when casting ingots with a perimeter of more than 1.5 m. In order to provide a safe working voltage when casting ingots with a perimeter of more than 1.5 m in the proposed crystallizer, the inductor is made of individual perimeter parts, each part being connected to two current sources. FIG. Figures 1 and 2 show the proposed Cree stalli 3 at. The mold consists of body 1, screen 2 and inductor 3. The inductor consists of separate parts, along the perimeter of the common circuit with a current source, which causes the presence of not one electrical power supply, but two or more. Taking into account that the shape of the cooling jet and the exact amount of coolant supplied are of great importance for the development of ingots, the slot for directing the cooler is formed on one side by a screen, and on the other by a 4 epoxy resin, the surface of which exactly copies the surface of the screen facing it . The screen is made of stainless steel. The cooler through the holes in the housing is fed to the sprayer consisting of a screen and an adjustment bar 5, which has the ability to move in the horizontal plane with a screw. The passage through the slit and the wall across the screen, the cooler hits the surface of the ingot. Electromagnetic mold for continuous and semi-continuous casting of metals, comprising a housing, a cover, a screen and a non-magnetic material and an inductor, characterized in that, in order to ensure safe working voltage when casting ingots with a perimeter of more than 1.5 m, the inductor is made of separate parts around the perimeter, each part being connected to two current sources.
