The method of electromagnetic mixing of the liquid phase of a continuous-cast ingot involves the imposition of crossed electric and magnetic fields, while the floor is laid over the length of the ingot periodically with an interval of 2.0 - 2.5 A, where A is the width of the ingot. 2 Il.
Description
Изобретение относитс к металлургии , конкретнее к способам электромагнитного перемешивани жидкого металла в процессе непрерьшной разливки .The invention relates to metallurgy, and more specifically to methods of electromagnetic stirring of a liquid metal in the process of continuous casting.
Цель изобретени - расширение технологических возможностей.The purpose of the invention is the expansion of technological capabilities.
На фиг. 1 представлена схема устройства , реализующего предлагаемый способ; на фиг. 2 - сечЕние А-А на фиг. 1.FIG. 1 shows a diagram of the device that implements the proposed method; in fig. 2 - section AA in FIG. one.
На слиток 1 с жидким дром 2 с помощью электромагнита посто нного тока 3 и токоподвод щих роликов 4 накладывают скрещенные электрическое и магнитное пол . Блоки кондук- ционного электромагнитного перемешивани (КЭМП), включающие электромагнит и токоподвод щие ролики, располагают по длине слитка периодично.On the ingot 1 with the liquid core 2 by means of the electromagnet of direct current 3 and the current-carrying rollers 4 impose a crossed electric and magnetic field. Conductive electromagnetic mixing (CEMP) blocks, including an electromagnet and current-carrying rollers, are arranged along the ingot length periodically.
Пример. Отливают сл б сечением 1,7-0,24 м и осуществл ют электромагнитное перемешивание жидкой фазы слитка в зоне вторичного охлаждени . Блоки КЭМП располагают по длине слитка периодично с интервалом 3,4-4,3 м, при этом ширина магнитного пол 0,60-0,68 м. При линейной токовой нагрузке 215 кА/м, магнитной индукции 0,2 т в жидком дре слитка ширшюй 1,7м развиваетс сила Лоренца 15 кН/м, обеспечивающа перемешивание жидкой фазы слитка с максимальной скоростью 0,65 м/с.Example. The slab is cast with a cross section of 1.7-0.24 m and the electromagnetic stirring of the liquid phase of the ingot in the secondary cooling zone is carried out. CEMP blocks are arranged along an ingot length periodically with an interval of 3.4-4.3 m, with a magnetic field width of 0.60-0.68 m. With a linear current load of 215 kA / m, a magnetic induction of 0.2 tons in a liquid core An ingot of width 1.7 m develops a Lorentz force of 15 kN / m, which ensures the mixing of the liquid phase of the ingot with a maximum speed of 0.65 m / s.
Предлагаемый способ позвол ет расширить его технологические возможности и эффективно обрабатывать слитки крупного сечени .The proposed method allows to expand its technological capabilities and efficiently process ingots of a large cross section.
