Изобретение относитс к металлургии и может быть использовано при получении качественных сталей.The invention relates to metallurgy and can be used in obtaining high-quality steels.
Известен способ обработки жидкого металла , по которому металл помещают ф футерованный ковш, вращающийс относительно своей оси iXA known method of treating a liquid metal, according to which the metal is placed f lined bucket, rotating about its axis iX
Недостатком этого способа вл етс размыв футеровки ковша слоем вращающегос металла и загр знение его неметаллическими включени ми.The disadvantage of this method is the erosion of the lining of the bucket with a layer of rotating metal and contamination with its non-metallic inclusions.
Целью .изобретени вл етс создание тKofo способа обработки металла, который исключает загр знение металла материалом размываемой футеровки ковша. The purpose of the invention is to create a metal treatment method that eliminates the contamination of the metal with the material of the scoop lining.
Достигаетс это тем, что слой жидкого металла, соприкасающийс с футеровкой, вращают электромагнитным полем синхронно с вращением емкости, при этом в перио равномерного вращени емкости число оборотов электромагнитного пол одинаково с числом оборотов емкости, при разгоне скорость вращени электромагнитного пол составл ет 1,О-2,0 скорости вращени емкости , а при торможении направление вращени электромагнитного пол измен ют на противоположное и скорость его уменьшают до 0,05-О,5 скорости вращени емкости.This is achieved by the fact that a layer of liquid metal in contact with the lining rotates the electromagnetic field synchronously with the rotation of the container, while in the period of uniform rotation of the container the number of revolutions of the electromagnetic field is the same as the number of revolutions of the container when accelerating the rotation of the electromagnetic field is 1 2.0 speeds of rotation of the capacitance, and when braking, the direction of rotation of the electromagnetic field is reversed and its speed is reduced to 0.05-0, 5 the speeds of rotation of the capacitance.
При равномерном вращении емкости синхронное вращение электромагнитного пол . полностью устран ет вление скольжение сло металла, контактирующего с футеровкой . При разгоне емкости до номинальной скорости наибольшее упреждение скорости вращени емкости относительно скорости вращени металла из соображений перегруаки двигателей не превосходит двукратного. В этом случае разность между скорост ми вращени металла и емкости компенсируют за счет увеличени в два раза скорости вращени электромагнитного пол отнрсительно скорости вращени емкости.With a uniform rotation of the capacity of the synchronous rotation of the electromagnetic field. completely eliminates the phenomenon of slipping of the metal layer in contact with the lining. When the capacity is accelerated to the rated speed, the greatest advance of the speed of rotation of the capacity relative to the speed of rotation of the metal for reasons of engine overdrive does not exceed twice. In this case, the difference between the rotational speeds of the metal and the capacitance is compensated by doubling the rotational speed of the electromagnetic field relative to the rotational speed of the capacitance.
Скорость вращени электромагнитного пол предельно приближаетс к скорости вращени емкости в случае чрезвычайно медленного набора скорости. В этом случае скорость вращени электромагнитного пол равна 1,О-1,1 скорости вращени ецкости не приводит к влению скольжени The speed of rotation of the electromagnetic field is extremely close to the speed of rotation of the capacitance in the case of extremely slow set speed. In this case, the rotational speed of the electromagnetic field is 1, O-1.1 the speed of rotation of the elasticity does not lead to a slip phenomenon.
