摘要： A method and a device for continuous or semi-continuous casting of metal, where hot melt is supplied to a cooled continuous casting mold and the melt is cooled and formed to a at least partly solidified strand as it passes through the mold. An inductive coil is arranged at the top end of the mold to, when supplied with an alternating electric high frequency current, generate a high frequency magnetic field to act upon the melt in the mold, whereby heat is developed in the melt and compressive forces acting to separate the melt from the mold wall are generated. The coil is supplied with the high frequency current from a power supply unit with current control means to supply an alternating electric high frequency current having a base frequency of 50 Hz or more to the inductive coil. The current control means comprises modulation means for modulating and controlling the supplied current is controlled in a pulsed, amplitude modulated manner with an amplitude modulated modulation frequency of 10 Hz or less, whereby essentially full amplitude of the amplitude modulated current is achieved within a rise time corresponding to 1 cycle of the base frequency or less at the start of a pulse.

摘要： The invention relates to a method and device for continuous metal casting, especially for casting thin slabs of steel; in a stationary ingot mould with two wide side walls that are located opposite each other, are provided with a funnel-shaped opening in the pouring area and which converge in the direction in which the slab is removed, starting from the entrance to the ingot mould, at least with respect to part of the height of the ingot mould, in order to form a space that corresponds to the thickness of the slab to be cast. The ingot mould also comprises two narrow side strips which are jammed in between the wide sides, in addition to an immersion casting tube enabling the liquid metal to be introduced into the ingot mould. A sufficient amount of lubricant is applied to the free surface of the liquid metal in the ingot mould outside the immersion casting tube. The amount of lubricant used corresponds to the lubrication requirements of the slab at casting speeds of more than 4m/min. The surfaces of the narrow sides of the strand shell are deformed in such a way that their horizontal length is not modified by more than five times the value of the natural dimension to which the material is constrained by shrinkage forces.

To this end the invention provides for a continuous casting method comprising the following steps: a) the material is melted and a continuous strand formed from said material; b) the material strand is cooled or left to cool so that at least a part thereof has a temperature at which its structure is pasty; c) gas is introduced into that part of the material strand which has a pasty structure so as to form hollow cavities, the material strand being moved from the top towards the bottom; and d) the material is left to solidify. The invention also relates to a device for carrying out this method.

摘要： Ingress of gas such as air through the joint of a pour tube (8) and tube holder (7) of a continuous caster, or a similar interface of a slide gate valve (5, 6, 7), is prevented or inhibited by passing an inert gas into a channel (16, 21, 22, 27, 64) around the orifice and at the interface through which air is likely to enter; the gas is evenly distributed within the channel over the entire configuration of a porous refractory insert (17, 23, 24, 28, 65) which contacts the interface in the channel; the porous refractory insert assures even distribution of the gas to the desired location in the interface, thus providing a positive pressure of inert gas to inhibit the entry of ambient gas.
