Definitions
- the invention relates to a method for casting thin strands, in particular made of steel, with a belt casting device in which liquid metal is fed from a metallurgical vessel via a feed device to an endless belt and a corresponding belt casting device.
- the invention has set itself the goal of providing a method with a corresponding device for casting thin strands, in which an endless belt can be produced in the desired strip thickness in a tolerated manner using simple constructional means and reliable process control.
- the invention achieves this aim by the characterizing features of the method claim 1 and the device claim 8.
- the supply quantity of the liquid metal is kept constant with respect to the discharge quantity of the finished product, that is to say the cast strip drawn off from the endless belt system.
- the flow rate of the liquid metal thread is reduced to such an extent that it occurs on the endless belt at a speed corresponding to the belt take-off speed and the liquid metal thread has a thickness in the area of impact of a desired strand thickness.
- Measuring elements for recording the level are provided for exact compliance with the level, e.g. Float or a pearl device, and to maintain the tape thickness e.g. Distance sensors which act via a measuring and control device on an actuator which controls shut-off elements for regulating the inflow amount.
- These shut-off elements can be sliders or a stopper.
- the pouring channel is designed in such a way that the first pouring channel part forms a resistance channel part.
- the second pouring channel part is designed in its mouth so that it has the same cross-sectional area as the later one
- the pouring channel has a shape in which the first channel part designed as a resistance channel is longer than the second channel part.
- a resistance element is provided in the resistance channel, which is designed as a filter and has a free area of 0.6 to 0.8 times the cross-sectional area of the pouring channel.
- the free area of this filter can consist of a bore made in a refractory plate.
- the liquid metal thread is heated in the area of the feed device.
- An advantageous embodiment of the invention is to brake the liquid metal thread.
- an eddy current brake is provided alone or in addition to the choke described above, the static magnetic field of which brakes the speed of the liquid metal thread.
- a linear motor is provided which slows down the speed of the liquid metal thread by generating a field that moves against the flow direction of the melt.
- the first pouring channel part is designed as a tube.
- This tube can be arranged in the bottom of the receptacle pointing in the vertical direction.
- the mouth of this pouring tube is connected to a second pouring channel part, which is designed as an opening funnel, the mouth of which has dimensions that correspond to the finished product.
- the second channel part can have cross-sectional areas which become smaller in the flow channel part in the flow direction of the melt.
- FIGS. 1 and 3 schematically the complete belt casting device for producing thin strands.
- Figure 2 resistance elements of the pouring channel.
- FIGS. 1 and 3 have a metallurgical vessel 21 filled with liquid metal M. which have a bottom opening 22 in the bottom. At this bottom opening 22 there is an immersion spout 23 which is immersed in a melt M which is located in a receptacle 12
- the bottom opening 22 of the metallurgical vessel 21 can be closed in FIG. 1 by a slide 25 and in FIG. 3 by a stopper 24.
- the amount of liquid metal M flowing out of the metallurgical vessel 21 is infinitely variable by actuation via an actuator 73
- the level of the liquid metal M located in the receptacle 12 is detected via the level measuring element 71, specifically in FIG. 1 by a float 74 and in FIG. 3 by a beading device 75.
- the actuator 73 and the level measuring device 71 are equipped with a measuring and control device 72 connected
- an endless belt 31 is provided below the receptacle 12, which has a driven deflection 32 and a loose deflection 33.
- the liquid metal is fed onto the upper run 34 of the endless belt 32, where it solidifies and is transported away as a finished product S.
- the feed device 11 is designed as a pouring channel, which has a first pouring channel part 14, which is designed as a resistance channel part.
- This second pouring channel part 14 is followed by a second pouring channel part 15, which has an outlet opening 16
- the thickness d w of the resistance channel part is smaller than the strand thickness d s.
- the resistance channel part has a length L 1 that is greater than the length of the second channel part L 15
- a resistance element can be provided in the first part of the casting channel, as shown in FIG. 2. lower half of the picture)
- the free area A F is made up of the sum of the holes 43 and has a size of 0.6 to 0.8 x A ⁇ (cross-sectional area of the pouring channel)
- a heating device is sketched in the lower part of the feed device 11 and an induction coil 52 in the upper part.
- the first pouring channel part 14 is tubular, which is followed by a second pouring channel part 15 of the feed device 11.
- the second pouring channel part is designed as an opening funnel which is inclined to the upper run 34 of the endless belt 31.
