Definitions
- the invention relates to an installation for the continuous casting of metals. More particularly, the invention relates to a method for balancing a flow of liquid steel in an ingot mold. According to another of its aspects, the invention relates to a system for continuously casting liquid steel.
- the method further comprises the following steps:
- the relative movement between the nozzle and the ingot mold is effected by angular displacement of the nozzle along the longitudinal axis of the ingot mold. It is also possible to combine the two movements (linear and angular).
- the flow adjustment is thus achieved by a simple operation to implement.
- a system for continuously casting liquid steel from a distributor to a continuous casting mold comprising:
- transceiver designed to send light into the optical fiber and receive light reflected and / or transmitted by the optical fiber
- FIG. 1 is an overview of a continuous metal casting installation allowing the implementation of a process for balancing a flow of liquid steel in an ingot mold according to the invention
- Figures 2a and 2b are diagrams illustrating the operation of the installation of Figure 1,
- Figure 3 is a sectional view of the mold of the installation of Figure 1,
- FIG. 4 is a perspective view of a plate of the mold of Figure 3
- Figure 7 is a view on a larger scale of the installation of Figure 1 illustrating the implementation of the method to balance the flow of liquid steel in the mold.
- FIG. 1 shows an installation for the continuous casting of metals 2. It has a conventional configuration, so that most of its constituent elements will be presented only briefly.
- the nozzle 11 opens into an upper opening of an ingot mold 12.
- This is a bottomless mold having a casting axis which is vertical.
- the mold 12 will be described in more detail below.
- the installation 2 comprises cooling devices 14 positioned on an external surface of the mold 12. These are liquid-type cooling devices. For this purpose, they include conduits in which a refrigerant fluid, for example water, flows.
- the refrigerant fluid absorbs the heat from the liquid metal in the mold 12 in order to cool and solidify it.
- the metal solidifies in the form of a slab having a solidified outer surface 18 enclosing a liquid core 20.
- the installation 2 comprises a roller guide 16 located downstream of the mold 12.
- the guide 16 is used to guide the slab, an outer surface 18 of which is solidified, out of the mold 12.
- the slab gradually solidifies as it moves in the guide 16. In other words, the further away from the mold 12, the more the solidified outer surface 18 of the slab increases in volume and the more the core. liquid of the slab decreases in volume.
- each optical fiber 28 comprises an optical cladding 30 as well as a core 32 surrounded by the optical cladding 30.
- the optical fiber 28 comprises in its core 32 several Bragg filters 34.
- the optical fiber 28 comprises at least ten Bragg filters 10 per meter, preferably at least twenty Bragg filters per meter, preferably at least thirty Bragg filters per meter, and even more so. preferred at least forty Bragg filters per meter.
- Bragg filters 34 are filters which make it possible to reflect light over a range of wavelength centered on a predetermined value, called the reflected wavelength, adjustable by the constructor of the filter. This predetermined value is also a function in particular of the temperature at which the filter is located, so that we can write for each filter:
- an adjustment system designed to adjust the flow of steel in the mold 12 as a function of a control signal emitted by the processor.
- the transceiver sends light into the optical fiber 28 and the temperature is measured. of the wall of the mold 12 by virtue of the light reflected and / or transmitted by the optical fiber 28.
- the thermal characteristics of the steel present in the mold 12 are analyzed.
