Definitions
- the present invention relates to a method and a device for molding ingots of ferro-alloys by casting in cooled copper shells.
- the ferro-alloys are used in the form of crushed blocks with a unit weight which can range from a few tens from grams to a few kilograms. This is the case, in particular, of alloys based on iron and silicon, used as additives, for example for the manufacture of steels quenched with silicon and as deoxidizers of steels in general.
- patent US-A-2 308 448 which serves as a basis for the preambles of independent claims 1 and 2, a device for casting metal balls is described, in a cooled ingot mold, consisting of two removable symmetrical parts.
- the footprints are supplied with liquid metal from a central channel and bypass channels.
- the disadvantage principle is that a significant proportion of the cast metal, which fills the channel and the bypass channels, must be recycled.
- the object of the present invention is therefore a process which makes it possible to mold blocks of ferro-alloys of a predetermined shape and weight, by casting in a cooled shell, of the liquid metal leaving an elaboration furnace, either directly, or through a pocket or any intermediate container, and in such a way that almost all of the cast metal is effectively recovered in the form of blocks of predetermined shape and weight.
- This process is characterized in that all the mold cavities are fed in series, and in that the temperature of the mold, the latter being made of copper, is maintained, at all points, below 200 ° C., by cooling effective, and a quick release of the cast ingots, as soon as solidification has started.
- the device may also include cooled means for introducing the liquid ferro-alloy into the inlet channel.
- the invention is particularly well suited to the production of molded blocks of ferrosilicon having a silicon content greater than 15% and preferably between 40 and 90%, the rest being iron and, where appropriate, elements of secondary additions such as AI, Ba, Ca, Mn, Ti, Zr.
- mold-mold designates the subject of the invention, it being understood that this term designates a particular mold in which the metal is introduced in the molten state and extracted in the form multiple ingots, of predetermined size, shape and weight.
- Each mold-ingot mold (1) consists of two half-elements, or “half-shells” (2) made of electrolytic copper, preferably of so-called Cu / A1 quality (designation according to French standard NF A 51 050), each half -shell being provided with a coolant cooling circuit, comprising a main inlet (3) connected to the fluid supply means, supplying, in parallel in this case, three derived circuits (4A), (4B), (4C), which collectors exit on a common exit.
- the cooling circuits are internal [channels (5) drilled in the copper block forming the half-shells], but may possibly be external [copper tubes (6), welded or brazed over their length on the external faces of the half shells].
- Each half-shell (2) further comprises means for sealingly contacting to form the mold-mold.
- the contacting can be carried out by maintaining, for example, a fixed half-shell and bringing the other together, or even by moving the two half-shells towards one another, either by a movement of guided linear translation, either by a rotational movement around a common axis forming a hinge.
- the linear translation can be guided by any known means such as guide rods (7) sliding in internal calibrated orifices (8), or by external sliding means such as grooves and slides.
- the contacting by rotation can take place around a vertical or horizontal axis. In the latter case, the release is facilitated by the fact that the ingots are detached from the mold and fall under their own weight in a receiving means.
- Each half-shell comprises the half-cavities (10) corresponding to the ingots and to the connecting channels (11, 12).
- the half-shells can be symmetrical (fig. 1, 2, 3) or asymmetrical (10B), (10A) (fig. 4 and 5).
- One of them can even be reduced to a flat counter-plate (13) or, optionally, provided with a raised imprint (14) with cooling circuit (5) which makes it possible to increase the contact surface between the cast metal and the ingot mold, therefore, the cooling rate and the rate of casting.
- each half-shell The facing bearing faces (15) of each half-shell are erected and polished so as to ensure, under the action of the jacks (9), sufficient sealing without the interposition of any seal.
- the liquid ferro-alloy is poured into the mold preferably by means of the funnel (17).
- This part can be fixed and integrated into the mold itself, or removable, and placed on the inlet orifice (18), the bearing faces also being erected and polished.
- the funnel is also provided with a cooling circuit.
- the channels and footprints located under the funnel are supplied “in fall”, the others being supplied “at source”.
- the number and size of cavities and channels are determined to ensure complete filling before the metal begins to solidify and closes the supply channels.
- FIG. 1 represents a section of an ingot mold with 2 x 3 imprints, but this arrangement is given by way of nonlimiting example, and it could as well include 2 x 2 or 2 x 4 thereof.
- a copper ingot mold Cu / 1 was produced according to the invention, comprising a fixed central block (20), provided with internal circuits (5) for water cooling and four half-shells (21), ( 22), (23), (24), movable separately (or simultaneously) under the action of the jacks (9) and each having its own cooling circuit.
- Each half-shell corresponding to six imprints (10) connected together by channels (11), (12), which are filled, by a funnel (17) of cooled copper.
- Four of these ingot molds are therefore sufficient to mold into ingots the total production of a ferrosilicon-75 furnace of 2.4 T / h (- 20 MW). After four months of continuous use, they remain in normal operating condition.
