Definitions
- the invention relates to a cored wire for the introduction of additives into a bath of molten metal.
- Steels, cast irons, etc. are materials whose mechanical or other properties depend in particular on the complex composition of the material.
- the content of certain elements is adjusted to obtain the desired composition.
- This cored wire consists of a metal envelope containing the additive which it is desired to introduce into the molten bath.
- the metallic envelope was simply folded back so as to place the two edges of the shaped strip side by side.
- This process consists of mechanically stapling the two edges of the strip. It is more precisely a question of rolling the two edges together so that the edges hang on one another. This then prevents losses of the additive contained in the said strip.
- the heat of the molten metal bath causes the cored wire to explode in an area very close to the surface of the bath.
- This combustible envelope is wound in a helix around the metal sheath.
- the subject of the invention is a cored wire comprising a metallic sheath containing an additive, this sheath being characterized in that this metallic sheath is covered by an envelope 7 which, combustible without leaving any annoying residue, temporarily delays the propagation of heat to the core of the cored wire.
- FIG. 1 a section of a cored wire according to the invention
- - Figure 2 a step of preparing the cored wire
- - Figure 3 an installation using a cored wire
- FIG. 4 a section of a variant of cored wire.
- a cored wire 1 intended for the introduction of an additive into a bath 2 of molten material, such as steel, cast iron or the like.
- This molten bath is at a relatively high temperature and it is contained in a pocket 3.
- this cored wire 1 is introduced into the bath with a predetermined speed.
- this cored wire comprises a metallic sheath 5 containing an additive 6.
- This metal sheath 5 is mechanically closed, that is to say that the edges of the strip are associated with each other, for example by rolling.
- this metallic sheath is covered by an envelope 7 which, combustible without leaving annoying residues, temporarily delays the propagation of heat towards the core of the cored wire.
- An envelope may, for example, be suitable for a bath composition but not suitable for another bath composition.
- the protective casing 7 is constituted by at least one layer 7A of paper wrapped around the metal sheath.
- the cored wire explodes after one second, - with two layers, the cored wire explodes after a second and a half and
- the cored wire explodes after two seconds and two tenths.
- the layer or layers of the envelope advantageously consist of one or more helical windings of a strip of paper. These windings are for example crossed.
- An external fixing of these layers is, in an alternative embodiment, carried out by applying a layer of varnish which will obviously be devoid of water or substances reacting violently with the material constituting the bath.
- An envelope fixing layer is therefore provided, in particular when the latter is formed from several strips.
- the width of the strip is preferably adapted to the wire diameter and the conditions of use and, for example, between five and forty centimeters.
- the thickness of the protective envelope will therefore be adapted to the user's needs (temperature of the bath and material to be injected).
- FIG. 4 in particular in certain cases where the injection machine could damage the combustible envelope, above this combustible envelope 7, a metal protection 10 encloses the assembly constituted by the additive, the metallic sheath and the combustible envelope.
- This aforementioned assembly is therefore covered by a metal protection.
- This metallic protection prevents the combustible envelope from being altered during handling of the cored wire and on the other hand forms, with the metallic sheath housing the additive and the combustible envelope, a complex material delaying the melting of the assembly.
- this metal protection is constituted by a strip whose edges are stapled to form a tubular element. This is the method usually used to form the metal sheath housing the additives.
- the shape of the clip 11 has not been shown.
- the sheet of paper can be much thicker and it is laid at the same time as the metal protection.
- the edges of the thick sheet overlap.
