本発明は、冷媒中に噴射される液状鋼の噴流の固化によ
り小径の線村を製造する為の装置の改良に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an apparatus for producing small diameter wire strips by solidification of a jet of liquid steel injected into a refrigerant.
付図に示すこの型の装置は、傷溜部2を収容する外側ケ

よっては鋼を溶融する為の装置3を有する。A device of this type, shown in the accompanying figures, has an outer casing 1 containing a flaw reservoir 2 and a device 3 for holding steel 4 in said reservoir and optionally for melting the steel.
湯溜部の底部5にダイス6が設けられていて、溶融金属

特許第2136976号)。A die 6 is provided in the bottom 5 of the sump, and a jet 7 of molten metal is passed from the sump 2 through said die 6 into a cooling chamber 8 placed in front of an orifice 9 of said die 6. sprayed inside. This is carried out by the action of gas under pressure introduced from 10 into the airtight casing 1 surrounding the sump 2. In order to obtain thin steel wires of continuous constant cross section, such as those used in metal cords for tire carcass,
Silica (S) is applied onto the liquid steel jet injected into the cooling chamber.
The applicant has discovered that it is desirable to use steels with such an unusually high silicon content that i02) is formed (French Patent No. 2,136,976).
勿論、前記の冷却チャンバの中に含有される袷煤は適当
な酸素含有量を持つ。しかし、この様に製造される鋼線
の断面はダイスの使用時間と共に増大する事が明かとな
った。Of course, the soot contained in the cooling chamber has a suitable oxygen content. However, it has become clear that the cross section of the steel wire produced in this way increases with the time the die is used.
実際に、引抜き装置のこの主要部分は有害な数種の影響
を同時に受ける。これらの影響の内、下記を挙げること

使用され、元素含有量:Si=3.5%、C=0.斑%

0%を有する純粋アルミナ(N203)ダイスは、毎時
10ミクロンのオーダの引抜き鋼線の蓬変動を生じた。In fact, this main part of the extraction device is subject to several detrimental effects simultaneously. Among these effects, the following may be mentioned: the high temperature of the molten steel, mechanical corrosion due to the molten steel flowing at speeds reaching tens of meters per second,
i, peaks, etc.) and the simultaneous corrosion action of existing oxides as well as oxides formed in the steel passing through the die (Sj02, N203, etc.). In this way, it is made at high pressure and used to draw copper at 1500°C at low speed per second, with elemental content: Si=3.5%, C=0. Spot%
, Mn=0.07%, Cr=0.8%, AI=0.01
A pure alumina (N203) die with 0% produced a fluctuation in the drawn steel wire on the order of 10 microns per hour.
初期の鋼線径は160ミクロンであったから、毎時6%
以上の直径相対変動を生じた事になる。また、特に引抜
かれる鋼が一定のケイ素含有量を有する場合、二、三の
他の力焼耐熱性酸化物の使用が推奨された。The initial steel wire diameter was 160 microns, so the rate of increase was 6% per hour.
This results in the above relative change in diameter. The use of a few other force-hardening refractory oxides was also recommended, especially when the steel to be drawn has a certain silicon content.
しかし、その場合、放射性元素を主成分とする酸化物が

工業的使用が非常に高価なものとなる。本発明の解決し
ようとする問題点は、前記の型の引抜き装置用のダイス
を製造する為、銅の腐食に対して抵抗性であると同時に
その製造が簡単で無害な耐熱性物質を探究するにある。However, in that case, oxides containing radioactive elements as a main component pose a problem. Because of the transformation of this type of oxide within the die, protective measures have to be used, making the industrial use of this type of oxide very expensive. The problem to be solved by the present invention is to find a heat-resistant material that is resistant to the corrosion of copper and at the same time easy to manufacture and harmless for manufacturing dies for drawing machines of the type mentioned above. It is in.

る。The invention therefore provides that, in installations for the pressure drawing of molten steel of the type considered, mainly zirconium oxide (Z 2
), which, although known, contain small amounts of rare metal oxides, especially yttrium oxide (Y203), and generally contain 5-12 oxides in zirconium oxide. It contains mol% of Y203.

イットリウム(Y203)はこの観点から特に適当であ
る。In fact, zirconium oxide, upon heating and cooling within a certain temperature range, undergoes a change in the crystal lattice, resulting in internal stresses and cracking or destruction of the component. As the stabilizer, it is necessary to select an oxide that has little or no reaction with the metal elements or metal oxides contained in the steel.
For this reason, especially in the case of silicon steels containing silica, lime (C
a○) is inappropriate for this purpose. The same applies to a few rare element oxides. In general, the use of all oxides that have the potential to react with silica to produce silicates with excessively low melting points should be avoided. Yttrium oxide (Y203) is particularly suitable from this point of view.

It was 190 micrometers for a drawing speed of 0 w/sec. Powder with an average diameter of 2.2 micrometers was prepared by adding 6 mol % of yttrium oxide to the zirconium oxide used (6 mol of yttrium oxide to 94 mol of zirconium oxide) at a low temperature.

This behavior may be due to the fact that the zirconium oxide does not react at all with the silicate, or that it reacts with it to form a heat-resistant solid product (zirconium silicate or zircon) at the operating temperatures during the pultrusion process. It seems that it depends.
