本考案はスライデイングノズル用プレートの改
良にかかるものである。[Detailed Description of the Invention] The present invention relates to an improvement of a plate for a sliding nozzle.

アスベストあるいはアスベストと鉄板を組み合せ

プレートの平滑性を保つために使用されている
が、鉄板は主として使用後のプレート耐火物の迅
速交換を可能とするための方式である。 A sliding nozzle device is widely used as a continuous casting device for molten steel, and is an important point for controlling the flow rate. There are still many points to be improved, such as the plate refractories used here cracking due to heat or becoming unable to slide due to expansion. Adjusting the surface pressure of the plate refractories is one of the important operations in order to smooth the sliding mechanism, but to help with this, asbestos or asbestos has traditionally been placed between the plate refractories and the metal fittings that house them. A combination of iron plates is used. Asbestos is used to maintain the smoothness of the plates, but iron plates are primarily used to allow rapid replacement of plate refractories after use.
しかしながらアスベストは耐熱性が500℃以下
であり、溶鋼などの処理によつてノズル孔に近い
部分は700℃近くなり10〜20％の収縮を起す。こ
のためアスベストの厚みに不均一な部分が生じ、
プレート耐火物の摺動面における平滑性に影響を
与えるという不都合が生じていた。 However, asbestos has a heat resistance of 500°C or less, and when treated with molten steel, the area near the nozzle hole reaches temperatures close to 700°C, causing 10 to 20% shrinkage. This causes uneven thickness of the asbestos,
There has been a problem that the smoothness of the sliding surface of the plate refractory is affected.
本考案は熱収縮することのない裏張り材として
薄い鋼板を重ねて使用するもので、特に使用時の
熱の影響を考慮して摺動面の平滑性を保たしめる
方式に関するものである。 The present invention uses stacked thin steel plates as a backing material that does not shrink due to heat, and is particularly concerned with a method for maintaining the smoothness of sliding surfaces while taking into account the effects of heat during use.
以下に本考案を図によつて説明する。 The present invention will be explained below using figures.
第１図は従来のアスベストを使用したスライデ

スベスト３が耐火物と金物の間に介在されてい
る。４はノズル孔である。 Figure 1 is a schematic longitudinal sectional front view of the fixed platen side of a sliding device using conventional asbestos.
A sliding nozzle plate refractory 2 is housed inside. Asbestos 3 is interposed between the refractory and the metal fittings in order to maintain the smoothness of the plate and to facilitate attachment and detachment from the metal fittings. 4 is a nozzle hole.
このような装置では前述したように使用時熱に
よつてアスベストが収縮し平行度に不均一を生じ
る。これはアスベストと鉄板を同時に使用したも
のでも避けることができないものである。 As mentioned above, in such a device, asbestos shrinks due to heat during use, resulting in uneven parallelism. This cannot be avoided even when asbestos and iron plates are used at the same time.
これに対し第２図は本考案のもので、プレート
耐火物と金物の間に介在させるものを厚さ１mm以
下の薄い鋼板を少なくとも３枚重ねたものとした
ものである。 On the other hand, Fig. 2 shows the present invention, in which at least three thin steel plates with a thickness of 1 mm or less are stacked to be interposed between the plate refractory and the metal fittings.
即ち、鋼板とすることによつて熱収縮でなくむ

適宜分散され、直接摺動効果に影響を与えるよう
なことはない。このような効果は厚さ１mm以下の
ものであることが必要で、同時にその枚数も少な
くとも３枚以上使用する場合でなければならな
い。 That is, by using a steel plate, thermal expansion rather than thermal contraction occurs to prevent a decrease in surface pressure. In this case, in the case of a thick steel plate, the thermal expansion exceeds the force acting simply to prevent a drop in surface pressure, reducing the sliding effect. On the other hand, by stacking three or more steel plates with a thickness of 1 mm or less, the thermal expansion force is dispersed appropriately in a direction that fills the voids in the joint surfaces of the steel plates, which directly affects the sliding effect. There's nothing to give. Such an effect requires that the thickness be 1 mm or less, and at the same time, the number of sheets must be at least 3 or more.
実施例においては0.8mmの鋼板３枚重ねたもの
で行なつたが、摺動効果にほとんど変化が表われ
なかつた。この方式は摺動盤側においても同様に
固定盤，摺動盤共行なうことが好ましいが、固定
盤側のみでも充分効果は認められた。 In the example, three 0.8 mm steel plates were used, but there was almost no change in the sliding effect. Although it is preferable to apply this method to both the fixed plate and the sliding plate on the sliding plate side as well, sufficient effects were observed on the fixed plate side only.
