【考案の詳細な説明】
本考案はウオーキングビーム式加熱炉等の鋼片
加熱炉における炉内スキツドの上面に設けられ、
処理材を直接支持するスキツドボタンに関するも
のである。[Detailed description of the invention] This invention is installed on the upper surface of the skid in the furnace in a billet heating furnace such as a walking beam heating furnace.
This relates to skid buttons that directly support treated materials.
従来、特に、高温帯で使用されるスキツドボタ
ンは、耐熱性を要求されるため、その材料として
コバルト合金等の超耐熱鋼が使用されている。 Conventionally, since skid buttons used particularly in high-temperature zones are required to have heat resistance, super heat-resistant steel such as cobalt alloy has been used as the material.
しかしながら、前記コバルト合金等の超耐熱鋼
は熱伝導率が高いのでボタン上面温度が低く、そ
のためスキツドマークが多くなるという欠点を有
し、しかも非常に高価であり、スキツドボタンの
イニシヤルコストが高くなるという欠点を有して
いた。 However, since super heat-resistant steel such as the cobalt alloy has high thermal conductivity, the top surface temperature of the button is low, which results in many skid marks. Moreover, it is very expensive, and the initial cost of the skid button is high. It had drawbacks.
ところで、スキツドボタンは、冷却水が流通す

接触部のみを超耐熱鋼とする試みもなされている
が、両耐熱鋼の接合が困難（溶接では溶接箇所が
割れる）で実用化されるに至つていないのが現状
である。 By the way, the skid button is attached to a skid pipe through which cooling water flows, and considering the fact that the lower part of the skid button is cooled and does not require much heat resistance, we used relatively inexpensive low-grade heat-resistant steel for the skid pipe side. However, attempts have been made to use super heat-resistant steel only for the upper material contact area where heat resistance is required, but it was difficult to join both heat-resistant steels (the welded part would crack during welding), so this was not put into practical use. The current situation is that this is not the case.
一方、超耐熱鋼の使用量軽減のため、その高さ
を低くすると、スキツドパイプからの冷却により
材料接触部の温度が下がり、処理材にスキツドマ
ークが発生することになり、この方法も実現不可
能である。 On the other hand, if the height of super heat-resistant steel is lowered to reduce the amount of super heat-resistant steel used, cooling from the skid pipe will lower the temperature of the material contact area, causing skid marks on the processed material, making this method impossible. be.
本考案者等は、前記欠点を解決すべく種々検討

に、断熱性に優れている（熱伝導率が小さい）点
に着目し、本考案をなすに至つたものである。 As a result of various studies to solve the above-mentioned drawbacks, the inventors of the present invention found that a fiber-reinforced alloy consisting of a metal matrix and reinforcing fibers such as alumina and boron has a particularly high heat-insulating effect compared to the heat-resistant steel conventionally used in skid buttons. The present invention was developed by paying attention to the fact that it has excellent properties (low thermal conductivity).

価な加熱炉のスキツドボタンを提供することを目
的とする。 That is, in the present invention, super heat-resistant steel on the material contact side and low-grade heat-resistant steel on the skid pipe side are integrated by casting via a layered heat-resistant fiber-reinforced alloy layer, and the heat-resistant fiber-reinforced alloy layer provides It has greater heat resistance than conventional heat-resistant steel, weakens the cooling effect of the cooling pipe, raises the top surface temperature of the button than conventional ones, reduces skid marks, and lowers the height of the button itself. An object of the present invention is to provide an inexpensive skid button for a heating furnace that makes it possible to reduce the amount of expensive super heat-resistant steel used.
つぎに、本考案を実施例である図面にしたがつ
て説明する。 Next, the present invention will be explained with reference to drawings which are embodiments.

られている。 FIG. 1 shows a first embodiment, in which 1 is a conventionally known skid pipe, and the outer periphery of a cooling pipe 2 through which cooling water flows is covered with a heat insulating material 3. 5
1 is a skid button according to the present invention, which is attached to the cooling pipe 2 by welding a stopper 4.
そして、前記スキツドボタン５は中間に耐熱性
繊維強化合金７を介在させてある。その製造方法
の一例を第３図について説明する。 The skid button 5 has a heat-resistant fiber-reinforced alloy 7 interposed therebetween. An example of the manufacturing method will be explained with reference to FIG.

される。 The figure shows a rigid centrifugal casting machine, in which a heat-resistant fiber material 6 is inserted and attached to a holding groove 12 provided on the inner surface of a band portion 11 that closes both ends of a mold 10 of approximately the same shape as a button, and is held in a predetermined shape. In addition, super heat-resistant steel 8
A molten metal is injected from the injection port 13 and the mold 10 is rotated. As a result, the molten metal is injected under pressure through the lattices or fibers of the heat-resistant fiber material 6 by centrifugal force.

所定形状のスキツドボタン５とするものである。 Next, a cast body having a heat-resistant fiber-reinforced alloy layer 7 is obtained by injecting a molten metal of low-grade heat-resistant steel 9. By cutting and removing the surface of this cast body, a skid button 5 having a predetermined shape is obtained.

る。 The heat-resistant fibers used include carbon-based fibers,
In addition to silicon carbide, boron, and alumina, alumina, boron oxide, and silica (Al 2 O 3 : 62, B 2 O 3 :
14, SiO 2 :24wet%) 3-element fibers are knitted. In particular, the latter fiber-reinforced alloy made of ternary fibers is particularly excellent in terms of heat resistance and heat insulation.

ンとすることができる。 In this way, according to the skid button 5,
A fiber-reinforced alloy layer 7 with good heat insulation is interposed in the middle, and since it is manufactured by integral casting, only the upper part that contacts the treated material is made of super heat-resistant steel 8, and the rest is made of low-grade heat-resistant steel 9, making it inexpensive as a whole. It can be a skid button.
特に、中間に断熱性の良好な繊維強化合金層７
が介在するため処理材との接触部は、冷却パイプ
２の冷却効果を受けにくいため、その温度分布

における先端ａの温度（約1150℃）を得るには、
寸法l1（20％程度）だけ低くてよく、それだけ高
価な超耐熱鋼の使用量を減少することができる。
また、逆に、同一高さとすると、接触部上面温度
をΔt1℃（50℃程度）だけ高くすることができ、
処理材へのスキツドマークの発生を、従来のもの
より低減することができる。 In particular, the fiber-reinforced alloy layer 7 with good heat insulation in the middle
Since the contact area with the treated material is not easily affected by the cooling effect of the cooling pipe 2 due to the presence of To get
The dimension l 1 (about 20%) can be lowered, and the amount of expensive super heat-resistant steel used can be reduced accordingly.
Conversely, if the height is the same, the temperature of the top surface of the contact part can be increased by Δt 1 °C (approximately 50 °C),
The occurrence of skid marks on treated materials can be reduced compared to conventional methods.
以上の説明で明らかなように、本考案の加熱炉

る。 As is clear from the above explanation, according to the skid button of the heating furnace of the present invention, the super heat-resistant steel on the material contact side and the low-grade heat-resistant steel on the skid button side are integrated by casting through a layered heat-resistant fiber-reinforced alloy layer. has been done.

クの発生を完全に防止することができる。 Therefore, compared to conventional skid buttons, the upper surface that comes into contact with the treated material has less cooling effect from the cooling pipe and can maintain a higher temperature, reducing the occurrence of skid marks, saving energy, and maintaining the same temperature. By reducing the height, the amount of expensive super heat-resistant steel used can be reduced, making it possible to create an inexpensive skid button. Further, if the height is set as in the conventional case, the temperature of the upper surface becomes higher, and the occurrence of skid marks can be completely prevented.
さらに、耐熱性繊維強化合金は層状に一体鋳造
