この考案は大型の加熱炉において、被加熱物を載置する
台車上に設置した耐火炉材の側面周囲を受止めるための
受止め装置に係る。[Detailed Description of the Invention] This invention relates to a catching device for catching the periphery of a side surface of a refractory furnace material installed on a cart on which an object to be heated is placed in a large heating furnace.
従来この種の加熱炉台車の炉材周囲の受止め装置として
は、第4図に示すように、台車A上に設置した炉材Bの
周囲に断面T字状とした受止め板Cを台車周囲に固設し
、この受止め板Cの垂直部によって炉材Bの側面を受止
めていた。Conventionally, as a receiving device around the furnace material of this type of heating furnace cart, as shown in FIG. It was fixedly installed around the periphery, and the side surface of the furnace material B was received by the vertical part of this receiving plate C.
しかしながらこのような受止め構造では、炉内が高温(
約1300℃)のため炉材Bの熱膨張による横方向の応
力に耐えられず、終には垂直部が図の鎖線の如く外方に
歪曲し炉材Bの周囲が破損脱落したり、あるいは台車A
の出入に際しこの垂直部が炉の側壁りに接触して台車の
出入を困難とする等の不都合を生じ、この補修には多額
の経費と日数を要していた。However, with this type of receiving structure, the temperature inside the furnace (
(approximately 1300°C), it cannot withstand the lateral stress due to thermal expansion of furnace material B, and eventually the vertical part is distorted outward as shown by the chain line in the figure, causing the surroundings of furnace material B to break and fall off, or Trolley A
When moving in and out of the furnace, this vertical part comes into contact with the side wall of the furnace, making it difficult to move the cart in and out, causing inconveniences, and repairing this problem requires a large amount of money and time.
またこの受止め板Cを耐熱鋼として歪曲を防止すること
も考えられるが、材料費が高額となって実用的でない。It is also possible to prevent distortion by using heat-resistant steel for the receiving plate C, but this would be impractical due to the high material cost.
そこで本考案は、この受金具の形状と設置位置を改良し

ラミックバルク等の耐火性弾性材9を充填せしめる。Reference numeral 7 denotes an irregularly shaped upper refractory material fixed around the outside of the receiving metal fitting 1 arranged around the furnace material B on the trolley A, and is fixedly supported by a locking metal fitting 8 protruding from the rib 1C of the receiving metal fitting 1. forced,
The gap between the top of the receiving metal fitting 1 and the furnace material B is filled with a refractory elastic material 9 such as ceramic bulk.
10は上部耐火材7の下方において、これを支承するよ

耐火材である。Reference numeral 10 denotes an irregularly shaped lower part which is fixedly supported below the upper refractory material 7 by a locking fitting 11 protruding from the outer periphery of the underframe A' of the trolley A so as to support it. It is a fireproof material.
このように構成した本考案によれば、加熱炉内において

に爆されることもない。According to the present invention configured in this way, when heating the object placed on the trolley A in the heating furnace, the furnace material B of the trolley A expands horizontally due to the heat, and Each receiving fitting 1 is pressed, but at this time, the end face of the furnace material B rises upward as shown by the arrow along the slope 1a of the receiving fitting 1, and the lateral pressure is reduced. 1 is cooled by the air from the branch pipe 4 that is blown into its interior, and most of the outer periphery of this bracket 1 is surrounded by the furnace material B and the upper refractory material 7, so it is not directly exposed to the hot air of the furnace. It will never happen.

台車周囲の台枠自体の冷却にも役立つのでこの台枠の熱
変形も防止されるなど優れた効果を有する。As explained above, the holder of the present invention is designed so that the expanded furnace material is pushed upward by its slope, so the lateral pressure that the holder receives is extremely small, and the inside is cooled by cold air. Since it is installed so that it is surrounded by the furnace material and the upper refractory material, it is kept at a low temperature without being directly exposed to the hot air of the furnace, has low oxidation, and is prevented from being distorted, and it maintains its original shape for a long time. The area around the trolley can be easily repaired by simply replacing the upper refractory material, and there is no risk of damage to the area around the furnace material due to distortion, which is the case with conventional receiving plates. As a result, the manufacturing cost is low, and the cooling air also helps to cool the underframe itself around the bogie, which has excellent effects such as preventing thermal deformation of the underframe.
