からのみ加熱物への加熱が行なわれる。In order to heat the material in a heating furnace, in which the material to be heated is transported through the furnace on a sliding pipe and a hearth, when the material is transported on the hearth, from the earthen wall, that is, from the hearth or hearth group. The material to be heated is heated only from the furnace part located at 2, and when transported on a sliding tube, the material is heated only from the 2 and lower needles.
上戸のバーナの範囲における加熱物および耐火構造物の
局部過熱を回避するために、約２０００ｍｍの炉空間高
さが必要である。In order to avoid local overheating of the heated material and the refractory structure in the area of the upper burner, a furnace space height of approximately 2000 mm is required.

準である。このように大きい燃焼空間は、必然的に材料
および補助装備にかなりの出費を必要とする。その上、
これらの大きい炉空間により熱損失（火炎および壁損失
）が著しく増大し、かつ炉内圧力導通が著しく困難にな
る。Therefore, a height of 3,000 to 5,000 mm within the furnace space (earthen wall height) is currently the standard for this type of furnace. Such a large combustion space necessarily requires considerable expenditure on materials and auxiliary equipment. On top of that,
These large furnace spaces significantly increase heat losses (flame and wall losses) and make pressure conduction within the furnace extremely difficult.
本発明の課題は、下戸空間から土塀空間への燃焼ガスの
自然の゛浮力を、加熱物の側面および表面への付加的熱
伝達のために利用することにある。The object of the invention is to utilize the natural buoyancy of the combustion gases from the lower door space to the earthen wall space for additional heat transfer to the sides and surfaces of the heated object.
この課題を解決するために、加熱炉が載置装置の上にお
いて、炉天井が加熱物のほぼすぐ上にありかつ大体にお
いて載置装置の下にある炉空間にしか加熱源を備えてい
ないように小さい炉空間高さを持つことが提案されてい
る。To solve this problem, the heating furnace is placed above the mounting device, and the furnace ceiling is almost directly above the object to be heated, and the heating source is only provided in the furnace space that is generally below the mounting device. It has been proposed to have a small furnace space height.
上部炉空間が、加熱物の入口範囲において付加的に上側
加熱源を備えている場合は有利であることは勿論のこと
である。この付加的な上側加熱は入口範囲だけに限られ
ており、最初から効果的な加熱を実現するためにスラブ
およびインゴットに特に適している。It is of course advantageous if the upper furnace space is additionally provided with an upper heating source in the region of the inlet of the heated material. This additional upper heating is limited to the inlet area only and is particularly suitable for slabs and ingots to achieve effective heating from the beginning.

れている。This furnace has a relatively small furnace space height in an upper furnace space 12, the so-called upper door, above the slide tube 10. The furnace ceiling 13 extends over almost the entire length of the furnace at a small distance above the heated object 11 . On the other hand, the slide pipe 10
The furnace space underneath, the so-called lower door, is constructed in a conventional manner, with side burners 15 provided on both longitudinal furnace walls.
高温燃焼ガスが下戸から上戸に流入しかつ途中で熱含量
の大部分を加熱物および炉空間の耐火ライニングに放出
する。The hot combustion gases flow from the lower door into the upper door and on the way release most of their heat content to the heating material and to the refractory lining of the furnace space.
排ガス通路１６が炉端部におけるガスの吸い出しを行な
い、この炉端部において加熱物１１が炉の中に入るので
、加熱物が、炉を通るガスに対して逆流で移動する。The exhaust gas passage 16 provides a suction of the gas at the furnace end, at which point the heated material 11 enters the furnace, so that the heated material moves in countercurrent to the gas passing through the furnace.
