【考案の詳細な説明】 〔産業上の利用分野〕 本考案は金属ストリツプの連続熱処理等に使用される
竪形マツフル炉の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of a vertical pine-furnace furnace used for continuous heat treatment of metal strips.
金属ストリツプの無酸化熱処理等に従来から使用され
ている竪形マツフル炉は、マツフルをその上端部を固定
支持して炉内に垂直に吊下げて構成されているのでマツ
フルの自重によってその上端部に最大の引張荷重が掛か
る。ところで、このマツフルはバーナ等の加熱手段によ
り高温度に繰り返し加熱され、塑性延び（クリープ）が
生じるのでクリープ現象による損壊のおそれも上端部が
最も高い。そこで、従来からマツフルを構成している板
材の肉厚を上端部を最も厚くし下方を薄くするようにし
たマツフル構造も知られている。The vertical pine-furnace furnace that has been conventionally used for non-oxidizing heat treatment of metal strips is constructed by vertically suspending the pine-furnace in the furnace with its upper end fixedly supported. Maximum tensile load is applied to. By the way, since this pineapple is repeatedly heated to a high temperature by a heating means such as a burner and plastic elongation (creep) occurs, the risk of damage due to the creep phenomenon is highest at the upper end portion. Therefore, conventionally, there is also known a pine tree structure in which the plate material forming the pine tree is made thickest at the upper end and thinned down.
しかし従来の竪形マツフル炉は、マツフルの下端部に
設けられた入口シール装置または冷却装置等の重量によ

え得るようにマツフルの耐久性を設定しなければなら

高くなるなど十分な耐久性及び経済性が達成されてなか
った。However, in the conventional vertical pineapple furnace, the tensile load due to the weight of the inlet seal device or the cooling device provided at the lower end of the pine cone is also applied to the pine cone, so the durability of the pine cone is set so that it can withstand the tensile load. Therefore, the plate thickness of the pineapple used is increased and the cost is increased, so that sufficient durability and economy are not achieved.
そこで、本考案は上端部を固定支持することでマツフ

とする。In view of the above, the present invention is directed to a vertical pine muffle furnace in which a pine cone is vertically suspended in the furnace by fixing the upper end of the pine muffle and a lower end of the pine muffler is connected to an inlet seal device and / or a cooling device. A balance weight is attached to the inlet seal device and / or the cooling device so as to bear the weight of the inlet seal device and / or the cooling device and apply a tensile load to the muffle over the entire length.
次に図面と共に本考案の実施例を説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.

てマツフル３内に導入される金属ストリツプである。FIG. 1 shows an example of a vertical pine full furnace. In the figure, 1 is a furnace body composed of a heat insulating wall, 2 is a burner provided on the furnace body wall, 3
Is a pine cone provided so as to penetrate through the furnace body, and a flange 4 is provided on the upper end of the pine cone 3.
Is supported vertically in a hanging manner. At the lower end of the pine cone 3, front chambers 7 with inlet sealing devices 6, 6 are flanged together.
It is fixed by joining 8 and 9. Then, the balance weights 10,10 are the ropes 12,12 wound around the constant pulleys 11,11.
The other ends of the ropes 12, 12 are fastened to the arms 13, 13 projecting from the front chamber 7, and the weight of the front chamber 7 and the weights of the balance weights 10, 10 are substantially The weight of the antechamber 7 is borne by the balance weights 10, 10 by making each balance. Reference numeral 14 is a metal strip introduced into the pineapple 3 through the inlet sealing devices 6,6.

A cooling device 15 for cooling the metal strip 14 by blowing cold air to the lower end of the is provided in the front chamber 7 and is connected by joining the flanges 16 and 17 to each other. In this case, the balance weight The weights of the cooling device 15 and the inlet sealing devices 6, 6 are loaded on the 10, 10.

め、そのようなことは避けなければならない。In this way, the weight of the inlet sealing device 6, 6 and / or the cooling device 15 is borne by the balance weights 10, 10 so that the pineapple 3 is not loaded with its weight, and the pineapple 3 is only subjected to its own weight. . By doing so, the tensile load applied to the pineapple 3 is greatly reduced, so that the strength required for constructing the pineapple 3 can be reduced.
For this reason, the creep resistance and durability of the plate material constituting the pineapple 3 are improved, the required plate thickness is reduced, and the weight of the pine tree itself can be reduced. Balance weight
The weight of 10,10 must bear the weight of the inlet sealing device 6,6 and / or the cooling device 15, not the weight of the muffle 3. That is, when the balance weights 10 and 10 bear the weight of the muffle 3, a compressive load is applied to the muffle 3, and buckling deformation of the muffle 3 easily occurs at a high temperature. There must be.
このように本考案の竪形マツフルは、マツフルに掛か
る重量が軽減されるのでマツフル炉の耐久性，コストを
改善できる有益な効果がある。As described above, since the vertical pineapple of the present invention reduces the weight applied to the pineapple, it has the beneficial effect of improving the durability and cost of the pineapple furnace.
