【発明の詳細な説明】
本発明はオイルテンパードワイヤの製造に使用
する鋼線加熱装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steel wire heating device used for manufacturing oil tempered wire.
従来は鋼線を加熱する場合に、ニクロム線等の
電気ヒータで間接的に加熱していた。この方法は
鋼線出口部を遮蔽しておけば炉からの排ガスも無
く、また鋼線出口直後の油焼入れ槽の油に引火し
て火災を起こすという危険も無いため多く用いら
れてきたが、電力費のランニングコストが高く、
又電気ヒータが劣化し、断線することがあり、ヒ
ータの取替えを要するという欠点があつた。 Conventionally, when heating a steel wire, it was indirectly heated using an electric heater such as a nichrome wire. This method has been widely used because if the exit of the steel wire is shielded, there will be no exhaust gas from the furnace, and there is no danger of the oil in the oil quenching tank immediately after the exit of the steel wire igniting and causing a fire. Running costs for electricity are high,
Another disadvantage is that the electric heater may deteriorate and break, requiring replacement of the heater.
このため、燃焼式の加熱装置も考えられている
が、燃焼加熱装置だと燃焼により生じた排ガスが
炉体各部のすきまから吹き出し、鋼線出口部を遮
蔽していてもわずかな隙間があると油焼入槽の油
に引火する危険があるという欠点があつた。 For this reason, combustion-type heating devices have been considered, but with combustion heating devices, the exhaust gas generated by combustion blows out from gaps in various parts of the furnace body, and even if the steel wire outlet is shielded, there are small gaps. The drawback was that there was a risk of the oil in the oil quenching tank catching fire.
本発明は上記欠点を除去するためになされたも
のである。 The present invention has been made to eliminate the above drawbacks.
以下、本発明の一実施例を図面に基いて説明す
る。 Hereinafter, one embodiment of the present invention will be described based on the drawings.
１は加熱炉であり、予熱部２、加熱部３および
均熱部４とにより構成されている。 Reference numeral 1 denotes a heating furnace, which is composed of a preheating section 2, a heating section 3, and a soaking section 4.
加熱部３には複数の燃焼バーナ５が予熱部２の
方向に向けて若干の角度を持つて配置されてお
り、燃焼後の排ガスの流れが排ガス出口６の方向
に流れやすくなつている。 A plurality of combustion burners 5 are arranged in the heating part 3 at a slight angle toward the preheating part 2, so that the exhaust gas after combustion can easily flow in the direction of the exhaust gas outlet 6.
予熱部２は上下の間隔を狭くして、加熱部３で
燃焼した排ガスと鋼線保護パイプ７との対流をよ
くすることにより、鋼線８の予熱効率を上げ、排
ガスの温度を下げるようにしている。 The preheating section 2 has a narrow vertical interval to improve convection between the exhaust gas burned in the heating section 3 and the steel wire protection pipe 7, thereby increasing the preheating efficiency of the steel wire 8 and lowering the temperature of the exhaust gas. ing.
均熱部４にはニクロム線９等の電気ヒータを配
置する。 An electric heater such as a nichrome wire 9 is arranged in the heat soaking section 4.
また、加熱部３と均熱部４との間にはセラミツ
クフアイバ、石綿等の断熱材からなる仕切り具１
０が上下移動可能に配置されており、使用中、加
熱部３で燃焼した排ガスが均熱部４に流入しない
ように上記仕切り具１０で以てほゞ完全に遮蔽す
る。 A partition 1 made of a heat insulating material such as ceramic fiber or asbestos is provided between the heating section 3 and the soaking section 4.
0 is arranged to be movable up and down, and during use, the partition 10 almost completely shields the exhaust gas combusted in the heating section 3 from flowing into the soaking section 4.
また、ステンレスパイプ、磁製管等の酸化防止
用の鋼線保護パイプ７は加熱炉１の下面に設けら
れたパイプ受け１１により、加熱炉１の壁面に直
接接触しないように近接配置されている。１２は
熱気遮蔽具であり、均熱部４の熱気が逃げないよ
うにする。 Further, a steel wire protection pipe 7 for preventing oxidation of stainless steel pipes, porcelain pipes, etc. is placed close to the wall surface of the heating furnace 1 by means of a pipe support 11 provided on the lower surface of the heating furnace 1. . 12 is a hot air shielding device, which prevents hot air from the soaking section 4 from escaping.
１３は油焼入れ槽であり、オーバフローした焼
入れ油が浄化装置１４を通つてポンプ１５により
循環されるよう構成されている。 Reference numeral 13 denotes an oil quenching tank, which is configured so that overflow quenching oil is circulated by a pump 15 through a purification device 14.
なお、加熱部３において使用する燃料は灯油又
はガスを用い、これらを組み合わせて使用するこ
とも可能である。 Note that the fuel used in the heating section 3 is kerosene or gas, and it is also possible to use a combination of these.
本発明は上記構成としたため、加熱に最も多く
のエネルギーを消費する加熱部において灯油又は
ガス等の安価な燃料を用いているため、約30％の
省エネルギーが計れ、しかも、予熱部を排ガスの
利用により行うため、さらに省エネルギーが計れ
る。しかも、均熱部においては電気ヒータを用い
ているが、加熱部における熱が鋼線により均熱部
に持ちこまれるため、必要最少限の電力消費でよ
く、このため電気ヒータの断線も少ない。また、
均熱部の出口は熱気遮蔽具で遮蔽されているため
焼入れ槽の油への引火の恐れも全くないものであ
る。 Since the present invention has the above configuration, cheap fuel such as kerosene or gas is used in the heating section, which consumes the most energy for heating, so approximately 30% of energy can be saved, and the preheating section uses exhaust gas. Because this is done by Moreover, although an electric heater is used in the heat soaking section, the heat in the heating section is carried into the heat soaking section by the steel wire, so that the necessary minimum power consumption is required, and therefore there are fewer disconnections of the electric heater. Also,
Since the outlet of the soaking section is shielded by a hot air shield, there is no risk of the oil in the quenching tank catching fire.
加熱部と均熱部との間は上下に移動可能な仕切
り具で仕切られているため加熱部と均熱部は間隙
なく遮蔽でき、また、補修時における鋼線保護パ
イプの出し入れが簡単にできるという優れた効果
を有するものである。 The heating section and the soaking section are separated by a partition that can be moved up and down, so the heating section and the soaking section can be shielded without any gaps, and the steel wire protection pipe can be easily inserted and removed during repairs. This has excellent effects.
