Description

本発明は、板状側壁部材、加熱ユニット、連続式加熱炉および連続式加熱炉の製造方法に関する。   The present invention relates to a plate-like side wall member, a heating unit, a continuous heating furnace, and a method for manufacturing a continuous heating furnace.

従来より、帯鋼または鋼線材、各種電子部品、電子基板等を製造するために連続式加熱炉が用いられている（例えば、特許文献１（特開２００８−２１４６７６号公報）、特許文献２（特開２００５−１４７６４９号公報）等参照）。   Conventionally, a continuous heating furnace has been used to manufacture a steel strip or steel wire, various electronic components, an electronic substrate, and the like (for example, Patent Document 1 (Japanese Patent Laid-Open No. 2008-214676), Patent Document 2 ( JP 2005-147649 A) and the like.

図１０（ａ）に正面図、図１０（ｂ）に斜視図で例示するように、通常、連続式加熱炉ｈは、固定台ｂ上に、搬入口ｉと搬出口ｏとを有する熱処理用搬送路を内部に備えた加熱炉炉本体が設けられてなるものであって、上記搬送路内において、ガス注出入口ｇから雰囲気ガスを注入または排出しつつ、搬送ローラやコンベアー等の搬送装置を用いて熱処理物を搬入口ｉから搬出口ｏに向かって搬送し、搬送路内に複数設けられた熱処理ゾーン（図１０に示す例における熱処理ゾーンｚ１〜熱処理ゾーンｚ３）において、所望の温度領域を形成して加熱処理や冷却処理が連続的に行われる。   As illustrated in a front view in FIG. 10 (a) and a perspective view in FIG. 10 (b), the continuous heating furnace h is usually for heat treatment having a carry-in port i and a carry-out port o on a fixed base b. A heating furnace main body provided with a conveyance path is provided, and a conveyance device such as a conveyance roller or a conveyor is provided in the conveyance path while injecting or discharging the atmospheric gas from the gas inlet / outlet g. In the heat treatment zone (heat treatment zone z1 to heat treatment zone z3 in the example shown in FIG. 10) provided in the conveyance path, a desired temperature region is transferred using the heat treatment product from the carry-in entrance i toward the carry-out port o. After forming, heat treatment and cooling treatment are continuously performed.

図１０に例示するように、従来の連続式加熱炉ｈにおいては、本体内部に搬送路や外部からの汚染物質の混入を抑制するために搬送路を取り囲むマッフルが設けられるとともに、加熱炉本体の外部が、金属製の天板、側板および底板を溶接しまたはボルト締めして一体に成形された外壁構造材（外側カバー）で覆われており、上記搬送路やマッフルと、外壁構造材との間に断熱材を配設することにより、断熱性を確保している。   As illustrated in FIG. 10, in the conventional continuous heating furnace h, a muffle surrounding the conveyance path is provided in the main body to suppress contamination of contaminants from the conveyance path and the outside. The exterior is covered with an outer wall structural material (outer cover) that is integrally formed by welding or bolting a metal top plate, side plate, and bottom plate. Heat insulation is ensured by arranging a heat insulating material between them.

従来、連続式加熱炉は、上記外壁構造体（外側カバー）の内部に作業員が潜り込んだ状態でマッフルや断熱材等を設置するために、施工が煩雑で施工時間が長期化するという技術課題が存在していた。
また、一般に連続式加熱炉は、大型で重量物であるために、その運搬や施工に多大な手間とコストを要していた。 Conventionally, the continuous heating furnace has a technical problem that the construction is complicated and the construction time is prolonged because the muffle or the heat insulating material is installed in the state where the worker is buried inside the outer wall structure (outer cover). Existed.
Moreover, since a continuous heating furnace is generally large and heavy, it requires a lot of labor and cost for its transportation and construction.

さらに、本発明者等が検討したところ、従来の連続式加熱炉は、継続的に使用すると、本体に歪みや破損を生じ易いことが判明した。
これは、外壁構造体（外側カバー）が一体に成形されてなるものであるのに対し、上述したように、連続式加熱炉は、内部に複数の熱処理ゾーン（温度領域）を有するものであるために複数の熱処理ゾーン間で熱分布を生じて熱伸縮の程度に差が生じる結果、熱歪みを生じるためであると考えられる。 Further, as a result of investigations by the present inventors, it has been found that the conventional continuous heating furnace is likely to be distorted or damaged when continuously used.
This is because the outer wall structure (outer cover) is integrally formed, whereas as described above, the continuous heating furnace has a plurality of heat treatment zones (temperature regions) inside. For this reason, it is considered that heat distortion is caused as a result of heat distribution between the plurality of heat treatment zones and a difference in the degree of thermal expansion and contraction.

このような状況下、本発明は、断熱性に優れるとともに短時間にかつ簡便に施工することができ、加熱炉の熱歪みを抑制し得る連続式加熱炉用の板状側壁部材を提供するとともに、当該板状側壁部材を用いた加熱ユニット、連続式加熱炉および連続式加熱炉の製造方法を提供することを目的とするものである。   Under such circumstances, the present invention provides a plate-like side wall member for a continuous heating furnace that is excellent in heat insulation and can be easily applied in a short time and can suppress thermal distortion of the heating furnace. An object of the present invention is to provide a heating unit, a continuous heating furnace, and a manufacturing method of the continuous heating furnace using the plate-like side wall member.

上記目的を達成するために、本発明者等が鋭意検討を行った結果、連続式加熱炉の側壁の一部を形成するための部材であって、板状断熱材と当該板状断熱材の外周を補強する金属製板材とを含む板状側壁部材と、当該板状側壁部材を用いた加熱ユニット、連続式加熱炉および連続式加熱炉の製造方法により、上記技術課題を解決し得ることを見出し、本知見に基づいて本発明を完成するに至った。   In order to achieve the above object, as a result of intensive studies by the present inventors, a member for forming a part of the side wall of the continuous heating furnace, the plate-shaped heat insulating material and the plate-shaped heat insulating material The above technical problem can be solved by a plate-like side wall member including a metal plate material that reinforces the outer periphery, a heating unit using the plate-like side wall member, a continuous heating furnace, and a manufacturing method of the continuous heating furnace. The present invention has been completed based on the finding and the present knowledge.

先ず、本発明の板状側壁部材について説明する。
本発明の板状側壁部材は、連続式加熱炉の側壁の一部を形成するための部材であって、板状断熱材と当該板状断熱材の外周を補強する金属製板材とを含むことを特徴とするものである。 First, the plate-like side wall member of the present invention will be described.
The plate-like side wall member of the present invention is a member for forming a part of the side wall of the continuous heating furnace, and includes a plate-like heat insulating material and a metal plate material that reinforces the outer periphery of the plate-like heat insulating material. It is characterized by.

次に、本発明の連続式加熱炉を形成するためのユニットについて説明する。
本発明の連続式加熱炉を形成するためのユニットは、少なくとも、床部材、天井部材および本発明の板状側壁部材を含み、上記床部材を敷設した両側の少なくとも一方に本発明の板状側壁部材が立設され、その上部に天井部材が懸架されることにより、内部に搬送空間が形成されてなることを特徴とするものである。 Next, a unit for forming the continuous heating furnace of the present invention will be described.
A unit for forming the continuous heating furnace of the present invention includes at least a floor member, a ceiling member, and a plate-shaped side wall member of the present invention, and the plate-shaped side wall of the present invention is provided on at least one of both sides where the floor member is laid. A member is erected, and a ceiling member is suspended above the member, whereby a conveyance space is formed inside.

図４は、本発明のユニットの形態例を示す図である。図４（ａ）に例示するように、本発明の連続式加熱炉を形成するためのユニットは、床部材３０、天井部材２０および本発明の板状側壁部材１０、１０を含み、図４（ｂ）に示すように、このユニット４０は、上記床部材３０を敷設した両側の少なくとも一方に本発明の板状側壁部材１０が立設され、その上部に天井部材２０が懸架されることにより、内部に搬送空間ｓが形成されてなるものである。   FIG. 4 is a diagram showing an example of the form of the unit of the present invention. 4A, the unit for forming the continuous heating furnace of the present invention includes a floor member 30, a ceiling member 20, and plate-like side wall members 10 and 10 of the present invention. As shown in b), the unit 40 is constructed such that the plate-like side wall member 10 of the present invention is erected on at least one of both sides where the floor member 30 is laid, and the ceiling member 20 is suspended on the upper portion thereof. A conveyance space s is formed inside.

図４に示す例においては、本発明のユニットを形成する両側壁がいずれも本発明の板状側壁部材１０により構成されているが、片方の側壁を本発明の板状側壁部材１０により構成し、他方の側壁を公知の側壁部材により構成してもよく、本発明のユニットが、連続式加熱炉の熱処理ゾーンのうち加熱処理を行う加熱ゾーンで使用されるものである場合には、他方の側壁をパネルヒーター等の内部に加熱ユニットを有する側壁部材により構成してもよい。
他方の側壁が内部に加熱ユニットを有するものであることにより、各ユニット単位もしくは併設する複数のユニット単位で内部を所望温度に加熱制御してなる加熱ゾーンを容易に形成することができる。 In the example shown in FIG. 4, both side walls forming the unit of the present invention are each constituted by the plate-like side wall member 10 of the present invention, but one side wall is constituted by the plate-like side wall member 10 of the present invention. The other side wall may be constituted by a known side wall member. When the unit of the present invention is used in a heating zone in which heat treatment is performed among heat treatment zones of a continuous heating furnace, You may comprise a side wall by the side wall member which has a heating unit in the inside of a panel heater etc.
Since the other side wall has a heating unit inside, a heating zone can be easily formed by heating the inside to a desired temperature by each unit unit or a plurality of unit units provided side by side.

本発明のユニットを構成する床部材や天井部材の材質は、所望の断熱性を発現し得るものであれば特に制限されず、上述した本発明の板状側壁部材を構成する板状断熱材と同様の素材により構成することができる。   The material of the floor member and the ceiling member constituting the unit of the present invention is not particularly limited as long as the desired heat insulating property can be expressed, and the plate-like heat insulating material constituting the plate-like side wall member of the present invention described above. A similar material can be used.

本発明のユニットが、連続式加熱炉の加熱ゾーンで使用されるものである場合、本発明のユニットを構成する床部材または天井部材は、当該床部材または天井部材の内部に加熱ユニットを有するものであることが好ましく、具体的には、パネルヒーター等であることが好ましい。
床部材または天井部材が、内部に加熱ユニットを有するものであることにより、熱処理ゾーンとして、各ユニット単位もしくは併設する複数のユニット単位で内部を所望温度に加熱制御してなる加熱ゾーンを容易に形成することができる。
また、逆に、床部材または天井部材が、上述した内部に加熱ユニットを有さないものであることにより、熱処理ゾーンとして、各ユニット単位もしくは併設する複数のユニット単位で内部を所望温度に冷却制御してなる冷却ゾーンを容易に形成することができる。 When the unit of the present invention is used in a heating zone of a continuous heating furnace, the floor member or ceiling member constituting the unit of the present invention has a heating unit inside the floor member or ceiling member. Specifically, a panel heater or the like is preferable.
As the floor member or ceiling member has a heating unit inside, a heating zone can be easily formed as a heat treatment zone by heating control to the desired temperature in each unit unit or a plurality of unit units provided side by side. can do.
On the contrary, the floor member or ceiling member does not have a heating unit in the interior, and as a heat treatment zone, the inside is controlled to a desired temperature by each unit unit or a plurality of unit units provided side by side. Thus, the cooling zone formed can be easily formed.

本発明のユニットは、例えば、図４（ａ）および図４（ｂ）に示すように、所望の設置位置に床部材３０を設置した後、その両側に本発明の板状側壁部材１０、１０を立設し、その上部に天井部材２０を懸架することにより、ユニット４０を容易に形成することができる。   For example, as shown in FIGS. 4 (a) and 4 (b), the unit of the present invention installs the floor member 30 at a desired installation position and then forms the plate-like side wall members 10 and 10 of the present invention on both sides thereof. The unit 40 can be easily formed by suspending the ceiling member 20 on the top.

上記床部材、板状側壁部材、天井部材は、適宜各種形状を有する固定金具等を使用することにより相互に連結してもよいが、必ずしも相互に連結されている必要はない。
例えば、図４（ｂ）に例示するユニット４０においては、所定位置に配置した床部材３０の両側に単に本発明の板状側壁部材１０、１０を立設し、その上部に天井部材２０を配置しているのみであって、互いに連結されていない。
このように、ユニットを構成する床部材、板状側壁部材および天井部材を互いに連結しないことにより、連続式加熱炉の内部で熱分布を生じてユニットを構成する各部材間で熱伸縮の程度に差が生じた場合であっても、熱伸縮による影響を低減して加熱炉の熱歪みを有効に抑制することができる。 The floor member, the plate-like side wall member, and the ceiling member may be connected to each other by appropriately using a fixing bracket having various shapes, but it is not always necessary to be connected to each other.
For example, in the unit 40 illustrated in FIG. 4B, the plate-like side wall members 10 and 10 of the present invention are simply erected on both sides of the floor member 30 arranged at a predetermined position, and the ceiling member 20 is arranged on the upper portion thereof. Are not connected to each other.
Thus, by not connecting the floor member, the plate-like side wall member, and the ceiling member that constitute the unit, heat distribution is generated inside the continuous heating furnace, and the degree of thermal expansion and contraction between the members constituting the unit is achieved. Even if a difference occurs, the thermal distortion of the heating furnace can be effectively suppressed by reducing the influence of thermal expansion and contraction.

本発明のユニットは、床部材、板状側壁部材および天井部材を含むものであるが、本発明のユニットが複数併設される場合には、床部材、板状側壁部材または天井部材をユニット間で共有していてもよい。
例えば、図４（ｃ）は、２つのユニット４０、４０を併設した例であって、図４（ｃ）に示す例においては、同一の天井部材２０が両ユニット間で共有されている。
このように、隣接するユニット間で床部材、板状側壁部材または天井部材を共有することにより、熱漏れの発生を抑制し、各ユニットをより簡便に施工し易くなる。 The unit of the present invention includes a floor member, a plate-like side wall member, and a ceiling member. However, when a plurality of units of the present invention are provided, the floor member, the plate-like side wall member, or the ceiling member is shared between the units. It may be.
For example, FIG. 4C is an example in which two units 40 are provided, and in the example shown in FIG. 4C, the same ceiling member 20 is shared between both units.
Thus, by sharing a floor member, a plate-like side wall member, or a ceiling member between adjacent units, the occurrence of heat leakage is suppressed and each unit can be more easily installed.

本発明のユニットは、連続式加熱炉を形成するためのものであって、ユニットを複数並設して連続式加熱炉を構成し、ユニットを構成する床部材、板状側壁部材および天井部材のサイズやユニットの使用数を調整することにより、種々のサイズを有する連続式加熱炉を短期間で簡便かつ低コストに製造することができる。   The unit of the present invention is for forming a continuous heating furnace, and a plurality of units are arranged side by side to form a continuous heating furnace. The floor member, the plate-like side wall member, and the ceiling member that constitute the unit are provided. By adjusting the size and the number of units used, continuous heating furnaces having various sizes can be manufactured easily and at low cost in a short period of time.

このため、本発明によれば、断熱性に優れるとともに短時間にかつ簡便に施工することができ、加熱炉の熱歪みを抑制し得るユニットを提供することができる。   For this reason, according to this invention, while being excellent in heat insulation, it can be constructed easily in a short time, and the unit which can suppress the thermal distortion of a heating furnace can be provided.
