本発明の一実施形態を図面に基づいて説明する。   An embodiment of the present invention will be described with reference to the drawings.

図1は、本発明の一実施形態を示す正面図であり、図2は、本発明の一実施形態を示す側面図である。   FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a side view showing an embodiment of the present invention.

図1、図2に示すように、この実施形態においては、連続焼鈍炉7において、炉内のラジアントチューブ4を交換する際に、連続焼鈍炉7のロール非駆動側(OP側)にフックを位置させた天井クレーン8に加えて、連続焼鈍炉7のロール駆動側(DR側)の炉上部にラジアントチューブ搬送専用のホイスト1(ホイストレール2、ホイストワイヤフック3)を設置するとともに、連続焼鈍炉7のロール駆動側(DR側)とロール非駆動側(OP側)のそれぞれの炉側部近傍に、取り外された使用済みのラジアントチューブ4および取り付ける交換用のラジアントチューブ4を収納する移動式縦置きラック5(移動用コロ6)を設置するようにしている。   As shown in FIGS. 1 and 2, in this embodiment, when the radiant tube 4 in the furnace is replaced in the continuous annealing furnace 7, a hook is attached to the roll non-drive side (OP side) of the continuous annealing furnace 7. In addition to the overhead crane 8 positioned, a hoist 1 (hoist rail 2 and hoist wire hook 3) dedicated to transporting the radiant tube is installed on the upper part of the roll drive side (DR side) of the continuous annealing furnace 7 and continuously annealed. A movable type housing the used radiant tube 4 removed and the replacement radiant tube 4 to be mounted in the vicinity of the respective furnace side portions of the roll drive side (DR side) and the roll non-drive side (OP side) of the furnace 7. A vertical rack 5 (moving roller 6) is installed.

そして、ラジアントチューブ4の交換(使用済みラジアントチューブの取り外し、交換用ラジアントチューブの取り付け)を行うに際して、ロール駆動側(DR側)に設置したラジアントチューブ搬送専用ホイスト1を用いる場合は、以下のような手順で行う。   When the radiant tube transport hoist 1 installed on the roll drive side (DR side) is used when replacing the radiant tube 4 (removing a used radiant tube, attaching a replacement radiant tube), the following is performed. Follow a simple procedure.

(1)使用済みラジアントチューブの取り外し
(S11)予め、ロール駆動側(DR側)の炉上部にホイスト1(ホイストレール2、ホイストワイヤフック3)を設置するとともに、ロール駆動側(DR側)の炉側部近傍(ホイスト1で吊り下げできる位置)に移動式縦置きラック5を設置する。
(1) Removal of used radiant tube (S11) The hoist 1 (the hoist rail 2 and the hoist wire hook 3) is installed in advance on the furnace of the roll drive side (DR side) and the roll drive side (DR side) A movable vertical rack 5 is installed in the vicinity of the furnace side (position where the hoist 1 can be hung).

(S12)ラジアントチューブ式加熱装置から取り外されて架構デッキ9に仮置きされている使用済みラジアントチューブをホイスト1によって架構デッキ9から取り出す。   (S <b> 12) The used radiant tube removed from the radiant tube heating device and temporarily placed on the frame deck 9 is taken out from the frame deck 9 by the hoist 1.

(S13)ホイスト1によって架構9から取り出した使用済みラジアントチューブ4をそのままホイスト1によって吊り下げ、空の縦置きラック5に収納する。   (S13) The used radiant tube 4 taken out from the frame 9 by the hoist 1 is suspended as it is by the hoist 1 and stored in an empty vertical rack 5.

(S14)ホイスト1と使用済みラジアントチューブ4を分離する。   (S14) The hoist 1 and the used radiant tube 4 are separated.

(2)交換用ラジアントチューブの取り付け
(S21)予め、交換用ラジアントチューブ4を移動式縦置きラック5に収納し、その移動式縦置きラック5をロール駆動側(DR側)の炉側部近傍(ホイスト1で吊り上げできる位置)に設置する。
(2) Attaching the replacement radiant tube (S21) The replacement radiant tube 4 is previously stored in the movable vertical rack 5, and the movable vertical rack 5 is located in the vicinity of the furnace side on the roll drive side (DR side). Install at the position where it can be lifted by the hoist 1.

(S22)移動式縦置きラック5に収納されている交換用ラジアントチューブ4をホイスト1によって吊り上げる。   (S22) The replacement radiant tube 4 housed in the movable vertical rack 5 is lifted by the hoist 1.

(S23)ホイスト1によって交換用ラジアントチューブ4をラジアントチューブ式加熱沿装置に取り付ける高さ位置まで引き上げたら、そのままホイスト1によって架構デッキ9へ持ち込む。   (S23) After the replacement radiant tube 4 is pulled up to the height position where it is attached to the radiant tube type heating device by the hoist 1, it is brought into the frame deck 9 as it is.

(S24)ホイスト1と交換用ラジアントチューブ4を分離する。その後、その交換用ラジアントチューブ4を使用済みラジアントチューブ4が取り外されたラジアントチューブ式加熱装置に取り付ける。   (S24) The hoist 1 and the replacement radiant tube 4 are separated. Thereafter, the replacement radiant tube 4 is attached to the radiant tube heating device from which the used radiant tube 4 is removed.

このようにして、この実施形態においては、ロール非駆動側(OP側)にフックを位置させた天井クレーン8に加えて、ロール駆動側(DR側)にラジアントチューブ搬送専用のホイスト1を設置することによって、非駆動側(OP側)とロール駆動側(DR側)のラジアントチューブ4の交換を並行して行うことができ、天井クレーンの干渉を低減して、短時間に多数のラジアントチューブの交換を行うことが可能となる。   Thus, in this embodiment, in addition to the overhead crane 8 in which the hook is positioned on the roll non-drive side (OP side), the hoist 1 dedicated to transporting the radiant tube is installed on the roll drive side (DR side). Thus, the radiant tubes 4 on the non-drive side (OP side) and the roll drive side (DR side) can be exchanged in parallel, reducing the interference of the overhead crane and reducing the number of radiant tubes in a short time. Exchange can be performed.

また、連続焼鈍炉7のロール駆動側(DR側)とロール非駆動側(OP側)のそれぞれの側部近傍に移動式縦置きラック5を設置することによって、より一層短時間に多数のラジアントチューブの交換を行うことが可能となる。   In addition, by installing the movable vertical rack 5 in the vicinity of each side of the roll drive side (DR side) and the roll non-drive side (OP side) of the continuous annealing furnace 7, a large number of radiants can be obtained in a shorter time. The tube can be exchanged.

例えば、一度に30本のラジアントチューブを交換する場合、従来は120時間かかっていたのに対して、この実施形態を適用することによって60時間で達成することが可能になった。   For example, when 30 radiant tubes are exchanged at a time, it took 120 hours in the past, but this embodiment can be applied in 60 hours.

なお、この実施形態では、ロール駆動側(DR側)にラジアントチューブ搬送専用ホイスト1を設置しているが、ロール非駆動側(OP側)にラジアントチューブ搬送専用ホイスト1を設置してもよい。また、ロール駆動側(DR側)とロール非駆動側(OP側)の両方にラジアントチューブ搬送専用ホイスト1を設置してもよい。   In this embodiment, the radiant tube transport hoist 1 is installed on the roll drive side (DR side), but the radiant tube transport hoist 1 may be installed on the roll non-drive side (OP side). Moreover, you may install the hoist 1 only for radiant tube conveyance to both a roll drive side (DR side) and a roll non-drive side (OP side).

また、このラジアントチューブ搬送専用ホイスト1を用いて、ラジアントチューブ式加熱装置の他の部品(バーナ、レキュペレータ等)や作業工具(溶接機等)の吊り上げ、吊り下げを行うこともできる。   In addition, by using the hoist 1 for conveying the radiant tube, other parts (burner, recuperator, etc.) of the radiant tube heating device and work tools (welder, etc.) can be lifted and hung.
