本考案は分塊圧延を経て次の圧延加工に移る前
のスラブを一担保持しておくためのスラブ保持炉
に関するものである。[Detailed Description of the Invention] The present invention relates to a slab holding furnace for holding a slab after blooming and before proceeding to the next rolling process.
従来のスラブ保持炉は炉の上部開口部が開放し
たままの構造であることから、この開口部からス
ラブの熱が逃げてしまう欠点がある。 Since the conventional slab holding furnace has a structure in which the upper opening of the furnace remains open, there is a drawback that heat from the slab escapes through this opening.
このため、熱間圧延に際しての再加熱には多く
の熱量が必要となり、省エネルギーの観点からも
その改善が要望されている。又、このスラブ保持
炉の開口部にシエルターを取り付けた場合には、
スラブ移動用クレーンの邪魔になつてはならない
と共にシエルターの開閉をいちいち作業員が行う
ようなものであつてはならない。 For this reason, a large amount of heat is required for reheating during hot rolling, and improvements are desired from the viewpoint of energy saving. Also, if a shelter is installed at the opening of this slab holding furnace,
It must not get in the way of the slab moving crane, and it must not be such that workers have to open and close the shelter each time.
本考案は斯かる点に鑑みて提案されるもので、
その目的の第１はスラブから逃げる熱を抑制する
ことであり、目的の第２はクレーンの移動の邪魔
にならないようにすることであり、目的の第３は
作業員によらずにシエルターの開閉を行うことが
できるようにすることである。 This invention is proposed in view of these points,
The first purpose is to suppress the heat escaping from the slab, the second purpose is to prevent the movement of the crane from getting in the way, and the third purpose is to open and close the shelter without the need for workers. The goal is to be able to do the following.

保持炉を構成要旨として成立している。 In order to achieve the above object, the present invention is proposed in which a shelter is attached to the upper opening of a holding furnace, and the inner end of this shelter is attached to a part of a crane for moving slabs, and the shelter opens and closes as the crane moves. The main structure of this furnace is a slab holding furnace constructed as follows.

構造である。 The present invention will be described in detail below based on examples. 1 is a slab holding furnace, 2 is a slab holding chamber, and 3 is an upper opening of the slab holding furnace 1. 4 is holding furnace 1
Rails 5 laid in the longitudinal direction on both sides of the opening 3,
5, a crane that can freely move back and forth over the holding furnace 1; 6, a slab holder that can be moved up and down from the crane 4 into the holding chamber 2 through the opening 3; and a holding arm that extends downward from the bottom surface of the slab holder; 7. According to...
This structure allows the slab a to be held between both sides.

る。 Reference numeral 8 denotes guides provided on both longitudinal edges of the opening 3 of the holding furnace 1, and a number of horizontal shafts 9 are horizontally suspended between the guides 8 so as to straddle the opening 3.
is movable in the horizontal and longitudinal direction within the guide 8. Reference numeral 10 denotes a hanging member to which a shelter 11 is attached to the horizontal shaft 9 so as to cover the opening 3.
シエルター１１は第１図に示すように保持炉１

中は蛇腹状を呈し、伸縮自在の構造である。 The shelter 11 is a holding furnace 1 as shown in FIG.
is fixed to the holding furnace 1 at both ends thereof, and the inner end 1
On the 1' side, the crane 4 is attached to the fixed rod 12 of the crane 4 so as to sandwich the crane 4, and has a bellows-like structure in the middle and is expandable and retractable.
なお、シエルター１１は上記実施例のようにク
レーン４を挾む二分割の方が、クレーン４が左右

きて目的に沿うが、左右何れか一方のシエルター
のみを取り付けるようにしても構わない。 Note that it is better to divide the shelter 11 into two to sandwich the crane 4 as in the above embodiment, since it can cover the opening 3 even when the crane 4 moves in either the left or right direction. It is also possible to install only one of the shelters.
本考案は以上のように保持炉１の開口部３にシ
