The furnace body is constituted by a steel sheet casing lined with a refractory material 3, and has a built-in hearth roll for transporting the strip, a heater for heating, and the like (not shown). Further, the furnace body includes a detachable furnace lid 2 and a furnace body 1.
Divided into parts. The furnace lid 2 is divided into a plurality of parts, and is used for regular maintenance and inspection of furnace equipment such as a hearth roll and a heater for heating, and when the band 15 is broken in the furnace. The structure is such that it can be detached from the furnace main body 1 so that restoration work can be performed quickly. The furnace lid 2 has a structure in which a refractory material 4 is lined like the furnace body 1.

いうのが実態であった。In the case where the furnace lid is detachable as in the prior art, when the furnace lid is attached or detached, the seal groove of the furnace body and the seal holder of the furnace lid are pressed, or when the bolt is fastened. It is necessary to precisely match the positions of the bolt holes on the furnace body side and the furnace lid side. However, in an actual operation, a large amount of time and labor was required for the operation of attaching and detaching the furnace lid including this alignment. In other words, when attaching and detaching the furnace lid, the furnace lid is mainly lifted by the overhead crane in the factory, or when the furnace lid is mounted, the work is hung by the overhead crane, and the work is performed. The actual situation was that the operator and the crane operator, who visually checked and signaled, had to cooperate with each other and work, and it took a lot of time.

ざるを得なかった。[0006] In order to reduce the trouble of aligning the furnace lid as much as possible, the absolute position of the furnace lid is measured in advance, and the stop position of the overhead crane, that is, the hanging position of each furnace lid, is set in accordance therewith. It is also conceivable to adjust the stop position of the overhead crane using the above method.However, in the case of a horizontal furnace, since the amount of thermal expansion of the horizontal furnace body changes depending on the furnace body surface temperature at the time of attaching and detaching work, the position of each furnace lid Since the temperature changes every time depending on the furnace temperature or the furnace body surface temperature at the time of the attaching / detaching work, the position of the attaching / detaching has to be visually checked by the operator.

If this refractory material is directly placed on the floor of a temporary storage place or on a work deck, there is a possibility that the refractory material itself may be damaged such as cracks. Furthermore, it is rather rare that the furnace lid is released after the furnace temperature has completely cooled, and the temperature of the furnace is usually reduced due to oxidation of the furnace equipment in order to save maintenance and inspection time. In many cases, the refractory material of the furnace lid itself is also in a high temperature state, and therefore the refractory material surface is made of a cold concrete floor or steel plate. Putting it on a deck is likely to cause damage due to thermal shock of the refractory material, and in the case of concrete floor, the surface temperature of concrete rises due to the effect of heat storage of the refractory material, and there is also a problem of deterioration in strength and deterioration of concrete. I have to.
