Abstract

PROBLEM TO BE SOLVED: To make it possible to easily adjust the height of a partition wall by forming a refractory block for constituting the partition wall vertically movable in a furnace lateral direction as a ceramic fiber longitudinally long refractory block, bringing the side into contact with the side of the adjacent heat resistant block, and slidably providing it vertically in a predetermined range. SOLUTION: A ceramic fiber longitudinally long heat resistant block 8 is installed via an opening provided by cutting out the partition wall installing position of the ceiling shell 7 of an industrial furnace for heat-treating steel material in a rectangular shape in the furnace lateral direction to form a movable partition wall. Both sides 10, 10' of the block 8 are brought into vertically slidable contact with the sides of the adjacent heat insulation blocks 4, 4'. The top of the block 8 is fixed to the fixing frame 14 by using fitting 12 and mounting bolt 13 at the outside of the furnace ceiling 1, and a fixing frame 14 is vertically moved by a vertically moving mechanism 16. Thus, the height of the wall 1 can be arbitrarily adjusted within a set range to efficiently control gas flow rate.

2. Description of the Related Art Generally, industrial furnaces are classified into continuous industrial furnaces and batch industrial furnaces. Among them, in continuous heat treating furnaces for continuously heat-treating a large amount of steel materials, the inner volume increases and the furnace length increases. Becomes longer, the steel material is preheated, heated, soaked,
A partition wall may be installed in the furnace for various purposes, such as cooling and performing stepwise heat treatment, increasing the residence time of hot air in the furnace and increasing thermal efficiency. Wet partition walls and dry partition walls are available as techniques for forming this partition wall.

In the wet partition wall, an iron U-shaped pipe is fixed to the ceiling of the furnace shell to serve as a support metal for the partition wall, and an irregular refractory material is cast around it to form the partition wall. Cooling water or cooling air is sent to prevent damage to the support fitting due to heat (Japanese Utility Model Publication No. 50-5889). However, this wet partition has various drawbacks such as damage to the refractory due to heat history when the furnace is shut down, heat loss due to the cooling medium, and poor thermal response due to its large heat capacity.

Further, as a dry partition wall, a ceramic tube is hung from the ceiling of the furnace shell, a ceramic fiber blanket is pierced through it in a skewered manner, and a ceramic plate is attached to the lower part and installed, which is required in the width direction of the furnace. There is a method of arranging a number of them to form a partition wall. However,
This dry partition wall has material problems such as spalling of the ceramic plate exposed to heat, damage to the ceramic tube, buckling due to softening of the load of the ceramic fiber blanket, and attachment of the ceramic fiber blanket to the ceramic tube and ceiling. There is also a problem in terms of construction because the structure is provided with an opening to support from the outside.

As another method of the dry partition wall, there is a method of penetrating a metal rod in the furnace width direction and attaching a compressed ceramic fiber blanket (Japanese Utility Model Publication No. 60-32103). However, after setting the compressed ceramic fiber blanket in the installation work, the metal rod must be penetrated through the furnace wall, the ceramic fiber blanket, and the furnace wall in order, which makes the work difficult and in addition to the metal rod It is not practical because it has a limited length and cannot be applied to a furnace with a large furnace width.

Further, there is known a heat insulating block in which ceramic fiber blankets are continuously folded and laminated, and supporting metal fittings for the furnace body are attached to several places of the folds. In this heat insulating block, since the receiving member installed in the furnace body and the supporting metal fitting can engage with each other, the mounting work on the furnace body is easy, and the supporting metal fitting is a ceramic fiber having excellent heat insulating property. Since it is located at the deepest side (heated side) of the blanket, it has high durability (Jitsuko Sho 61-4
6396 publication). However, when this heat insulating block is used for a dry partition wall, the block height becomes the height of the partition wall, so it becomes a rectangular parallelepiped block having a height with respect to the bottom, and the tensile strength is weak and it cannot be used. However, in reality, no actual examples using this have been reported.

Since the hot air in the industrial furnace is maintained for a certain period of time, if the height of the partition wall can be adjusted to some extent, extremely efficient furnace operation becomes possible. However, the conventional partition wall structure described above, whether wet or dry,
It is fixedly installed in the furnace shell, and the height of the partition wall cannot be adjusted after installation. For example, in the case of a dry partition wall, the height of the partition wall is automatically determined by the height of the heat insulating block used, and the height cannot be adjusted unless the installed heat insulating block is replaced.

INDUSTRIAL APPLICABILITY According to the present invention, the height of the partition wall can be arbitrarily adjusted within the set range during the operation of the furnace, which was impossible with the conventional partition wall. As a result, the gas flow can be stopped or controlled, and the effect of increasing the thermal efficiency of the furnace is achieved. Moreover, as compared with the conventional dry partition wall, the construction and maintenance are extremely easy. That is, since a ceramic support material such as a ceramic tube or a ceramic plate used in a conventional dry partition wall is not required, the support material does not fall off due to cracking, etc. . Furthermore, by installing a heat-resistant ceramic sliding plate on the sliding surface of the vertically long heat-resistant block, sliding with the heat-insulating block will be smooth, the durability of the ceramic fiber blanket will be improved, and the maintenance of the movable partition wall will be easier. .
