など工事費の増加をもたらす。Conventional technology The conventional stave installation method is based on Utility Model Application No. 51-157508.
The schematic diagram is shown in Figure 1. First, install the mounting seat 3 on the stave 1, attach the mounting seat 3 to the blast furnace shell 2, and then attach the stave mounting bolt 8.
The stave 1 is fixed by a nut 7. However, the manufacturing error of stave 1 and the blast furnace shell 2
Due to on-site welding deformation, etc., a step occurs on the inner surface of the furnace of adjacent staves. When this difference in level occurs, the heat load on the bricks inside the stave furnace becomes uneven, shortening the life of the bricks. This not only shortens the life of the blast furnace, but also increases construction costs, such as cutting the bricks when laying the bricks inside the furnace that are in close contact with the stave 1.
したがつて従来はこの段差を減少させるために
第１図の如くライナー４を取付座３と高炉鉄皮２
の間に挿入しステーブ１と高炉鉄皮２の間隔を調
整していた。 Therefore, conventionally, in order to reduce this level difference, the liner 4 was attached to the mounting seat 3 and the blast furnace shell 2 as shown in Fig. 1.
The gap between the stave 1 and the blast furnace shell 2 was adjusted by inserting it between them.

縮の大きな障害となつていた。 However, in order to insert the liner 4, it is necessary to once remove the stave 1, and therefore the time required to install the stave is approximately twice as long as when the liner 4 is not inserted. Furthermore, when narrowing the distance between the stave 1 and the blast furnace shell 2, it is necessary to cut the mounting seat 3 with a grinder or the like, which has been a major obstacle to shortening the construction period.
考案の目的

構を有するステーブを提供するものである。Purpose of the invention The present invention eliminates the above-mentioned drawbacks of the conventional stave, adjusts the distance between the blast furnace shell and the stave without removing the stave, and easily eliminates the level difference on the inside surface of the furnace between adjacent staves in a short time. The purpose of the present invention is to provide a stave that has a mechanism that allows for.
考案の構成
本考案は第２，３図に示すようにステーブ１に

のマイナス溝を設ける。Structure of the invention As shown in Figs. 2 and 3, the present invention provides at least three holes in the stave 1 so that the line connecting them forms a triangle, and a nut 5 is welded to the end of the hole on the steel skin side. A bolt 6 is inserted into the nut 5, and the end of the bolt is always projected toward the steel skin side. and bolt 6
A minus groove for rotating this bolt 6 is provided at the inner side end of the furnace.

行なうものである。 When attaching the stave 1 to the blast furnace shell 2, the bolts 6 are set in advance so that predetermined dimensions can be secured. If damage occurs on the inner surface of the furnace between the stave 1 and an adjacent stave, loosen the nut 7 of the stave mounting bolt 8,
Next, the bolt 6 is rotated to adjust the dimensions, and the nut 7 is tightened again to fix the stave 1. Thereafter, a castable is press-fitted between the stave 1 and the blast furnace shell 2, and bricks are laid on the inside of the stave 1.

めステーブ製作費も減ずることができる。Effects of the invention According to the stave of the invention, it is possible to adjust the position in the radial direction of the blast furnace by freely moving the stave to the inside of the furnace and to the side of the shell without removing the stave. Since the measurement of the step and the rotation of the bolt 6 can be performed all at once from inside the furnace, the work efficiency is improved, which has a significant effect on shortening the construction period. Furthermore, since the stave mounting seat 3 is not required, the stave manufacturing cost can also be reduced.
