挾持してなる耐久性の優れた炉壁構造に関する。[Detailed description of the invention] The present invention involves attaching a refractory fiber block to the inner surface of non-fibrous refractories such as plastic refractories, castable refractories, and firebricks using refractory mortar, and attaching this using stud bolts. This invention relates to a furnace wall structure with excellent durability and which is efficiently clamped.
従来から工業用炉例えば鉄鋼用の加熱炉、鍛造
炉及びその他一般の加熱炉の炉壁にはセラミツク
フアイバー等の耐火繊維が取り付けられ、炉壁の
断熱強化が図られている。 BACKGROUND OF THE INVENTION Conventionally, refractory fibers such as ceramic fibers have been attached to the walls of industrial furnaces, such as steel heating furnaces, forging furnaces, and other general heating furnaces, to strengthen the heat insulation of the furnace walls.
而して、耐火繊維の断熱層は通常耐火繊維ブロ

壁面と垂直になるように配設されることも公知で
ある（特開昭52−66509又は実開昭52−159428）
が耐火繊維ブロツクが脱落し易く寿命が短い欠点
がある。 It is also known that a refractory fiber block is usually used for the heat insulating layer of refractory fibers, and the direction of the fibers in this block is arranged perpendicular to the furnace wall surface (Japanese Patent Laid-Open No. 52-66509 or (Jitsukai 52-159428)
However, the fireproof fiber blocks tend to fall off and have a short lifespan.
耐火断熱層の脱落又は剥離を防止する手段とし
て種々のアンカーボルト（例えば実開昭56−
90697、実公昭52−112534）及びその固定方法等
も提案（実開昭52−69031）されている。 Various anchor bolts (for example,
90697, Japanese Utility Model Publication No. 52-112534) and its fixing method have also been proposed (Utility Model Publication No. 52-69031).
然しながら従来の方法及び構造は、耐火繊維ブ
ロツクにボルト挿通用の孔を穿設しなければなら
ないので手間がかかる上、ブロツクの取付作業が
容易でなく能率的でない欠点がある。 However, the conventional method and structure have the disadvantage that holes for bolt insertion must be made in the refractory fiber block, which is time-consuming, and the work of installing the block is not easy or efficient.
本案は繊維ブロツクを何ら加工することなく炉
壁に強固に固着でき、剥離、脱落を確実に防止で
き信頼性の高い炉壁構造を提供するものである。 The present invention provides a highly reliable furnace wall structure in which fiber blocks can be firmly fixed to the furnace wall without any processing, and peeling and falling off can be reliably prevented.
更に、本案においては後述する如く耐火壁とブ
ロツクとの間に介装される耐火モルタル層が板状
となり全体として三層の耐火断熱層を形成し優れ
た耐久性を発揮するものである。 Furthermore, in the present invention, as will be described later, the refractory mortar layer interposed between the fireproof wall and the block is plate-shaped, forming a three-layer fireproof heat insulating layer as a whole, and exhibits excellent durability.
また本案においてはスタツドボルト自体の取付
けも極めて容易でありブロツクの取付の容易性と
相俟つて取付作業は格段に向上する利点がある。 Further, in the present invention, it is extremely easy to install the stud bolt itself, and together with the ease of installing the block, there is an advantage that the installation work is greatly improved.

耐火壁３の内面にはスタツドボルト５が後述する
間隔で植設される。 As shown in the figure, in the furnace wall structure of the present invention, a recess 3b for embedding and fixing stud bolts is provided on the inner surface 3a of a non-fibrous refractory wall 3 having an iron skin 2, and a base 5a of a stud bolt 5 is buried in the recess. At the same time, it is filled with refractory mortar 4 and fixed. As a result, stud bolts 5 are installed on the inner surface of the fireproof wall 3 at intervals to be described later.

図られるが炉の性質によつては省除してもよい。 The fiber refractory block 1 is coated with the same type of refractory mortar 4 as described above and adhered to the inner surface of the refractory wall, with the fiber direction perpendicular to the furnace wall. The blocks 1 are arranged and adhered so that their edges are closely pressed together, and at the position where the stud bolts 5 are installed, the blocks are arranged so that they are adjacent to each other as shown in FIG.
Therefore, the stud bolt always comes into contact with two or more blocks, and two or more adjacent blocks are clamped and fixed by the washer 6 attached to the head of the bolt tip. Reference numeral 7 is, for example, an alumina-silica coating material, which is used to protect the block and stud bolt or to strengthen the surface hardness, but may be omitted depending on the nature of the furnace.

ロツクとしたものである。 The block 1 used in this invention is made of fire-resistant fibers such as ceramic fibers, aluminum fibers, zirconia fibers, etc. These fire-resistant fibers are formed into a felt or blanket shape by a wet or dry method, and then It is cut into prismatic blocks of refractory fiber.

第１図に示すような方向を示すものを用いる。 The symbols a, b, and c in Figure 1 indicate the length of one side of the block, and as a specific example, a is
300 to 600 mm, b is 50 to 100 mm, and c is 50 to 100 mm. Furthermore, although the direction of the arrow indicates the fiber direction, in the present invention, one in which the fiber direction is shown in FIG. 1 is used.

ましい。 The stud bolt 5 and washer 6 are made of ceramic, usually alumina or silicon nitride. The stud bolt arrangement is 300mm x 450mm pitch for side walls and 300mm x 300mm for ceilings.
A staggered arrangement of pitches is good, but the pitch can be increased or decreased depending on the surface condition of the non-fibrous refractories on the side walls or ceiling. That is, when the surface condition of the non-fibrous refractory is extremely rough, it is desirable to increase the amount of refractory mortar applied and to narrow the stud spacing.

As shown in Figures 2 and 3, the alumina fiber blocks are laminated on the inside (heating side) of the plastic refractories on the soaking zone, side walls and ceiling of the heating zone of a heating furnace for rolling steel, and bonded with adhesive. Then, stud bolts were arranged in a staggered manner with pitches of 300 x 450 mm and 200 mm x 300 mm, respectively, and fixed with washers.

With conventional furnace walls made of 300mm x 300mm x 50mm blocks glued together with refractory mortar, about half of the ceiling fell off within a month, and a considerable amount of the side walls fell off within six months. As can be seen from this example, the furnace wall structure according to the present invention is more reliable than the furnace wall structure of the conventional method.
