【発明の詳細な説明】
(A) 〔産業上の利用分野〕
本発明はバンカー等の内壁面の摩耗を防止する
セラミツクライナーに関するものである。DETAILED DESCRIPTION OF THE INVENTION (A) [Field of Industrial Application] The present invention relates to a ceramic liner that prevents wear on the inner wall surface of a bunker or the like.
(B) 〔従来の技術〕
従来、石炭や鉱石等を一時貯蔵や移送するバン

摩擦による、摩耗が激しく、寿命も短いため、し
ばしば修理や取り替えを余儀なくされ、修理や取
り替えに人手や費用を要するとともに、作業能率
が低下する等の不都合があつた。(B) [Conventional technology] Conventionally, the inner walls of bunkers and transport pipes for temporarily storing and transporting coal and ore, etc. suffer from severe wear due to impact and friction from coal and ore, etc., and have a short lifespan, so they are often repaired. This resulted in inconveniences such as labor and costs being required for repairs and replacements, and a decrease in work efficiency.
また、耐摩耗対策としてバンカーや輸送管の内
壁に然摩耗性のセラミツクスを張り付ける方法等
が考えられるが、接着材による接着では強度が十
分でなく、使用中に剥離したり、特にコークスの
製造設備等では熱のため樹脂接着材は劣化が激し
く使用することができない。 In addition, as a wear-resistant measure, it is possible to attach naturally abrasive ceramics to the inner walls of bunkers and transport pipes, but adhesives do not have sufficient strength and may peel off during use, especially in the production of coke. Resin adhesives cannot be used in equipment, etc. because they deteriorate severely due to heat.
その為接合強度が強く、熱に強いセラミツクス
のメタライズ接合が考えられるが、直接バンカー
等の構築物にメタライズ接合することはできない
ので、まず金属基板にセラミツクス板をメタライ
ズ接合して複合セラミツクス板とし、この複合セ
ラミツクス板を、バンカー等の内壁にボルト止め
する等の方法が、通常用いられている。 For this reason, metallized bonding of ceramics, which have strong bonding strength and are resistant to heat, can be considered, but since it is not possible to directly metallize bond to structures such as bunkers, first metallize bond a ceramic plate to a metal substrate to make a composite ceramic plate. A commonly used method is to bolt a composite ceramic plate to the inner wall of a bunker or the like.
この場合広い面積を保護するには、ある程度広
い面積の複合セラミツクス板の使用が、作業面コ
スト面で望ましい。 In this case, in order to protect a large area, it is desirable to use a composite ceramic plate with a relatively large area from the viewpoint of working costs.
しかしセラミツクスのメタライズ接合において
は、まずセラミツクスの接合面に、例えばMo−
Mn法により、千数百度の還元雰囲気中でメタラ
イズして、金属層を形成し、これにニツケルメツ
キを施した後、金属基板に銀ろう付けするといつ
た、複雑な工程と、高温の熱処理を何度も行なう
為、セラミツクスに熱膨張差による残留応力を残
す等の不都合があつた。 However, in metallized bonding of ceramics, first, the bonding surface of the ceramics is coated with, for example, Mo-
Using the Mn method, a metal layer is formed by metallizing in a reducing atmosphere at over 1,000 degrees Celsius, which is then nickel plated and then silver brazed to a metal substrate. Because the process is repeated multiple times, there are disadvantages such as residual stress remaining in the ceramics due to the difference in thermal expansion.
また、セラミツクスに銅を直接メタライズ接合
する、然熱法に於ても、溶融変形した銅面を整形
して、金属基板へ銀ろう付けするという二度の熱
処理を必要とし、熱膨張差のあるセラミツクスと
金属基板を広面積で接合することは、熱残留応力
による、セラミツクスの割れや、セラミツクス接
合部の強度低下の心配があつた。 Furthermore, in the natural thermal method of directly metallizing bonding copper to ceramics, it is necessary to perform two heat treatments to shape the molten and deformed copper surface and to silver solder it to the metal substrate, which causes differences in thermal expansion. When joining ceramics and metal substrates over a large area, there are concerns that the ceramics may crack or the strength of the ceramic joint may decrease due to thermal residual stress.

Inside Mo
- Copper or copper alloy can be processed only once without the need for multiple heat treatments, such as forming a metal layer with Mn, plating with Ni, heat treating the Ni plating layer, and then soldering silver to the metal substrate. The aim is to obtain a composite material of ceramics and a metal substrate through heat treatment in an oxidizing atmosphere at a relatively low temperature near the melting point of It also measures the cost of joining.

However, in the present invention, the cylinders 3, which are smaller than the ceramic plate 1, are distributed over the required number of ceramic plates according to the required bonding strength and metallized bonded. In addition to reducing the influence of thermal stress on the ceramics, the bonding to the liner substrate 4 is not done by silver brazing or the like, but by caulking the copper cylinder 3, which reduces the influence of thermal stress as in the case of brazing. not be affected by.
