【発明の詳細な説明】 ［産業上の利用分野］ 本発明は溶融金属容器等のライニングに用いられる耐火
物部材間を挟持するための膨張吸収性耐火パッキング材
に関する。Description: TECHNICAL FIELD The present invention relates to an expandable absorbent refractory packing material for sandwiching refractory members used for lining molten metal containers and the like.
［従来の技術］ 従来、溶融金属容器等のライニングは内張り耐火物間に
耐火モルタルが使用されている。[Prior Art] Conventionally, refractory mortar has been used between lining refractories for linings such as molten metal containers.
しかし、耐火モルタルの施工は作業の手間がかかるこ
と、乾燥接着までの時間が長い。使用時に高温になるた
め、耐火物部材間の焼付きあるいは金物と耐火物部材の
焼付きを起こすための部材の一部が使用中に損傷した場
合には、損傷部材のみの取替え使用は困難である。However, the construction of refractory mortar takes time and labor, and it takes a long time to dry and bond. Since the temperature becomes high during use, if a part of the member that causes seizure between refractory members or seizure between metal and refractory member is damaged during use, it is difficult to replace and use only the damaged member. is there.
また、耐火モルタルにて接合構成した構造体の接合部の
モルタル部は、耐溶鋼・スラグ性が劣るため、しばしば
漏鋼事故を起こし問題があった。即ち、従来のモルタル
工法による接合の問題点は当業者に周知の如く次の通り
である： 施工が困難で作業性が悪い； 耐火モルタルの耐食性及び亀裂の発生により、漏鋼事
故を生じ易い； 気密性（焼結性）の良い耐火モルタルを使用している
ため、使用後にライニング面に残鋼の付着が多く、除去
作業が煩雑である。Further, since the mortar portion of the joint portion of the structure joined by the refractory mortar is inferior in molten steel resistance and slag resistance, a steel leak accident often occurs and there is a problem. That is, the problems of joining by the conventional mortar construction method are as follows as well known to those skilled in the art: difficult to construct and poor workability; corrosion resistance of fire-resistant mortar and cracks easily cause steel leakage accidents; Since refractory mortar with good airtightness (sinterability) is used, residual steel is often adhered to the lining surface after use, and removal work is complicated.
