SPRAYING MATERIAL FOR REPAIR OF JOINT OF COKE OVEN
PROBLEM TO BE SOLVED: To provide a spraying material for repair of joints of a coke oven which causes less detachment of sprayed construction bodies in spraying repair of a coke oven and has good joint filling properties and adhesiveness.SOLUTION: A spraying material 2 for repair of joints of a coke oven is produced by blending siliceous refractory aggregate 3 consisting of a silica rock brick powder composed of particles consisting of 5-10 mass% of particles of particle sizes of 100-1,000 μm, 25-50 mass% of particles of particle sizes of 45-100 μm and 45-60 mass% of particles of particle sizes of smaller than 15 μm or a mixture of the silica rock brick powder and silica rock powder and a refractory raw material composed of clay externally with 1-10 mass% of sodium silicate.
【課題】コークス炉を吹付け補修する際に、吹付け施工体の剥離の少なく、良好な目地充填性と付着性を有するコークス炉目地補修用吹付け材の提供。【解決手段】粒子径が１００〜１０００μｍの粒５〜１０質量％、粒子径が４５〜１００μｍの粒子２５〜５０質量％、１５μｍ未満の粒４５〜６０質量％からなる粒子で構成された珪石れんが粉又は珪石れんが粉と珪石粉の混合物からなるシリカ質耐火骨材３及び粘土から構成される耐火原料に、珪酸ナトリウムを外掛けで１〜１０質量％配合してなるコークス炉目地補修用吹付け材２。【選択図】図１
