耐火噴補(bǔ)料由具有一定顆粒級(jí)配的耐火材料、化學(xué)結(jié)合劑和外加劑組成的,用噴射施工方法對(duì)熱工設(shè)備內(nèi)襯進(jìn)行修補(bǔ)時(shí)使用的不定形耐火材料。
耐火噴補(bǔ)料按施工方法分濕法(泥漿法)噴補(bǔ)料、半干法(噴嘴混合式)噴補(bǔ)料和火焰法(熔射法)噴補(bǔ)料;按噴補(bǔ)料主材質(zhì)可分為氧化鎂質(zhì)、鎂鈣質(zhì)、鎂鉻質(zhì)、鎂碳質(zhì)、硅酸鋁質(zhì)和氧化鋁一碳化硅一碳質(zhì)噴補(bǔ)料等;按使用條件分為轉(zhuǎn)爐用噴補(bǔ)料、電爐用噴補(bǔ)料、盛鋼桶用噴補(bǔ)料、真空脫氣爐(RH、DH)用噴補(bǔ)料、岀鐵溝用噴補(bǔ)料和髙爐內(nèi)襯用噴補(bǔ)料等。
Gunning material is composed of refractory material with certain particle size distribution, chemical bond and additive. It is an amorphous refractory material used in repairing the lining of thermal equipment by spraying construction method.
According to the construction method, the fire-resistant gunning materials are divided into wet gunning materials (slurry method), semi dry gunning materials (nozzle mixing type) and flame gunning materials (fusing method); According to the main materials, gunning materials can be divided into magnesia, magnesia calcium, magnesia chromium, magnesia carbon, aluminosilicate and alumina silicon carbide carbon gunning materials; According to the service conditions, it can be divided into gunning materials for converter, electric furnace, steel barrel, vacuum degassing furnace (RH, DH), iron discharge ditch and high furnace lining.
