Self-flowing filling material suitable for converter body cavity lining making as well as preparation method and application of self-flowing filling material
The invention relates to a self-flowing filling material suitable for converter body cavity lining making and a preparation method and application thereof. The invention relates to a self-flow filling material suitable for converter body cavity lining making. The self-flow filling material comprises sintered magnesia, fused magnesia, fused spinel powder, SiO2 micro powder, explosion-proof fibers, a plasticizer carboxymethyl cellulose and a polycarboxylic acid dispersant. The filling material can realize uniform filling of the cavity of the furnace body without large-area trepanning on the furnace shell, and production can be recovered after the strength is improved through rapid sintering of the waste heat of the furnace lining.
本发明涉及适用于转炉炉体空腔造衬的自流填充料及其制备方法与应用。适用于转炉炉体空腔造衬的自流填充料，包括烧结镁砂、电熔镁砂、电熔尖晶石粉、SiO2微粉、防爆纤维、增塑剂羧甲基纤维素和聚羧酸分散剂。所述填充料不需要在炉壳上大面积开孔，即可以实现炉体空腔的均匀填充，经炉衬余温快速烧结上强度后，即可恢复生产。
