玄武岩铸石技术在高炉冲渣沟中的应用

Application of Casting Basalt Technology in the Sluiceway of BF

为解决 5 #、6#高炉冲渣沟原 16Mn衬板因冲蚀、腐蚀磨损严重 ,局部翘曲变形的问题 ,采用耐蚀性及耐磨性均较好的玄武岩铸石板作为冲渣沟内衬。设计铸石板结构为防滑形并预留孔用螺栓锚固 ,增加了铸石板与底部灌浆料粘接的可靠性 ,采用 CGM自流型灌浆料施工 ,工期仅为 4天。应用 3年后检查 ,铸石板仅有微量磨损。

In order to resolve the part distortion problem of 16Mn scaleboard used in the sluiceway of No.5 and No.6 BF because of heavy erosion-corrosion wear,casting basalt scaleboard that has good properties of resisting corrosion and resisting wear was adopted.An anti-skidding lattice pattern on the back of the basalt board was designed and a hole was kept to rivet by bolt.Therefore,bonding reliability was increased between the casting basalt scaleboard and the grouting stuff,using CGM stuff to adhibit basalt scaleboard in building operation.The time limit of the project was only four days and the casting basalt scaleboard had little abrasion checked three years later.
