Grouting material for blast furnace taphole maintenance and preparation method thereof
The invention discloses a grouting material for blast furnace taphole maintenance and a preparation method thereof, the grouting material adopts tar, clay, expandable graphite, bentonite, kyanite, pyrophyllite powder, silica, a plasticizer and other components to form reasonable temperature gradient gradation, and has different expansion properties corresponding to different temperature gradients. The prepared grouting material has the characteristic of good fluidity, the grouting material can be fully squeezed into a gap through on-line high-pressure grouting operation at a grouting hole in an iron notch cooling wall, the drilling power and the permeability are good in the pressing process, the grouting material can slowly creep in a small gap, the purpose of complete permeation can be achieved, and the grouting material has the characteristics of good fluidity along with continuous rising of the temperature. The expandable graphite, the kyanite, the silica and other materials are heated to continuously expand along with temperature gradient rising, dense filling of small gaps or honeycomb gaps in the iron notch area is achieved, a furnace lining around the blast furnace iron notch is effectively repaired, the maintenance performance of the blast furnace iron notch area is improved, and the service life of the blast furnace iron notch area is prolonged.
本发明公开了一种高炉铁口维护用压浆料及其制备方法，压浆料采用焦油、粘土、可膨胀石墨、膨润土、蓝晶石、叶腊石粉、硅石、增塑剂等组分形成合理的温度阶梯级配，对应不同温度梯度具有不同的膨胀性能，所制备的压浆料具有流动性好的特性，通过在铁口冷却壁上的灌浆孔处在线高压压浆作业，能够将浆料充分的挤入缝隙内部，在压入过程中钻透力、渗透性能好，能在较小的缝隙中缓慢蠕动，能够达到完全渗透的目的，随着温度不断升高，可膨胀石墨、蓝晶石、硅石等材料随温度阶梯升高受热持续膨胀，实现铁口区域细小缝隙或者蜂窝状缝隙的致密性填充，以实现高炉铁口周围炉衬得到有效的修复，提高高炉铁口区域的维护性能及其使用寿命。
