Refractory brick for carbon roasting furnace and preparation method of refractory brick
The invention belongs to the technical field of refractory materials, and particularly relates to a refractory brick for a carbon roasting furnace and a preparation method of the refractory brick. The refractory brick for the carbon roasting furnace, provided by the invention, comprises large bauxite clinker particles, large mullite particles, medium bauxite clinker particles, additive powder, alumina powder and a binding agent, the additive powder is composed of andalusite powder, silica powder and corundum powder according to the mass ratio of (4-8): (13-17): (11-15). According to the refractory brick, the andalusite, the silica and the corundum jointly form the additive, so that the high-temperature performance of the refractory brick for the carbon roasting furnace is effectively improved; forsterite, ferric oxide and magnesium oxide are added into the formula, so that the density and bonding strength of the refractory brick for the carbon roasting furnace are effectively improved. The refractory brick for the carbon roasting furnace is low in apparent porosity, low in high-temperature creep rate, high in refractoriness under load, stable in high-temperature volume, good in thermal stability and long in service life.
本发明属于耐火材料技术领域，具体涉及一种炭素焙烧炉用耐火砖及其制备方法。本发明提供的炭素焙烧炉用耐火砖包括铝矾土熟料大颗粒、莫来石大颗粒、铝矾土熟料中颗粒、添加剂粉料、氧化铝粉料、结合剂；所述添加剂粉料由红柱石粉、硅石粉和刚玉粉按照质量比为4‑8:13‑17:11‑15组成。本发明中采用红柱石、硅石和刚玉共同组成添加剂，有效提高了炭素焙烧炉用耐火砖的高温性能；配方中加入了镁橄榄石、三氧化二铁和氧化镁，有效提高炭素焙烧炉用耐火砖的致密度和结合强度。本发明提供的炭素焙烧炉用耐火砖的显气孔率低、高温蠕变率低，荷重软化温度高，高温体积稳定，热稳定性能好，使用寿命长。
