Tin bath bottom brick and preparation method thereof
The invention belongs to the technical field of refractory materials, and discloses a tin bath bottom brick and a preparation method thereof. The tin bath bottom brick is prepared from the following raw materials in parts by weight: 60-80 parts of silicon-aluminum clinker, 1-5 parts of pure calcium aluminate cement, 6-20 parts of high-aluminum fine powder, 2-4 parts of clay powder, 1-5 parts of silica powder, 1-3 parts of silica sol, 1-3 parts of alumina sol and 0.1-0.3 part of a water reducing agent. The tin bath bottom brick disclosed by the invention mainly has the following advantages: the tin bath bottom brick is relatively proper in volume density, relatively low in apparent porosity and relatively good in high-temperature usability (strain rate, expansion rate and thermal shock stability at high temperature); as the use of mineral substances and cement is reduced, the matrix structure of the bottom brick is changed, the noxidation degree of the tin bath bottom brick is reduced, and the service life of the tin bath bottom brick is prolonged; meanwhile, the heat conductivity coefficient is low, the heat preservation effect is good, the heat loss is reduced, the heat utilization efficiency can be remarkably improved, the industrial production energy consumption is reduced, and the purposes of energy conservation and emission reduction are achieved.
本发明属于耐火材料技术领域，公开了一种锡槽底砖及其制备方法。所述锡槽底砖由以下重量份数的原料制成：硅铝熟料60～80份、纯铝酸钙水泥1～5份、高铝细粉6～20份、粘土粉2～4份、硅微粉1～5份、硅溶胶1～3份、铝溶胶1～3份、减水剂0.1～0.3份。本发明的锡槽底砖主要具有以下优点：较适当的体积密度、较低的显气孔率、较好的高温使用性能(高温时的应变率、膨胀率、热震稳定性)；由于减少矿物质和水泥的使用，改变了底砖的基质结构，使锡槽底砖的霞石化程度降低，延长其使用寿命；同时具有较低的导热系数、保温效果好，减少热损失，能够显著提高热利用效率，减少工业生产能耗，以达到节能减排的目的。
