High-strength argillaceous refractory mortar for hot-blast stove and preparation method of high-strength argillaceous refractory mortar
The invention discloses high-strength argillaceous refractory mortar comprises the following raw material components: clay powder, three-grade alumina raw material powder, hard clay clinker powder, silica powder and an additive. The preparation method comprises the steps of 1, putting the clay powder, the three-grade alumina raw material powder, the hard clay clinker powder and the silica powder which are weighed and proportioned into stirring equipment, and uniformly mixing; 2, adding carboxymethyl cellulose weighed according to the proportion into the stirring equipment in the step 1, and uniformly mixing; and 3, adding 25-35% by mass of instant sodium silicate into the uniformly mixed raw materials in the step 2, adding mixing water, and uniformly stirring. According to the scheme, the problem that argillaceous refractory mortar of a traditional hot-blast stove cannot be sintered to form strength in the using process is solved. By adding a burning promoter, the refractory mortar can be sintered at about 300 DEG C, has better strength in the use process, shows more excellent performance, enhances the overall bonding strength of the refractory material, and ensures the safe operation of a kiln.
一种热风炉用高强度粘土质耐火泥浆，原料成分包括粘土粉、三级矾土生料粉、硬质粘土熟料粉、硅石粉和外加剂；经过步骤一：将称重配比好的粘土粉、三级矾土生料粉、硬质粘土熟料粉和硅石粉放入搅拌设备中，混合均匀；步骤二：将按照比例称量的羧甲基纤维素加入到步骤一的搅拌设备中，混合均匀；步骤三：向混合均匀的步骤二的原料中加入质量百分比为25％～35％的速溶硅酸钠，并加入混合水，搅拌均匀；本方案改变了传统热风炉粘土质耐火泥浆在使用过程中无法烧结形成强度的问题。本发明通过加入促烧剂，在300℃左右就可以烧结，在使用过程有更好的强度，表现出更优异的性能，增加耐火材料的整体结合强度，保障窑炉安全运行。
