Slag-corrosion-resistant high-strength furnace-melting brick for gasification melting furnace and preparation method of furnace-melting brick
The invention discloses a slag-corrosion-resistant high-strength furnace-melting brick for a gasification melting furnace and a preparation method of the furnace-melting brick. The furnace-melting brick is composed of flint clay, coagulated stone, andalusite, magnesium-rich spinel, siliceous shale, gibbsite, water-washed kaolin, alpha-Al2O3 micro powder, zinc oxide, nano carbon black, titanium dioxide, yttrium oxalate, a sintering aid, a composite water reducing agent, a binding agent and purified water. The preparation method comprises the steps: pretreatment: crushing and mixing the raw materials respectively; pressing and forming: putting the pretreated material into a brick making machine mold, pressing into a wet blank, and curing; and roasting: roasting the wet blank in a tunnel roasting kiln to obtain a finished product of the high-strength furnace-melting brick. The process is reasonable in design, and the high-strength furnace-melting brick prepared through the method has high slag corrosion resistance and structural strength and is suitable for large-scale popularization.
本发明公开了一种抗渣侵蚀的气化熔融炉用高强度炉熔砖及其制备方法，炉熔砖组成成分包括焦宝石、凝石、红柱石、富镁尖晶石、硅质页岩、三水铝石、水洗高岭土、α‑Al2O3微粉、氧化锌、纳米炭黑、二氧化钛、草酸钇、助烧剂、复合减水剂、结合剂和纯净水；制备方法包括预处理：分别将上述原料进行粉碎、混合处理；压制成型：将预处理后的物料置于制砖机模具中压制成湿坯，并进行养护；焙烧：将所述湿坯在隧道焙烧窑中焙烧处理，即得高强度炉熔砖成品；本发明工艺设计合理，通过本发明制备的高强度炉熔砖具有较强的抗渣侵蚀性能以及结构强度，适宜大量推广。
