High-chromium repairing material for gasification furnace and preparation method of high-chromium repairing material
The invention provides a high-chromium repairing material for a gasification furnace. The high-chromium repairing material comprises the following components in parts by mass: 69-90 parts of an electric smelting chromium oxide material with the particle size of 5-0 mm; wherein the content of the electric smelting chromic oxide material with the particle size of 200-325 meshes is 10-20%; 4-12 parts of an alumina micro powder material with a particle size of 1-5 [mu] m; 4-12 parts of chromium oxide green; 1-5 parts of a zirconium material with a particle size of less than 325 meshes; 0.1 to 3 parts of organic fiber; 1-5 parts of a binding agent; and 1-5 parts of an adhesive. The high-chromium repairing material provided by the invention has the advantages of higher fire resistance, high bonding strength after curing, scouring resistance and corrosion resistance at high temperature, is suitable for repairing local refractory brick mortar joints and obvious spalling parts in the gasification furnace, can prolong the service life of the whole high-chromium refractory brick, and ensures the normal operation of the gasification furnace.
本发明提出一种一种气化炉用高铬修补料，所述的高铬修补料其组分及组分的质量配比为：粒度5～0mm的电熔氧化铬材料：69～90；其中，粒度200～325目的电熔氧化铬材料为10～20；粒度为1～5μm的氧化铝微粉材料：4～12；氧化铬绿：4～12；粒度小于325目的锆质材料：1～5；有机纤维：0.1～3；结合剂：1～5；粘接剂：1～5。本发明提出的高铬修补料，具有较高的耐火性能，固化后粘接强度高，在高温下耐冲刷、腐蚀，适用于气化炉内局部耐火砖灰缝及剥落明显处的修补，可提高整体高铬耐火砖的使用寿命，保障气化炉正常运行。
