Anti-blocking air hole high-dispersion air brick for anode furnace copper smelting
The invention discloses an anti-blocking air hole high-dispersion air brick for anode furnace copper smelting. The air brick comprises corundum aggregate particles, aluminum oxide fine powder, aluminum oxide micro powder, an anti-erosion agent and a binding agent. The air brick is excellent in high-temperature performance, excellent in chemical stability, high in strength, good in corrosion resistance, good in volume stability, toughness and air permeability and capable of bearing the thermal shock effect in the using process without transverse fracture and stripping. Therefore, when used under the high-temperature condition, the problem of air tightness caused by fracture due to overlarge thermal shock stress generated by temperature gradient is aovided; in addition, copper is not prone to seeping, blocking is not prone to happening, and the problem that the air brick is blocked due to copper liquid seepage is effectively solved; and the air holes forming the air channel are uniformlydistributed in the whole brick body, so that the bubbles supplied to the molten copper are fine and highly-dispersed, and a better stirring effect and a better purification effect are achieved.
本发明公开了一种防堵塞气孔高分散阳极炉炼铜用透气砖，包括刚玉骨料颗粒、氧化铝细粉、氧化铝微粉、抗侵蚀剂、结合剂。本发明高温性能优良、化学稳定性优良、强度高、耐侵蚀性好，体积稳定性、韧性和透气性能好，能够承受使用过程中的热冲击作用而不横断、剥落，从根本上避免了在高温条件下使用时，因温度梯度产生过大的热冲击应力而发生断裂导致不透气的问题；不易渗铜、不易堵塞，有效解决了铜液渗透导致透气砖发生堵塞的问题；形成气体通道的气孔均匀分布在整个砖体，供入铜液的气泡细小、分散，具有更好的搅拌效果和净化效果。
