Reducing pipe maintenance method for secondary copper refining reverberatory furnace
The invention relates to a maintenance method for a reduction pipe of a secondary copper refining reverberatory furnace, which comprises the following steps: (1) normal-temperature maintenance: manufacturing a reduction steel pipe, and after refractory mortar is laid and formed on the steel pipe, integrally placing the steel pipe in a ventilated and dry position for 20-24 hours; (2) heating and curing: after the treatment in the step (1), a plurality of reduced steel pipes are put into a casting ladle oven to be heated, and the heating temperature curve is as follows: the temperature is raised to 110-130 DEG C at the temperature raising speed of 10-20 DEG C/h; then preserving heat for 3-4 hours, and removing water vapor; the temperature is increased to 400-450 DEG C at the temperature increasing speed of 25-35 DEG C/h, heating is stopped after heat preservation is conducted for 1-2 h, and the total time for heating and curing is controlled to be 20-24 h; (3) after the reduced steel pipe is maintained in the step (2), the reduced steel pipe can be put into use after being cooled to below 100 DEG C; according to the method, the secondary copper enterprise casting ladle oven is utilized, additional investment is not needed, use is easy and convenient, the operation cost is low, and the storage land of the reduction pipe is saved.
本发明涉及一种再生铜精炼反射炉还原管养护方法，包括有以下步骤：①常温养护：制作好还原钢管，待耐火泥在钢管上敷设成型后，将其整体放置于通风干燥的位置，放置时间为20h～24h；②加热养护：经过步骤①处理后，将若干根还原钢管放入浇铸包烤箱内进行加热，加热的温度曲线为：以10～20℃/h的升温速度升温到110～130℃；然后保温3～4h，排除水蒸气；再以25～35℃/h的升温速度，升温到400℃～450℃，保温1h～2h后停止加热，加热养护的总用时控制在20h～24h；③还原钢管经过步骤②养护后，待其冷却降温至100℃以下，即可投入使用；本发明的方法利用再生铜企业浇铸包烤箱，无需额外投资，使用简便，运行成本低廉，节省了还原管存放用地。
