Galvanized steel strip packing of zinc slag recycling waste zinc ashes

Galvanized steel strip packing waste recycling of zinc ash, zinc slag in the process of hot dip galvanized homework, inevitably produce floating dust and sediment. Float ash, will directly affect the operation conditions, and thus have to scrape the ash knife to remove at any time. But the sediment production, can cause greater consumption of zinc liquid, and the sediment once formed, it can grow exponentially, this is a serious problem. So, also must be in a timely manner or on a regular basis with tao to remove slag ladle. Sometimes, due to careless operation iron slag or iron fell into the pot, can form globular zinc iron slag as the core of the snow, the snow ball zinc group can grow quickly and chunks of zinc slag formation, therefore, when have this kind of spherical zinc group is found, more to be cleared in a timely manner. Zinc slag is a kind of zinc & ndash; — Iron phase alloy solid solution, under certain conditions, also due to homework disturbance mixed and pure zinc. So, at every time of slag removal, asked the zinc liquid temperature to the first operation temperature above, make its zinc liquid and sediment separation, under temperature and then cooled to homework, make the zinc slag fully sink. Sometimes, still need such repeated several times, before being cut slag operation. Zinc content of zinc ash and zinc slag is very high, generally the zinc content in zinc ash is 79 - 86%, while the zinc content of zinc slag is higher, to as high as 90 - 95%. Therefore, from zinc ash and zinc slag can be recycled in more than 80% of the industrial pure zinc. Use of smelting method, also can be recycled more than 60% of the industrial pure zinc. So, for zinc ash and zinc dross recycling, is one of the important things. From the economic costs, the cost of every tons of recovery of zinc smelting, and only about a quarter of the purchase goods zinc. Recovery of zinc ash and zinc dross to pile up in a special set of shelter tent, best to zinc ash and zinc slag stacking respectively, so that the classification processing. In the conditional case, also can put the zinc ash and zinc slag mixture into the melting pot, and then cast ingot zinc slag. Such not only neatly stacked, and also facilitate delivery and smelting. After the slag removal, because tao slag disturbances tend to gas and other impurities in the zinc liquid, has a great influence on the quality of the galvanized. Therefore, the need to use zinc oxide to purify zinc liquid.
