Embodiment Construction
[0016] A kind of technology of processing ferroalloy industry industrial waste slag of present embodiment is characterized in that: comprise the following steps:
[0017] a) Put the molten waste slag into the tempered electric furnace, detect the content of each oxide in the waste slag, add silica powder when the acidity coefficient is less than 1.6, and the acidity coefficient refers to acidic oxide / basic oxide, mainly It is the content of silicon dioxide and aluminum oxide / the content of calcium oxide and magnesium oxide, and then briefly raise the temperature to 1500 °C;
[0018] b) Put it into the heat preservation electric furnace. The function of the heat preservation electric furnace is to keep the molten waste slag warm on the one hand, and to temporarily store the molten waste slag on the other hand, so that the molten waste slag can always maintain a certain liquid level, so that the molten waste slag can flow at a certain flow rate. Stable outflow, convenient for ...
