The magnesium alloy waste must be treated by classification before smelting, and the treatment method is as follows:

(1) Clean and sorted waste can be smelted directly

(2) Clean and sorted waste, but mixed with wood inclusions and steel inclusions, the inclusion must be removed before the furnace melting;

(3) 1 and 2 grade waste with paint and oil stains, it is necessary to remove the paint and oil stains before smelting;

(4) The processing debris, chips and slag with oil and water are more difficult to deal with, and the best way is to use a special furnace to recycle and use after vaporization under a high docile vacuum;

(5) The waste placed for a long time should be picked out, dried and then put into the melting furnace melting, sampling and analysis, according to the composition of smelting to decide what

The pre-treatment of magnesium alloy waste must be stored separately according to the classification scale, or it can be stored according to the treatment method. It is best to transport and store magnesium alloy waste in dry and covered recycling drums or clean recycling bags, indicating the grade and name of the waste on the recycling drums and bags.
