Material is QT450

Operation process:

According to the model technical standard of aluminum alloy, the aluminum alloy casting factory of TV support defines the operating composition the ablation of the elements during melting, calculates the amount of each element in the recycling waste, the composition of each element in the recycling waste should be higher than the specified amount, i.e. including the ablation amount. The measurement of each element composition by pressing holding formula: k = Ko / (1-s)

In the formula, K is the composition of a certain element in the waste of k-return furnace (%); K0 is the control composition of a certain element in the desolvation (%); s is the ablation rate of a certain element (%)

According to the total weight of the recycling waste, the net weight of each element in the recycling waste, the net weight of each element in the renewal material, the net weight of each element in the total weight of the recycling waste, the net weight of each element in the recycling waste, the net weight of each element in the recycling waste the granular material is the insufficient amount of each element, the insufficient element can be filled with non-ferrous metal; the value Sum up check if it is in accordance with the regulation of seasoning ingredients.

common problem:

Strict weighing, often check weighing equipment to ensure accuracy.

Strictly control the quality of waste materials returned to the furnace, stipulate that they shall be cleaned, dry, rusty free of dirt. Wrong material is prohibited.
