Instructions: After all, strong foundry melting, sampling and analysis. According to the results of analysis, calculates the quantity of iron. For aluminum temperature to 750 ± 5 (c), opens the scum, liquid aluminium surface evenly into aluminum and iron welding pool (if need to join manganese, copper agent, can add). For 20-30 minutes, then again five minutes, stirring strongly for 5-10 minutes, sampling and analysis, after turn down. Correct control temperature, time and add mix for time and stir evenly is whether the key to improve recovery. Packing: 500g/block, 20kg/box. Deposit a cool and dry place, keep away from moisture. Shelf life: six months.
