We can fully provide all the materials and accessories used in the production of aluminum ingot production and aluminum rod, including aluminum melting furnace equipment, launder, filter box, online degassing equipment, hot top casting, aluminum ingot casting production line, stacking ingot robot, dust removal equipment, ash stir-frying machine, ball mill, etc., out of the casting industry, the post-processing link of aluminum rod - aluminum profile extrusion, we can also provide products. Aluminum extruder, single rod heating furnace or multi-rod heating furnace, mold heating furnace, mold nitriding furnace, hydraulic oil cooler, cold bed, straightening machine, traction machine, online quenching, aging furnace, air compressor and other equipment, as well as graphite plate, mold, high temperature drum, ring belt, felt sleeve and other consumable materials. Hollow Aluminum Extrusions, Extrusion Die Manufacturers, Vacuum Nitriding Furnace, Aluminum casting process: The recycled aluminum scrap is to be heated and melted in an aluminum melting furnace,add with pure aluminum ingot, with refining flux and dross flux, the impurities will be removed, Then silicon and magnesium will be put into molten aluminum ,After flowing into launder and filter box,the molten aluminum finally reach the ingot casting line, with stacking robot, aluminum ingot will be stacked and packaging. While aluminium billet is another casting equipment, molten aluminum flows into Hot top casting plate, after cooling and Lifting and lowering of pallets, the billet will be made under the plate, then aluminum billet is hoisted out by the crane and enters the homogenization furnace, finally cut by saw.

1.To determine the concentration of FL-01 and keep it within the range of operating condition,replenish in time.

2.It is better that the aluminum profiles should be rinsing once before the brightening process for avoiding too much aluminum debris and impurities be taken in, which will influence, degreasing effect and increase the consumption of Low Temperature Polishing Additive.

3.The bath should be cleaned regularly during production because there were some insoluble substances like mechanical sundries and dust.

Low Temperature Polishing Additive is packed with sealed plastic barrel, 30kg net each.

Low temperature polishing sink–assay method
Required reagents: 1N NaOH standard solution ②1% phenolphthalein indicator ③ Potassium

①Accurately pipette 20mL of the bath solution into a 250mL conical flask, add 50mL of distilled water, then add 2 to 3 drops of 1% phenolphthalein indicator, and titrate with 1N NaOH until the solution changes from colorless to pink, which is the end point. Write down V1 without fading within 30s.

②Accurately pipette 5mL of the sink solution into a 250mL conical flask, add 50mL of distilled water, add 3g of potassium fluoride, dissolve and shake well, add 2 to 3 drops of 1% phenolphthalein indicator, and titrate with 1N NaOH until the solution is Colorless to pink is the end point, and V2 is recorded if the color does not fade within 30s .

calculate
work point (number of points) = 9.8 × V 1 × N
Free acid ((g/L)=9.8×V 2 ×N

work point	free acid	temperature
90～130	20~35g/L	18~25℃
