Q:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
Q:How does aluminum ingot be processed to aluminum coil (aluminum sheet)?
First it should be made into blank and then put on the rolling mill.
Q:How to deal with too much aluminum powder in aluminum striping?
Currently, there are bag dust-removal system and water dust-removal system. The former is very popular with enterprises because of low maintenance cost, accounting for over 90%. But the problem is the dust accumulation because the ventilation and dust removal systems are not produced in strict accordance with the standard. For example, controlling wind speed does not meet the requirement; ventilation and dust removal system does not meet the requirements of explosion-proof, including the set of pipes, series and parallel connection, the choice of dust removal system, the spark detection and extinguishing measures.
Q:Why 5052 turn black after annealing during the production of aluminum alloy?
It has been sooted.
Q:How to remove the fingerprint and glue residue on the color aluminum coil?
Try to use essential balm. We often use the essential balm to remove glue residue on the stainless steel bowl and basin.
Q:Which companies will use aluminum sheet and coil?
Plants to make auto parts such as exhaust pipe thermal baffle, muffler thermal baffle and front thermal baffle.
Q:Is aluminum silicate roll felt the same as aluminum silicate acupuncture blanket?
No, the unit weight of aluminum silicate fiber felt is greater than that of aluminum silicate acupuncture blanket. Both are thermal insulation and fire-proof material and have the same function.
Q:What’s the difference between aluminum tile, coil and sheet? Why?
Wood pallet is often used, which is easy to transport and can ensure the safety of products.
Q:Why the aluminum sheet crack after?
What I want to add is to choose such welding wires as 5383 or 5183 wire whose magnesium content is higher than 5754 wire. The loss of magnesium due to high temperature in welding process may reduce the intensity of welding area.
Q:Why does the end face of aluminum coil have grease spots?
Process one without coolant to see whether there are spots. There is a layer of alumina membrane on the blank face of aluminum coil, which will react with basic coolant when heating through processing.
