Q:Can cold rolled galvanized steel coils be acid washed after oxidation?
If it has been galvanized, it can not be pickled, and if it is pickled, it may corrode the zinc layer
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
Q:Why can't the coil weight be too low?
Because the steel coil is stored in warehouse stacking level, if the coil weight is too low, resulting in a single coil capacity is reduced, so that the steel roll easily crushed and deformed;
Q:Steel coil from vertical to horizontal, what sling needs?
The sling has little effect, but it is easy to damage the surface of rolled steel.
Q:The difference between aluminized color steel roll and ordinary color steel roll
Ordinary color steel roll is a composite material, also known as color coated steel plate, is used in the continuous production line on the production line after surface degreasing, phosphating and other chemical coating treatment, painted with organic coatings, made by baking products. Both steel and organic materials are a little bit different. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance.
Q:What brand steel tapes are of good quality?
Personal feeling is also good for the Great Wall Seiko tape, upstairs several estimates are the production of steel tape manufacturers, of course, that their goods well. Our unit now buy all the Great Wall Seiko goods, said the tape is good, not because it is so durable
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
As far as I know, the galvanized rolls of WISCO are wider in width than other domestic steel mills, and can produce 2080 wide steel coils.
Q:Where are the coils and the steel plates used? Where did the steel plate come from?
Steel plate is divided into many kinds of PU, low alloy, boiler plate, vessel plate, high strength plate, etc..
Q:On how to reinforce steel coils in a container
The inside of the container is rectangular, four angles with hook, so can the packing time for warehouse experienced workers in the upstairs said, with the steel wire rope and steel reinforcement will lock up, if the mud coil is hollow, the wire rope through the middle and then cross to get on fixed on the four corners, and on the floor on the wooden wedge nail to prevent steel coil rolling.
Q:Why can hot rolled coils be placed outside?
Because the stress of participation should be eliminated
