Q:What does "steel roll number" mean?
Steel coil number is the specification of steel coil.
Q:Can cold rolled galvanized steel coils be acid washed after oxidation?
Hot rolling is made of slabs (mainly continuous billets) as raw materials. After heating, strips are made from roughing mills and finishing mills. From the last finishing mill stand out of the hot strip laminar cooling through to the set temperature, the coiling machine rolled strip steel roll cooled, according to the different needs of users with different finishing line (flat, straightening, transverse or longitudinal, inspection, weighing, packing and marking etc.) processing and become steel, flat steel product volume and slitting.
Q:Where do I need hot galvanized steel coils and color coated rolls?
The use of galvanized steel for color coated steel substrates, except zinc protection, organic coating on the zinc layer up covering the isolation effect, can prevent rusting steel, galvanized steel service life is longer, the coating steel plate galvanized steel long service life is 50%. However, the service life of the color coated plate with the same amount of zinc coating, the same coating and the same coating thickness will vary greatly in different regions and different parts.
Q:How can the outer diameter and weight of steel coil be converted?
Of course, the calculation is relatively coarse, and the volume has a lot to do with the tension.
Q:Aluminum alloy rolling doors and color steel shutter door that good
Among them, aluminum alloy rolling doors and ordinary rolling doors, both from the appearance, environmental protection or safety, have considerable advantages. Aluminum Alloy doors can be sprayed on the surface of various colors and patterns, but also with the concavity of the wood, sand grain coated, highlight the noble temperament, improve grades, if it is used in shops, you can let your talent shows itself in many shops in the.
Q:How are steel tape measures installed?
Today, I met similar situations at work! Accidentally pull the head, and then automatically can not go back, after opening, winding, after installation, can not automatically withdraw! After a long time, we suddenly noticed that we neglected a small place!
Q:What is the material of steel coil 08F and what brand can be used instead?
20 steel used for various mechanical parts is not subjected to great stress and toughness, such as rod, sleeve, screw, lifting hook; also can be used for manufacturing in 60 pressure and 450 DEG C using non corrosive medium pipes, pipe; can also be used for carbon and cyanide carburized core strength is not the chain, such as bushings, roller, shaft and gear, sprocket and other important.
Q:What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
The difference between hot rolled primary and hot-rolled carbon thin steel coils is that they include carbon steel rolls and low alloy steel coils.
Q:A roll of 1 meters wide color steel roll about how many tons?
In general, between 3.5 and 5 tons. Our company uses 0.17*1000 white color steel roll. The weight is usually around 4.5 tons. Different manufacturers will have different sealing rolls.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
Generally, according to the volume measurement, each roll weighs 3~15 tons.
