Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
Cold rolled steel coils are generally sprayed antirust oil, according to user requirements, light, medium, heavy oil 3 types. Nevertheless, if the oil is volatile or in a humid environment, the steel plate comes into contact with the water for a period of time, indicating that it is beginning to rust.
Q:Why cold rolled stainless steel sheet is lower than cold rolled stainless steel coil?
Kaiping is the flat coil set into common size. A negative tolerance is the actual thickness of the plate, not the thickness of the mark.
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
But this kind of steel coil is not well processed in the market. At the beginning of Wuhan, several processing plants are good at processing, and other processing plants usually process 1850 at most.
Q:Why is the steel tape tape head not fixed?
There are better tape measures, heads and magnets. For measuring steel objects, one can operate long distances.
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:The difference between aluminized color steel roll and ordinary color steel roll
Substrate selection: AZ150 (aluminum zinc content 150g/m2); G345A high strength galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon) corrosion resistance data: 5%NaCL 35 DEG C, 1000Hrs, Field good, Scribe, No, Blister, 2mm belowQ.U.V: 2000hrs, MAX.2 color, light to keep the rate above 90%, the above data show that aluminum zinc coated board (AZ150, G345A, PVDF) is very suitable for the extreme environment of buildings or other facilities, highly corrosion resistance and weather resistance, and the major steel plate can ensure the service life of 20 years. In addition, high strength steel has been widely used abroad, and it has good economic performance, and it is also the domestic development trend.
Q:Several reading methods of steel tape measure
Indirect reading methodIn some parts of the steel tape can not be used directly, can use the ruler or ruler, the zero alignment measurement, ruler and measurement direction; steel tape measure distance to a whole scale ruler or ruler, with more than a long reading amount. (3).Some errors in measuring steel tape
Q:What is the accuracy of steel tape inspection
This is the smallest scale brothers precision measuring tools, minimum scale steel tape is mm, mm is estimated to read out the data, such as steel tape measure length is 12.5 mm, which is 12 in the steel tape on the scale with the number of 0.5.It was read out. So the accuracy is millimeters.
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:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel.
A steel strip is a steel strip of relative range, and can be called a steel strip when the width is less than 1000.
