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: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:Why is the steel tape tape head not fixed?
In this way, no matter how you measure, always be measured, from the ruler of the "0" bit began.The fixed ruler does not take this action when it is taken, which directly results in the thickness of the steel sheet that needs to be added or lowered to your readings;Activity design is designed to reduce error, and this is an advanced approach;
Q:The difference between aluminized color steel roll and ordinary color steel roll
Aluminized color coated sheet is a new type of material produced in China in recent years due to its high end applications. It is often used as an indication of CCLI. It is made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon), which is more galvanized and more corrosion resistant. It is processed by surface degreasing, phosphating and complexing treatment, and is coated with organic coating.
Q:How can the outer diameter and weight of steel coil be converted?
To obtain the outer diameter of the steel coil is calculated according to the density of 7850, according to the density, in general, hot-rolled is 0. 96~0, 98, cold rolled, according to 0. 98~0. Ninety-nine
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:Why can hot rolled coils be placed outside?
Because the stress of participation should be eliminated
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:Where do I need hot galvanized steel coils and color coated rolls?
In industrial or coastal areas, due to the influence of sulphur dioxide or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating has been soaked by rain for a long time, or the temperature is too large and easy to dew. It will be corroded quickly and the service life will be reduced. A building or building made of colored coated steel plates, often with a long service life when washed by rainwater, otherwise affected by sulfur dioxide, gas, salt, and dust. Therefore, in the design, if the roof slope is greater, the more difficult to accumulate dust and other dirt, the longer the service life; for those areas or parts that are not often washed by rain water, should be regularly washed with water.
Q:How are steel tape measures installed?
That's the tape measure. There's a small card with no card in the middle of the screw! So it can't be retracted automatically! The solution is to wrap the open tape to the end!
