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?
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 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
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: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:What's the length of a coil of cold rolled steel? Is there a standard?
In 2.0*1000*C calculations, it is assumed that the formula for the length of 5T in this volume is 5000/ (2.0*1000*1000*7.93) = the total number of meters. First, the weight of one meter is calculated by dividing the total weight by the single weight, that is, the theoretical length of the volume
Q:How to solve steel plate storage
According to the principle of "first in first out" to carry out the turnover, organize the logistics, reduce the large amount of moving plate, reasonable arrangement, easy to steel coil into the use of state.
Q:Is a steel plate the same as a steel coil?
Generally speaking, they can be used interchangeably, and the purchase price of the plate is slightly cheaper.
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:What is the difference between cold rolled strip and cold rolled steel coil?
Cold rolled steel strip: the width is below 900mm! Cold rolled steel coil: the width is above 1000mm! Materials and purposes are not very different, basically the same!
