Product Description

Brief Introduction
The Cold Rolled Steel  is steel that has been worked below its recrystallization temperature by passing it between a pair of rollers. Recrystallization temperature is the temperature at which grains in the lattice structure of the metal have been rearranged, leaving it free of strain and deformations. The Cold Rolled Steel  is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The Cold Rolled Steel  is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the Cold Rolled Steel  is further reduced, its strength and hardness both increase, but its ductility decreases. After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility. The final Cold Rolled Steel  may be manufactured in the form of sheets, strips, bars, or other forms.

Q:Cold rolled steel coil steel, what is the difference?
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, its strength is not very high, but the ductility and weldability is good, the appearance of color is not bright, easy to corrosion, because the price is cheap, the majority of enterprises in order to reduce the cost, so the more commonly used.
Q:In the warehouse management system of steel coil
The warehouse is set to be required under the factories and production equipment and manpower planning, reasonable layout; to strengthen the internal economic responsibility system, scientific division, forming material export management assurance system; the service must implement the work quality standard > standardization, application of modern management technology and the ABC classification method, and constantly improve the level of warehouse management.
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:Aluminum alloy rolling doors and color steel shutter door that good
Hello, the shutter door material mainly galvanized steel plate, color steel plate, aluminum alloy, stainless steel, PVC soft board, PVC soft door curtain.
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:The strip tower height
Defects: cold-rolled steel sheet (coil)
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!
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:On how to reinforce steel coils in a container
In the bottom and sides with a thick strip stuck, but also to ensure that the wood will not loosen down...... Rough steel rolls, I saw people loading and unloading on the docks, poked them directly with a small forklift truck, and then reinforced with wooden planks
Q:Why can hot rolled coils be placed outside?
Because the stress of participation should be eliminated
