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:What brand steel tapes are of good quality?
Personal feeling is also good for the Great Wall Seiko tape, upstairs several estimates are the production of steel tape manufacturers, of course, that their goods well. Our unit now buy all the Great Wall Seiko goods, said the tape is good, not because it is so durable
Q:On how to reinforce steel coils in a container
The inside of the container is rectangular, four angles with hook, so can the packing time for warehouse experienced workers in the upstairs said, with the steel wire rope and steel reinforcement will lock up, if the mud coil is hollow, the wire rope through the middle and then cross to get on fixed on the four corners, and on the floor on the wooden wedge nail to prevent steel coil rolling.
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:How to solve steel plate storage
The warehouse temperature should be constant, prevent the occurrence of condensation, a horizontal steel coil to pile up, forced to pile up, in contact with each other at the coil not binding belt lock, steel roll room felt material, narrow roll on wide roll, roll on roll light. In order to facilitate the lifting, the steel coil and the wall should be kept a certain distance.
Q:Why can't the coil weight be too low?
And may make the level stacked steel coil collapse, rolling, produce production safety accidents.
Q:Cold rolled steel coil steel, what is the difference?
Hot rolling is made of slabs (mainly continuous billets) as raw materials. After heating, strips are made from roughing mills and finishing mills.
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
Q:Where are the coils and the steel plates used? Where did the steel plate come from?
The use of steel coils, refrigerators, washing machines, household appliances, and other industries, parcels are winding.Steel plates can also be found everywhere: airplanes, guns, trains, ships, space shuttles, spaceships, automobiles, etc..Steel plate through mining - sintering - iron smelting - smelting - forming.
Q:A roll of 1 meters wide color steel roll about how many tons?
Generally speaking, it will be about 4 tons, the export may be larger, but 10 tons of papers have not yet seen
Q:The strip tower height
Defects: cold-rolled steel sheet (coil)
