Cold rolled sheet products
Cold rolled (annealed) is cold rolled plate before winding after annealing obtained after annealing, hardening phenomenon, the internal stress is eliminated (i.e., greatly reduce the fall) the yield strength decreased close to before cold rolling.
Cold rolled coil is made of hot rolled coil, which is rolled at room temperature below the recrystallization temperature. The piece is called delivery plate, also known as box plate or plate; the length, volume of delivery called strip, also known as the coil.
Product classification
A rolling steel plate belongs to, is actually a long narrow sheet and roll into the supply volume, and almost flat is a cut packing.
Cold rolled plate is obtained by cold rolling pickling, hot-rolled coil. Can be said to be a kind of cold rolled coil.
Cold rolled (annealed): hot-rolled coil after pickling, cold rolling, annealing, and smooth (finishing) obtained.
The difference between cold rolling and hot rolling
1, the general appearance, a little cold rolled plate in ukraine.
2, surface quality, structure and dimensional accuracy of cold-rolled plate than cold rolled plate.
3, the performance, the hot-rolled coil after cold rolling process by cold rolled plate work hardening occurred in cold rolling, the yield strength increases, and lead to some residual stress, the external manifestations of the "hard" so that the cold rolled plate.
Cold rolled plate is greater than the cold rolled (annealed), the cold rolled (annealed) more conducive to forming.
In general, the default delivery status of cold rolled coil is annealed.
The products have been exported to the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran and other countries, to obtain customer acclaim.
