Steel coil, also known as steel. Steel hot pressing, cold forming into a roll. In order to facilitate storage and transportation, to facilitate a variety of processing (such as processing into steel, steel, etc.).
The roll is mainly hot rolled and cold rolled. The hot rolled coil is a processed product before the billet is recrystallized. Cold rolled coils are the subsequent processing of hot rolled coils. The weight of the coil is about 15-30T. This year, China's hot-rolled production capacity has been expanding, there are dozens of hot-rolled production lines, there are some projects to be opened or put into operation.
Rolled coil rolled mainly for large customers, the general user does not open the volume of equipment or limited use. So the subsequent processing of the coil will be very promising industry. Of course, the current relatively large steel mills have their own open and flat items.Steel Coil
Hot-rolled coil is slab (mainly continuous casting slab) as raw material, after heating by the roughing mill and finishing mill made of strip. The hot steel strip coming out of the last rolling mill is cooled to a set temperature by laminar flow, rolled by a coiler into a steel coil, and cooled.Steel Coil
Hot-rolled coil is slab (mainly continuous casting slab) as raw material, after heating by the roughing mill and finishing mill made of strip. The hot steel strip from the final rolling mill is cooled to a set temperature by laminar flow, rolled into a steel coil by a coiler, cooled steel strip, and subjected to different finishing operations according to the different needs of the user Line (flattening, straightening, crosscutting or slitting, inspection, weighing, packaging and marking, etc.) and become steel plate, flat roll and longitudinal steel products.
As the hot rolled steel products with high strength, good toughness, easy processing and good weldability and other excellent performance, which is widely used in ships, cars, bridges, construction, machinery, pressure vessels and other manufacturing industries.Steel Coil
