Product Description Hot-Rolled steel has been rolled at high temperature from a cast steel slab more than two inches thick into steel coil as thin as 1/16 of an inch thick. Because the steel is rolled hot, and the reduction from slab to coil is great, the coil surfaces are noticeably rough and slightly oxidized. It is recommended for precision thickness Hot Rolled Strip and high formability. Hot ... Shandong Zhengde Metal Manufacturing Co., Ltd

Product Description Hot rolled steel coils are hot rolled steel made into relatively thin flat pieces and wound up into coils, resembling a wound steel strip. Hot rolled steel coils are widely used in applications like home appliances where saving weight and aesthetic value is deemed essential. It is also frequently used as a work-piece for the further production of cold-rolled products. As a ... Shandong Zhengde Metal Manufacturing Co., Ltd

Product Description Zhengde Hot rolled steel is steel that has been roll-pressed at very high temperatures-over 1,700, which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and resulting in products that are easier to work with. To process hot rolled steel, manufacturers first start with a large, rectangular length of metal, called a billet. The ... Shandong Zhengde Metal Manufacturing Co., Ltd

Product Description Zhengde Cold rolled steel coil is made from hot-rolled steel coil as raw material, which is subjected to acid washing to remove oxide skin and then subjected to cold continuous rolling. The finished product is rolled hard coil. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard coil increase, and the toughness and ...

Shandong Zhengde Metal Manufacturing Co., Ltd

Cold-rolled coils use hot-rolled coils as raw materials. During cold rolling, the rolled pieces are rolled below the recrystallization temperature. Generally, steel rolled pieces are rolled at room temperature. Silicon steel sheets with high silicon content have high brittleness and low plasticity and need to be preheated to 200°C before cold rolling. Since no heating is performed during the ...
