Cold -rolled steel plate is referred to as cold -rolled. It is based on hot -rolled plate rolls. At room temperature, rolling is made under the crystallization temperature. Cold -rolled steel plates are steel plates produced by cold rolling processes, referred to as cold plates.The thickness of the cold-rolled plate is generally between 0.1--8.0mm. The thickness of the cold-rolled steel plates produced by most factories is below 4.5mm. The thickness and width of the cold-rolled plates are determined by the equipment capabilities and market needs of each factory.
Cold -rolled steel plate density
The density of cold -rolled steel plate DC01 is about 7.85.The thickness of the cold-rolled plate is generally between 0.1--8.0mm, and the thickness of the cold-rolled steel plate produced by most factories is below 4.5mm.
Cold -rolled steel plate specifications
The difference between cold -rolled steel plate and hot -rolled steel plate
The hot rolling is rolled into a relatively thin steel plate at a higher temperature of the steel plate; the cold rolling is rolled at the steel plate under normal temperature conditions.Generally, hot rolling first, and then cold rolling.When the steel plate is thicker, it can only be used to use hot rolled, rolled into thin plates, and then cold rolled.The hot -rolled steel plate is divided into two types: thick plate (thickness greater than 4mm) and thin plate (thickness of 0.35 ~ 4mm); cold -rolled steel plates only have thin plates (thickness of 0.2 to 4mm).The termination temperature of the hot rolling is generally 800-900 ° C. After that, it is usually cooled in the air, so the hot rolling state is equivalent to positive fire treatment.
Cold -rolled steel plate price
The price of cold -rolled steel plates is around thousands of yuan per ton, and its material and the different manufacturers affect the specific price of cold -rolled steel plates.The following is the price of different cold -rolled steel plates, as shown below: (unit: yuan/ton) (1) cold -rolled steel plate, material: SPCC/DC01, Liu Gang, Guangdong Shunde Chufeng Trading Co., Ltd. ￥ 2950.00 (2) Cold rollingSteel plate, material: Q195, Guofeng, specifications: 1.0mm-2.0mmMSPCC, Foshan Nanhai Yueteng Steel Co., Ltd. ￥ 3690.00 (3) Cold-rolled steel plate, material: DC01, Pan Steel, Chongqing Pengchuan Materials Co., Ltd. ￥ 4100.00 (4) Cold -rolled steel plates, materials: ST14, Ji Steel, Liaocheng Luguan Materials Co., Ltd. ￥ 4680.00 (5) Cold -rolled steel plate, material: GMW2MCR4, Wugang, Wuhan Steel and Red Materials Co., Ltd.
