Cold hard rolled plate

Performance, due to the hot rolled coil through the cold rolling process directly to get the cold hard coil in the cold rolling process hardening, resulting in increased yield strength, and residual part of the internal stress, the external performance of the more "hard" so called cold hard coil.

DETALLES

Cold rolled plate is ordinary carbon structural steel cold rolled plate, is made of ordinary carbon junction of water steel hot rolled steel strip, after further cold rolling of the steel plate. Shandong Huixin under the Shandong Tang Rong New Materials Co., Ltd. has a six-roll reversible cold rolling mill set of seven (sets), by the Xi'an Prudential Metallurgical general contracting, Baowu Iron and Steel Changzhou Baoling Heavy Industry processing and manufacturing, the design capacity of 1.68 million tons per year.

Performance Characteristics

1, the appearance of the general cold hard coil plate a little hair slightly black.

2, surface quality, structure, dimensional accuracy of cold rolled sheet to be better than cold hard coil.

3, performance, due to the hot rolled coil through the cold rolling process directly to get the cold hard coil in the cold rolling process hardening, resulting in increased yield strength, and residual part of the internal stress, the external performance of the more "hard" so called cold hard coil.

Production process

Cold rolled sheet is a product made from hot rolled coil as raw material and rolled below recrystallization temperature at room temperature. Cold rolling is rolling under the recrystallization temperature, but is generally understood as rolling using room temperature rolling materials. It is mostly used in automobile manufacturing, electrical products, etc.

The production process is not heated, so there is no hot-rolled often occurring pitting and iron oxide and other defects, good surface quality, high finish. Moreover, the dimensional accuracy of the cold rolled products is high, and the performance and organization of the products can meet some special requirements, such as electromagnetic properties, deep drawing properties.

Applications

Cold rolled sheet has a wide range of applications, mainly used in automotive, printing iron barrels, construction, building materials, bicycles and other industries, but also the production of organic coated steel plate ideal choice.
