Packaging steel strip manufacturer: cold rolled sheet production characteristic performance is good, many varieties, wide application

Packaging steel strip manufacturer: cold rolled sheet production features good performance, many varieties, wide application performance is good, many varieties, wide use. Another outstanding advantage of cold-rolled steel sheet is good performance, many varieties, wide use. Through & ndash; Cold rolling deformation degree of connecting with the appropriate heat treatment after cold rolling, can in a relatively wide range to meet the requirements of customers. Almost all such as automotive sheet must be approved by stamping forming, such deep drawing performance becomes the core issue of production and use of plate. Stamping steel is one of the main requirements of texture has a dominant advantage. Hot rolled sheet of plastic strain ratio r only today to 0. 8 - 0. 95, and the cold rolling the first generation of rimming steel car plate r is 1. 0 - 1. 2, the second generation of 08 al steel r is 1. 4 - 1. 8 and the third generation of cold-rolled automobile plate r is 1. 8 - 2. 8, which is out of reach for hot rolling. Silicon steel is one of the important materials of mechanical and electronic industry, the main users are the motor manufacturing and power transmission and transformation equipment manufacturing. Higher energy prices, energy crisis, inevitably requires the use of low energy consumption of materials, so I started out in the 1960 s high energy consumption of hot rolled silicon steel sheet, cold rolled silicon steel sheet instead. With no orientation of 100000 t cold-rolled silicon steel manufacturing motor than with 100000 t hot rolled GuiGang manufacturing, the measured energy saving 1. 9. 8 billion kW· H/a, the motor running 10 years is equivalent to save a plant annual capacity of 200000 kW. With cold Zagreb and 360000 kV· GuiGang piece of production; A transformer that is the total weight of 204 t, and made A 120000 kV· hot rolled silicon steel sheet; A transformer, its weight is 200 t, therefore, use cold rolled silicon steel sheet instead of hot rolled silicon steel sheet is of great economic benefits. Cold can also produce stainless steel plate, used for furniture and architectural decoration, chemical industry, etc. Has a great development in recent years, surface treatment of steel. With manufacture as the substrate is a great variety of coated steel plate, has extensive USES. For these reasons, cold rolled sheet production got rapid development. From the production point of view, the general manufacture production accounted for about 20% of the total rolling production, and the process technology and equipment innovation. Early manufacture speed is less than 1 m/s, and now has reached 41. 6 m/s。 Steel plate width is 406 mm, 1905, 1925 is 914 mm, and now the width is 2337 mm. Coil weight also from several tons to 60 t. A modern abrasion annual output can reach 2. 5 million t.
