Cold-rolled sheets have good surface quality, high dimensional accuracy and no oxide sheet due to rolled at room temperature. After annealing treatment, its mechanical properties and technological properties are better than hot-rolled sheet, mostly used of automotive, electrical products, locomotives, aviation, precision instruments, food and other industries.
In the planning and design of cold rolled mills, the following aspects need to be considered in order to meet efficient, safe and sustainable production.
1. Product planning
Should fully research the demand and trend of the target market, including the application field of the product, market capacity, competitors, etc., to determine the reasonable production scale and specifications of the product.
2. Project location
The geographical location shall have convenient transportation and perfect infrastructure for reducing operation cost. At the same time, factors such as local environmental policies, energy supply and labor resources should be considered.
3. Analysis of construction conditions: evaluate the natural factors such as topography, geological conditions, hydrometeorology, etc. of the construction site, as well as the supply of public facilities such as power, water supply and drainage, communication, etc., to ensure that the construction conditions meet the production needs of cold rolled mills.
4. Process design
According to product planning and market demand, design reasonable production process, including raw material preparation, pickling, cold rolling, annealing, finishing and other processes. At the same time, it is necessary to consider the coordination between various processes to ensure the continuity and efficiency of the production process.
5 Equipment selection
Select advanced cold rolling equipment, such as cold rolling mill, pickling unit, annealing furnace, etc.referencing the performance, efficiency, reliability and maintenance costs of the equipment. Meanwhile, it is necessary to reasonably plan the layout and installation position of the equipment to ensure the smooth operation of the production line.
6 Safety design
There are qualifed devices and meet the requirements of the relevant safety regulations and standards
7 Environmental protection
Comply with environmental regulations and standards, configure the corresponding technical equipment to control the discharge of noise, dust, waste water and other pollutants,
