Reasonable selection of cold rolling mill for stainless steel production
Overview: In the selection of stainless steel rolling mills, the properties of mills are comprehensively considered, model is reasonable chosen according to investor’s product usage, which increases the cost performance of equipment investment, ensures the proper selection of equipment, increases production capacity and realizes the best effect of capital investment and equipment invest.
In the selection of stainless steel rolling mills, the properties of mills are comprehensively considered, model is reasonable chosen according to investor’s product usage, which increases the cost performance of equipment investment, ensures the proper selection of equipment, increases production capacity and realizes the best effect of capital investment and equipment invest. Therefore, considering the factors of economy, technology, materials, production process, product grade, comprehensive benefit and energy saving, environmental protection, equipment adaptability, equipment precision and other factors, it is suggested that the following ideas can be followed when selecting the model of the reversing rolling mill.
Due to the obvious difference in chemical composition, the physical properties of different grades of steel vary greatly during the rolling process, so the performance requirements of different steel grades on rolling equipment are significantly different. Even if the same grade of steel is rolled, due to the different rolling conditions such as width, applied tension, pass reduction, rolling pressure, cooling and lubrication, etc., the performance requirements of rolling mills for products of different specifications are different. The wider and thinner the rolled strip is, the more factors on quality rolling process has and more complicate the wave type of strip surface is, thus more comprehensive adjustment measures and operation function are required on rolling mill to meet the demanding quality from the market and to produce the quality products for different times, different demands and different usages and ensure the manufacture remain invincible.
Therefore, combined with multiple factors such as economy, technology, material, production process, product grade, comprehensive effect, energy saving, environment protection, equipment adaptability, equipment precision, etc., The following thinking ideas are recommended for the selection of reversible cold rolling mill.
(1) When the width of the product is below 650mm, the thinnest finished product is more than 0.2mm, high–precision 4-high rolling mill can be selected. The thinnest finished product is non-special products between 0.1-0.2mm, 8-high rolling mill and 12-high rolling mill can be selected. The thinnest finished product is below 0.1mm and the above thickness has special uses and high-end requirements, 20-high rolling mill roll can be selected.
(2) When the width of the product is below 850mm, the thinnest finished product is more than 0.3mm, high-precision 4-high rolling mill is suitable for selection. The thinnest finished product is non-special products between 0.15-0.3mm, 8-high rolling mill and 12-high rolling mill can be good choices. The thinnest finished product is below 0.15mm and the above thickness of products with special uses and high-end requirements, 20-high rolling mill can be selected.
(3) When the width of the product is above 850mm, the thinnest finished product is more than 0.3mm, and high-precision 8-high rolling mill suitable for stainless steel can be used. The thinnest finished product is below 0.3mm and the above thickness has special uses and high -end requirements, 20 roll reversible cold rolling mill can be selected.
