Choice of 250mm thick billet, dual rough layout reversible binding. Product range ~ 18mm. Typical Product 5mm. Wide varieties of product requirements, good quality. The basis of content, including plant design, rolling a point of order, the crown of order, the rolling charts, annual production, the crown of order, the electrical heating calibration, intensity calibration roll, check auxiliary equipment, metal balance, fuel consumption calculation. In order to produce high quality hot rolled plate with the car, rolling on the piece thickness, convexity, surface finish requirements are high, the temperature more stringent system. Take roll edge heating, laminar flow edge block, to ensure thermal residual stress in a small volume products. Instrument using the new crown, high crown of information processing to achieve crown, flatness control, so that smooth surface, size and high precision coldrolled to provide qualified for the followup coil. New plant is equipped with hotrolled strip steel rolling technology and highly efficient model and conditioning systems, so that the strip thickness, flatness, width, endrolling coiling temperature control and high accuracy. Enable the production of products to meet the design requirements of the quality and variety to meet market demand. Keywords 1580 hot rolling mill, double reversible roughing, CVC rolling, strip for car 目 錄 III 目 錄 摘 要 ...........................................................................................................................
