The temperature drop model for finishing stand set of medium-wide strip hot continuous rolling line of Jianlong is introduced,the data is calculated for the development of weather-resistant steel of SPA-H and it is closed with the site measurement.

The reconstruction of hydraulic AGC system of 750mm hot medium-wide strip continous mills of Tianjin Rock Check Iron & Steel Company was started from July,2006.

The varieties and gauges,processing characteristics and the equipment performance of the medium-width strip mill of Lingyuan Iron and Steel Group Cowere introducedThe advantages and existing problems of this mill were pointed out,and its reformation schemes were introduced too

This paper introduces the production process of 08Al hot rolling mid-wide strip by adopting converter smelting,blowing argon and wire feeding,slab continuous casting and hot rolling,and the production technology and parameters of main process of developing 08Al superior atmospheric corrosion resistance mid-wide strip.
