The development process of rolling mill
DATE：3/31/2019 HIT：716 SOURCE： AUTHOR：
All over the world, steel has been widely used in various fields.And become the main raw material.About 90% of steel production is made by rolling.The production method of this mill has the advantages of many varieties, high efficiency, strong continuity of production process, easy to realize automation and mechanization.
Today, our country's rolling technology and rolling machinery in the continuous innovation of the gradual application and development, and the introduction of the world's advanced steel rolling process and technology.In the iron and steel market, the production and application of steel plate accounted for the largest proportion, from the introduction of Japan in 1981 1700mm hot continuous rolling mill trap equipment began, then rapidly rose a large number of hot continuous rolling mill with advanced production technology.Our country at the end of 1965 made experimental narrow plate 300 mm five-stand cold tandem mill, to west Germany in the 80 s and the introduction of the original production of 1700 mm five-stand tandem cold strip mill complete sets of equipment, after the 90 s and into the six roll HC rolling mill, CV, mill used for production, by 2007, our country's hot rolled wide strip is the annual production capacity will reach 55 million tons.
The development of hot continuous rolling mill mainly includes the following aspects: preferred to use accelerated rolling, improve the output just now, the steel unit of hot continuous rolling steel plate export speed has been increased from the 1950s 10m/a-12m/a to now 35,/s, and toward a higher speed development.And the use of full computer control, more improved the level of automation;There are product specifications to increase, improve accuracy and so on.Today's steel plate hot continuous rolling mill is developing towards large-scale, high-precision and high-speed automation.
