The medium plate manufacturing technology will develop fast along with the development of the steel industry and change of the requirement of the downstream industry. The tendency of the medium plate’s product development is mainly on the highstrength, special utility ones, tendency of the manufacturing technology is mainly on the TMCP and microalloy technology, subsidiary technology are the detection, blast grit, and heat treatment which meets the special requirement of the downstream customers. This design can be divided into 9 chapters, mainly introduced are the development of medium plate in our country, the necessity and reliability of this plant in Baotou area, Design production capacity of 1， 400， 000 tons of plate plant to 12mm 2500mm 6000~12021mm of Q345B carbon structural steel products for the typical product. The design information through access to relevant literature, product schedule, process, equipment, table of rolling, annual output, subsidiary equipment, strength test and the test of the engine power, and the last chapter is the layout of the workshop.
