The strongpoint of this industry is have great output of the production is the variety production. and the produce process is very mechanization and steeling is a important technology to fulfill the country with the development of steeling industry the industry integrate very well with the traditional mechanism industry. How to make use of the steeling manufacture technology, enhance the rolling quality of the production, decrease the product of rolling time,enhance the rate of product useful rolled steel .The straighting technology is a important tache to enhance the surface quality and flatness of the production .This article describes the reasons inflatedness occurred on medium and heavy plate.The type of levelers,the determination of basic parameters,energetic date for 2600 plate leveler,the decision for complete structure and design,the development of plate leveling technology .This article design basis on the board-strip straighting machine produce process and the working principle in the steel metallurgy. This article first begin with the scheme review of the energetic date for 2600. Then go along with choice of the pressure electromotor, the design and checking of pressing the nut and the pressure screw, Worm and worm gear design and checking the life of the designed the local assessor and the over all structure. Besides researched the development direction of the straighting machine .
