Features:

• Patent of Individual roll drive is put to use, it means that each roll is driven by a independent reducer, in this way, the mechanical interference between plate and drive roll and negative torque can be eliminated , the use life of work roll is prolonged and working roll surface is protected.

• The adoption of individual roll drive can realize the leveling method of linear decrement pressing for medium & thick plate. Because it conforms to leveling principle of steel plate, the mechanical efficiency and greatly increase the leveling precision at a time. At the same time, compared with deformation of parallel bended, such action reduces the material deformation. Therefore, aggregate leveling force and power consumption are reduced correspondingly.

• Variation of rolls, leveling rolls vary between n+2 and n, which take into account unparallel leveling requirement ranging from thin to thick plates and expand the leveling scope of the machine.

• It adopts combined pressing device of mechanic and hydraulic power, leveling and pressing can work together, and the reduction can be adjusted at random and controlled precisely. Pressing efficiency is greatly increased.

• Integrated closed stander is adopted, it has smooth great circular arc on each corner and reasonable rib plate distribution. The rigidity of the machine is greatly increased.

Wide and Heavy Plate Leveling Machine with Prestress

•Prestress framework structure: Prestress tie bars and frame upright shaft cause the tensile and compressive deformation respectively is under pre-tightening force. When the leveling machine is under work force, the former will be redistributed, while the latter will be increased and the press of the upright shaft will be decreased .Therefore the performance of components material has a full development.

•Small roll spacing and Small roll diameter: In order to improve the quality of leveling quality, it adopts the type of small roll spacing and small roll diameter. Due to the small diameter of the work roll, the force is larger, so it adopts the dense arrangement of supporting roll. Such arrangement can increase the level stiffness of work roll, and the effect of roll bending is better.

•The position of the straightening roll can be adjusted separately: According to the straightening technique requirement, this structure type can flexibly adjust the pressure, to enable each straightening roll reaching its optimum state and reducing straightening times.

• Technique control system: Computer models, according to the thickness and width of the steel plate, straightness and temperature, can set rolls gap and automatic bite and feed steel. It also owns the function of overload protection and AGC bounce compensation etc.

• Force parameter on-line measurement technique: Through the strain foil, it tests, displays and processes the online four road deformation and strength parameters when the medium plate rolling leveler is working, and it is provided with alarm function.
