Heavy plate rolling machine

A heavy plate rolling machine is a specialized steel rolling equipment used for rolling medium thickness steel plates,and the thickness of the steel plates produced is usually above 6mm.This equipment,with its powerful rolling force and high-precision control system,has become an important production tool for many national key raw materials.The specifications of thick heavy plate rolling machine are generally based on the length of the working roll surface,such as 2300mm,2800mm,5500mm,etc.In recent years,China has made significant breakthroughs in this field,successfully developing a wide 5600mm wide heavy plate rolling machine,marking a new era in the world's wide heavy plate rolling machine technology.
The thick heavy plate rolling machine is usually composed of a working machine base and a transmission device.The working machine base mainly includes key components such as the rolling mill frame,roll system,balance system,pressing device,and roll changing device.The transmission device consists of a large electric motor and a reducer,responsible for providing the necessary rotational power for the rolling mill.Modern heavy plate rolling machine commonly use advanced hydraulic AGC(automatic control system for steel plate thickness),which greatly improves the accuracy and production efficiency of medium and thick plates.
During the working process,the steel plate is fed into the gap between the rollers in the rolling mill.Through the rotation and pressing action of the rollers,the steel plate is continuously thinned and formed into a strip of the required width and thickness.The rotation direction and speed of the rolling mill can be adjusted according to production needs to finely control the thickness and shape of the strip.In addition,modern thick heavy plate rolling machine are equipped with multiple advanced technologies,such as bending roll technology,roll eccentricity control,and increasing the diameter of support rolls.The application of these technologies has played a significant role in reducing sheet thickness deviation and improving sheet shape.
The thick plate products produced by the thick heavy plate rolling machine are widely used in various fields such as ships,petrochemicals,equipment manufacturing,electricity,and construction.Especially for ultra wide and thick plates,as strategic materials,they are also key raw materials for many national treasures.For example,in aircraft carriers and large shipbuilding,extra wide and thick plates play a crucial role,as they must be able to withstand enormous impact forces and high-temperature flames while ensuring sufficient strength and toughness.In addition,in the field of petrochemical construction,the construction of long-distance oil and gas pipelines also relies on high-quality extra wide and thick plates.
The importance of the heavy plate rolling machine as a core equipment in the steel manufacturing industry is self-evident.With the continuous advancement of technology and diversified market demands,it will continue to play an increasingly important role.In the future,we look forward to China achieving more innovative achievements in heavy plate rolling machine technology and contributing more wisdom and strength to the development of the global steel industry.
