Study Of Heavy Plate Plan View Pattern Control Of 4300 Plate Mill

In the people’s livelihood and national construction, heavy plate products in various fields of application is very extensive, such as ships, vessels, boilers, oil and gas transportation pipeline,marine, bridge structures, construction, hydropower, wind power and many other fields. In the actual production of the wide and heavy plate, how to improve the rate of finished products is all iron and steel enterprises to save resources, reduce the cost of research direction. The production technology of flat shape control is a key technology in the production of heavy and heavy plate. The paper takes the first Qin 4300 mill as the research object, and studies the realization method and effect of the product plane shape control function during the rolling process of heavy plate.. The main research contents are as follows:(1) The deformation theory of the plane shape of heavy plate rolling is discussed.. Mainly introduces the MAS rolling and normal rolling strip of neutral angle, the nip angle, contact arc length and slip and backward slip value parameter changes, analysis the MAS rolling process of metal flow and deformation rules.(2) Introduced 4300 descaling equipment, rolling mill equipment, water equipment, cooling bed, shearing equipment and other production equipment, understand each equipment production capacity, so that the subsequent conventional rolling and MAS rolling contrast study provides solid foundation for equipment.(3)Introduces thecontrol function to improve the shape of a flat plate rolling mill is the4300. According to the parameters of mill production procedure and field finite element analysis model is established(4) According to the choice of 4300 rolling mill rules of finite element simulation, the rolling spread ratio of plate and strip products planar shape effect, different spread ratio and thickness compensation combined product of planar shapes impact on board.Through the calculation rules and the scene of the actual situation with good agreement,to optimize and improve rolling schedules have draw lessons from a meaning.。...
