China sheet rolling machine

As the core equipment of metal pressure processing,the technological progress of sheet metal rolling mill directly promotes the upgrading of downstream industries.After decades of development,China's sheet metal rolling mill has formed a complete application system covering steel,non-ferrous metals,new energy,aerospace,automotive,construction and other fields.This article systematically reviews the application scenarios and technological value of China sheet rolling machine from three dimensions:traditional industrial foundation,manufacturing breakthroughs,and empowerment of emerging industries.
1、Traditional industrial sector:supporting the lifeline of the national economy
1.Steel industry:full chain coverage from plain carbon steel to alloys
China sheet rolling machine,and plate mills are the core link of the steel industry chain
Wide and Thick Plate Rolling Mill:
Application scenario:China's plate rolling mill produces steel for ships and marine engineering,pressure vessel steel,and bridge structural steel.
Technological breakthrough:The 5500mm plate rolling mill in China can roll 5-400mm thick plates,meeting the environmental needs of South China Sea island construction,deep-sea drilling platforms,and other projects.
Hot rolling mill:
Capacity scale:There are over 200 domestic hot rolling production lines,with an annual production capacity of over 300 million tons,accounting for 40%of the global total;
Typical products:automotive beam steel,pipeline steel,galvanized sheet for household appliances.
Cold rolling mill unit:
Precision control:Stable production of 0.15mm ultra-thin cold-rolled sheet is achieved through technologies such as six roll UCM rolling mill and laser velocimeter;
Market application:Tin plated sheets for home appliance panels and food packaging in China's sheet metal rolling mills.
2.Nonferrous metal industry:lightweight revolution of aluminum,copper,and titanium
China sheet rolling machine material lightweighting and performance upgrading in the field of non-ferrous metals:
Aluminum strip rolling mill:
Automotive application:China sheet rolling machine 5xxx/6xxx series aluminum alloy body panels,replacing traditional steel plates to reduce weight by 30%-50%;
Packaging field:Southwest Aluminum produces 0.0065mm lithium battery foil on an 8000 ton horizontal rolling mill,with a thickness of only 1/10 of a human hair.
Copper strip rolling mill:
Electronics industry:Ningbo Jintian Copper Industry uses a four roll irreversible rolling mill to produce 0.035mm high-precision lead frame copper strip for 5G base station chip packaging;
In the field of new energy,we produce C11000 copper bars with a conductivity of≥98%to meet the needs of photovoltaic inverters and wind power inverters.
Titanium plate rolling mill:
Aerospace:Baotai Group produces TA15 titanium alloy plates using 2800mm rolling mill for C919 aircraft landing gear and engine blades;
Medical field:Production of 0.5mm medical pure titanium plates with biocompatibility up to ASTM F136 standard,used for artificial joint replacement.
The China sheet rolling machine"scale expansion"to"quality",and its application fields have extended from traditional steel to industries such as aerospace,new energy,and semiconductors.The technological value has been upgraded from"material forming"to"functional realization".In the future,with the integration of intelligent and green technologies,China sheet rolling machine performance and provide a"Chinese solution"for the transformation of the global manufacturing industry.
