Description
Technical field
The present invention relates to a kind of devices for manufacturing super-high strength steel plate, and superelevation is manufactured on assembly line more particularly, to one kind
The device of strength steel plate.
Background technique
Since the mid-90 in last century, the demand of China's strip is increasing, and unimach is in alloy
Grow up on the basis of structural steel, mainly for the manufacture of undercarriage and girder, solid rocket motor case, high speed
Centrifuge rotary barrel and other heavily stressed structure members of receiving.With the development of science and technology, the society of unimach
Demand is increasing, and application field also starts constantly to widen.
Since 2000, the industrial revolution of big production of machinery industry has obtained huge development, and economic globalization makes vapour
Vehicle steel using amount increases, auto output increases, and while bringing convenience to people's trip, also produces oil consumption, discharge and traffic
Safe three major issues.The effective means for solving energy consumption and environmental problem is automotive light weight technology, and lightweighting materials are divided into two major classes: one
Class is the light material of low-density, such as aluminium alloy, magnesium alloy；Another kind of is high-strength material, such as high-strength steel sheet, drop stamping
At fashioned iron and high strength steel cast iron etc..Plate is the principal item of automobile steel, and according to intensity difference, plate can be divided into tradition
Low-intensity mild steel, high strength steel and unimach.From the perspective of performance, in order to meet vehicle safety, collision property and
The requirement such as fatigue resistance, and raising formability and surface quality, automotive sheet need to have lower plane respectively to different
Property and higher elongation percentage, bending property and reaming performance etc..The application of high strength steel hot rolled plate in recent years than wide, but
It thickness specification, it is slight and in terms of there are a little deficiencies, and automotive light weight technology proposes steel demand structure
Tightened up requirement is gone out, therefore hot rolled plate overall consumption on car is little, hot rolled plate is mainly used in stamping parts of trying to get to the heart of a matter, vehicle
Account for about 10% with it, body structural member uses high-strength steel sheet mostly.
Steel production technology traditional at present has been mature on the whole, and applies to the research and development of Iron & Steel Material of New Generation
Become the top priority of 21 century steel material, a large amount of advanced technologies for preparing high strength steel iron material meet the tendency of and
It is raw.Crystallite dimension is an important factor for influencing material mechanical performance and physical property, and refinement crystal grain can significantly improve material

Also good application prospect is had in journey.Since the steel of crystal grain refinement has high intensity and toughness, in the application of building accouterment
Aspect has a extensive future, therefore the technology of preparing of fine-grained steel has become the focus of high-strength material research field.Preparation is high at present
The method of strength steel includes: intense plastic strain (SPD), low-carbon martensite cold rolling, Equal Channel Angular Pressing (ECAP), high pressure torsion
(HPT), Processed by Accumulative Roll-bonding (ARB), multiway forging (MDF) etc..Wherein more induce one to infuse with large plastometric set (SPD) technology especially
Mesh, it, which has, refine to nanoscale great potential coarse grain material, so that material has high intensity.Traditional is common low
The mechanical strength hardness of carbon steel is lower, obtains nanometer then by crystal grain refinement by available low-carbon martensite after quenching
The crystal grain of size obtains high strength steel to improve the intensity of low-carbon martensite, and this technique is widely used at present.
Unimach used in body of a motor car material requires have enough hardness, intensity and the energy for resisting adverse circumstances
Power, and the light quality of automobile board itself, and need to meet the requirement of automotive light weight technology and energy-saving and emission-reduction, existing system
The technique of standby high strength steel takes time and effort, and production efficiency is relatively low, and mechanization and the degree of automation are poor, it is difficult to meet people to height
The demand of intensity steel quality sum number amount, so how to improve the process units of high-strength steel sheet even ultrahigh-strength steel plates,
The technical problem urgently to be resolved as those skilled in the art.
