Description
Technical field
The invention belongs to cross-shear rolling technical fields, deformation Division more particularly to a kind of cross-shear rolling strip and each
The calculation method of subregion accounting.
Background technique
Asymmetrical rolling refers to a kind of upper working rolls and lower working rolls linear velocity not equal milling method；It is asynchronous to roll compared to symmetric rolling
Deformed area processed is there are the area Cuo Zha, unit pressure peak value when can eliminate symmetric rolling, has draught pressure low, and it is strong etc. excellent to roll thin ability
Point has some advantages in cold rolled sheet, is particularly suitable for the production of strip in razor-thin.
Draught pressure distribution, friction when asymmetrical rolling deformed area configurations and each subregion accounting size are to asymmetrical rolling
Power distribution, the fast distribution of working roll roll torque at a slow speed and fast distribution of main motor current at a slow speed etc. have a significant impact, and the latter is not only
Reference frame is provided for rolling mill design and rolling mill practice formulation, it is strong also to directly affect percentage pass reduction, unilateral volume defect and texture
Degree etc., therefore be of great significance to the division of asymmetrical rolling deformed area configurations and the calculating of each subregion accounting.
When asymmetrical rolling deformed area configurations are asymmetrical rolling in deformed area different stress subregions combination form；
Asymmetrical rolling stress subregion includes zone of slippage on the delivery side, zone of slippage on the entry side and the area Cuo Zha, and asymmetrical rolling deformed area configurations are as advancing slip
Area, zone of slippage on the entry side and the area Cuo Zha combination form；Each subregion accounting size is different stress subregions in asymmetrical rolling deformed area
The percentage of floor projection length and contact arc length ratio.
It is not comprehensive to the division of asymmetrical rolling deformed area configurations at present, not accurate enough and partially complicated, each subregion accounting
Only have accounting calculating in the area Cuo Zha in calculating and formula is complicated, it is not very practical；This makes asymmetrical rolling pressure-plotting model, friction
Power distributed model, fast working roll roll torque distribution model at a slow speed and the fast complexity of main motor current distribution model etc. at a slow speed and precision
It is limited, constrain the design of asynchronous rolling machine and the optimization of asynchronous rolling process.

The object of the present invention is to provide a kind of cross-shear rolling strip deformation Division and each subregion accounting calculation method,
The associated datas such as the discrepancy speed of speed and rolled piece based on speed working roll side more comprehensively accurately draw to deformed area
Point, and each subregion accounting is accurately calculated, simplify calculating process, calculates subregion and have more practicability.
The deformation limited region dividing method of cross-shear rolling strip of the invention are as follows:
1, state is slided according to the front and back that asymmetrical rolling deformed area configurations depend on rapid operation roller side and worked at a slow speed
The sliding state in the front and back of roller side, i.e. asymmetrical rolling deformed area configurations and rolled piece entrance velocity vH, rolled piece muzzle velocity vh, at a slow speed
Working roll linear velocity vs, rapid operation roller linear velocity vf, working roll side neutral angle α at a slow speeds, rapid operation roller side neutral angle αfWith
Nip angle αlIt is related；
2, when slow roll side is there are zone of slippage on the entry side and zone of slippage on the delivery side, quick roll side is worked as there is also when zone of slippage on the entry side and zone of slippage on the delivery side
vscosαs>vHAnd vfcosαf<vhWhen, deformed area configurations are the area zone of slippage on the entry side+Cuo Zha+zone of slippage on the delivery side；After quick roll side is complete
Skating area, and v is worked as there are when zone of slippage on the entry side and zone of slippage on the delivery side in slow roll sidef≥vhAnd vH<vscosαs<vhWhen, asymmetrical rolling deformed area
Configurations are the area zone of slippage on the entry side+Cuo Zha；When slow roll side is full zone of slippage on the delivery side, and quick roll side is there are when zone of slippage on the entry side and zone of slippage on the delivery side,
Work as vscosαl≤vHAnd vH<vfcosαf<vhWhen, asymmetrical rolling deformed area configurations are the area Cuo Zha+zone of slippage on the delivery side；Work as quick roll
Side be full zone of slippage on the entry side, and slow roll side be full zone of slippage on the delivery side when, that is, work as vscosαl≤vHAnd vf≥vhWhen, asymmetrical rolling deforms district's groups
State form is the area Quan Cuozha；When slow roll side is full zone of slippage on the entry side, that is, work as vs≥vhWhen, asymmetrical rolling deformed area configurations are
Full zone of slippage on the entry side；When quick roll side is full zone of slippage on the delivery side, that is, work as vfcosαl≤vHWhen, before asymmetrical rolling deformed area configurations are complete
Skating area.
In the above method, when according to cold rolled sheet, reduction in pass is small, contact arc length relative to work roll diameter very
It is small, i.e. αs→ 0, αf→ 0, αl→ 0, so cos αs→ 1, cos αf→ 1, cos αl→1；Asymmetrical rolling deformed area configurations are drawn
Method is divided to simplify are as follows:
Work as vs>vHAnd vf<vhWhen, asymmetrical rolling deformed area configurations are the area zone of slippage on the entry side+Cuo Zha+zone of slippage on the delivery side；
