Description
TECHNICAL FIELD

equipment, and in particular to, a plate and strip rolling process
oriented efficient and stable current applying manipulator and a
method thereof.
BACKGROUND
[0002] A rolling mill is commonly used mechanical equipment in the
metallurgical industry. In order to adapt to industrial
development, it is particularly important to explore a rolling
method under a new process. Under the new process, new equipment is
needed to be designed to support the new process.
[0003] Studies have shown that electroplastic effect can greatly
increase forming limit of materials, and the current-assisted
forming process has achieved good application effects in many
fields. The electroplastic effect not only affects mechanical
properties during the material forming process, but also affects
recovery and recrystallization, which can achieve the purpose of
improving micro-structures of the materials. In a current-assisted
machining process, instantaneous high-energy pulse current is often
applied, which make materials obtain sufficient energy within a
very short time, promote movement of dislocations to increase a
rate of recrystallization and a nucleation rate of
recrystallization, so that the materials recrystallize at a lower
temperature than theoretical recrystallization temperature.
[0004] At present, in the field of plate and strip rolling, related
scholars mostly apply pulse current to cold rolling of thin strips.
The current is directly loaded through a roll or both ends of a
strip. The current directly acts on the roll to integrally
electrify the rolling mill, which will cause potential safety
hazards; and meanwhile, current loss is caused and the service life
of the roll is easily shortened when current passes through a
large-diameter roll. At the same time, it is difficult to apply
pulse current to a rolling process of a metal strip with a limited

cracks and a low yield, which are liable to occur in a rolling
process as sides of plates in a conventional hot-rolling process
are high in cooling speed are improved; after pulse current is
applied through the manipulator, the sides of the plates which are
in contact with the side rollers are quickly heated up as a result
of a small contact area, so that the cooling speed in the rolling
process is greatly reduced; for the materials which are liable to
crack, pulse current can be applied to inhibit side cracks by
reducing the cooling speed; plates pass through the roll in a
rolling process, so that crystal grain lengthening, crystal grain
refining and recrystallizing can be generated inside the materials
along with pulse current under action of rolling force. In such a
manner, residual stress after material rolling is effectively
reduced, and deformation resistance of materials can be effectively
reduced by electroplastic effect. For composite plate rolling, each

dislocation of an unrolled area of a dissimilar material in the
rolling process is effectively inhibited, and efficient stable
loading of pulse current is realized; and in the rolling process,
pulse current parameters, the rolling temperature and the rolling
rate are controlled to achieve the purpose of controlling the types

and the second servo motor 401 drives each ceramic roller 4 through
a synchronous tooth-shaped belt (also referred to synchronous belt)
and synchronous belt wheels 403.
[0051] A using method of the plate and strip rolling process
oriented efficient and stable current applying manipulator applies
pulse current to the pulse current applying assemblies on the first
rack 2 and the second rack 3.
[0052] In a further optimized scheme, positive pulse current is
applied to two pulse current applying assemblies on any one of the
first rack 2 and the second rack 3, and negative pulse current is
applied to the two pulse current assemblies on the first rack 2 and
the second rack 3 which are not applied with the positive pulse
current.
Embodiment 2
[0053] The difference between the using method in the Embodiment
and the using method in the Embodiment 1 is that positive pulse
current is applied to the pulse current assemblies on the same
sides of the first rack 2 and the second rack 3, and negative pulse
current is applied to the pulse current assemblies on the other
same sides of the first rack 2 and the second rack 3.
Embodiment 3
[0054] The difference between the using method in the Embodiment
and the using method in the Embodiment 1 is that positive pulse
current is applied to the pulse current assembly on one side of the
first rack 2, and negative pulse current is applied to the pulse
current assemblies at different sides of the first rack 3 and the
second rack 2.
[0055] In the descriptions of the invention, it is to be understood
that orientation or position relationships indicated by terms
"longitudinal", "transverse", "upper", "lower", "front", "back",
"left", "right", "bottom", "inner", "outer" and the like are
orientation or position relationships shown in the drawings, are
adopted not to indicate or imply that indicated devices or
components must be in specific orientations or structured and
operated in specific orientations but only to conveniently describe
the invention and simplify descriptions and thus should not be
understood as limits to the invention.
[0056] The embodiments described above are only intended to
describe the preferred embodiments of the invention, and are not
intended to limit the scope of the invention, and various
modifications and improvements made to the technical solutions of
the invention by a person skilled in the art without departing from
the spirit of the invention are intended to fall within the scope
as defined by the claims of the invention.
