Description
Technical Field
The invention belongs to the technical field of ultrathin strip rolling, and particularly relates to a method for rolling an ultrathin strip based on laser energy field assistance.
Background
With the recent rise of industries such as micro-manufacturing and micro-electro-mechanical systems, the market demand for ultra-thin strip products is rapidly increased, and especially the high and new technical fields such as robots and intelligent manufacturing have higher requirements on high quality and ultra-thin strips, for example, a blood vessel robot for blood vessel minimally invasive diagnosis and operation uses a micro motor with the diameter of 1mm as a driver, and the total length of a machine body is about 6mm, namely, the test is about to be put into practice. A micro-aircraft with the weight less than 100g and the overall structure size less than 15.24cm, and the like. These sophisticated fields require micro-materials, smaller micro-device sizes, and higher precision requirements.
The production level of the ultrathin strip products is the key for promoting the miniaturization of the products and accelerating the intelligence of the products, but in the cold rolling production process of the ultrathin strips, when the thickness of the foil is reduced to a certain degree, the thickness of the rolled piece is not reduced continuously even if the rolling force is increased continuously, namely the ultrathin strip has the minimum rollable thickness. And the cold rolling of the extremely thin strip easily causes the rolling roller system to generate larger elastic deformation, and related researches show that when the extremely thin strip reaches the minimum rollable thickness, tens or even hundreds of passes of rolling are usually needed, which can cause very serious work hardening phenomenon, thereby causing the defects of edge crack, edge wave and the like of the extremely thin strip, reducing the yield and causing the waste of raw materials and energy. Therefore, how to obtain an ultra-thin strip with extremely thin thickness, high dimensional accuracy and stable performance has become a difficult problem in the field of plastic processing.
The hot rolling can obviously improve the plasticity of the metal and reduce the deformation resistance of the metal, thereby greatly reducing the energy consumption of metal deformation, reducing the energy consumption and saving the cost. The traditional plate strip heating mode is not suitable for producing ultra-thin strips due to the problems of slow temperature rise, serious oxidation degree and the like.
Disclosure of Invention
The invention provides a method for rolling an ultra-thin strip based on laser energy field assistance, aiming at the problems of severe cold rolling work hardening, slow temperature rise of a hot rolling work heating mode, severe oxidation degree and the like.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for rolling an ultra-thin strip based on the assistance of a laser energy field comprises the following steps:
step 1, preparing an ultrathin strip, threading the ultrathin strip on an ultrathin strip rolling production line, and applying tension to an outlet and an inlet of the ultrathin strip after threading is finished; the tension is applied to reduce the occurrence of plate-shaped defects such as bubble waves, edge waves, middle waves and the like in the rolling process;
step 2, arranging a laser emitter near an inlet of the multi-roll mill to apply a laser energy field to the ultra-thin strip, adjusting the incident angle of laser through a focusing module and simultaneously improving the laser energy, fixing the ultra-thin strip after the position of a rectangular light spot is adjusted, opening the laser emitter to heat the ultra-thin strip, and enabling the ultra-thin strip to enter a roll gap at a constant speed under the action of a winder to realize uniform heating and stable rolling;
step 5, arranging a nitrogen purging device behind the ultrathin belt cleaning device, and performing secondary cleaning on the washed ultrathin belt to improve the surface quality of the rolled ultrathin belt;
step 6, arranging a drying device behind the ultrathin strip cleaning device to dry the ultrathin strip;
and 7, coiling the ultrathin strip through a coiler.
Further, the tension is 0.4 times of the yield strength of the ultrathin strip material.
Further, the width of the ultrathin strip is 10-50mm, and the thickness of the ultrathin strip is less than 1 mm.
Further, the power of the laser transmitter is 60-6000w and is continuously adjustable; the central wavelength of the laser is 1064 nm; the frequency range of the laser system is 0.05-50 kHz; the focal length of the laser system is 300 mm; the resulting laser spot was a 1.5mm x 50mm rectangular spot.
Furthermore, the material of the ultra-thin strip is a metal material.
Further, the ultra-thin belt cleaning device is an ultrasonic vibration auxiliary cleaning device.
Further, the width of the extremely thin strip is not more than the width of a laser spot.
Furthermore, the drying device is also provided with a circulating fan, and hot air circulation is realized inside the heating pipe.
Compared with the prior art, the invention has the following advantages:
the laser energy field auxiliary heating has the advantages of high heating efficiency, oxidation resistance, convenience in operation and the like, and the temperature of the normal-temperature ultrathin belt can be raised to hundreds of degrees centigrade in a short time by using instantaneous energy generated by laser emitted by a laser. The ultrathin strip after laser heating greatly reduces the metal rheological stress, can effectively reduce the elastic deformation of a roller system during rolling, thereby improving the shape of the strip, and is more favorable for recrystallization so as to refine grains.
The invention introduces the laser energy field to heat the ultrathin strip in the process of rolling the ultrathin strip, improves the plastic deformation capability of the material, obtains the ultrathin strip with thinner thickness, and reduces the processing hardening generated in the rolling process by the dynamic recrystallization phenomenon generated in the hot rolling process when the ultrathin strip is heated to the recrystallization temperature by the assistance of the laser energy field, thereby inhibiting the edge crack and other defects of the ultrathin strip, improving the yield and improving the quality of the ultrathin strip. The heat effect of the ultra-thin strip in the rolling process is caused by the laser energy field in the ultra-thin strip rolling process, the diffusion capability of metal atoms is improved, the energy barrier is overcome, the grain refinement is realized, the ultra-thin strip with fine grains and tiny residual stress is obtained, and the method can be used for the batch production of the ultra-thin strip in industry.
