Electromagnetic vibrating roller for rolling metal clad plate

Abstract

The invention belongs to the technical field of rolling of bi-metal composite materials, and particularly relates to an electromagnetic vibration roller for rolling a metal composite plate. A plurality of electromagnetic vibration devices are mounted on a mandrel of a roller body. By means of vibration mechanical energy generated by electromagnetic vibration, the roller body is made to vibrate inthe rolling process so as to break an oxide film on the contact surface of a bi-metal material, so that more fresh metal is exposed out of the bi-metal contact surface, the bonding area is enlarged, and the bonding strength of the bi-metal plate is improved. The electromagnetic vibration frequency can be adjusted according to the bonding strength of a plate blank, and the frequency of each electromagnetic vibrator can also be independently adjusted according to the edge crack condition of the plate till requirements are met. The electromagnetic vibration roller for rolling the metal compositeplate has the beneficial effects that the breaking degree of the oxide film on the contact surface of the bi-metal composite material is improved, the exposure rate of fresh metal is increased, the bonding strength is improved, edge cracks are restrained, and thus rolling production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of bimetal composite material rolling, and in particular relates to an electromagnetic vibrating roll for rolling a metal composite plate. Background technique [0002] With the development of modern science and technology, people continue to put forward higher requirements for the performance of materials. In most cases, it is difficult to use a single metal material to meet the performance and cost requirements of engineering structures. Due to the excellent properties of cladding metal and base metal, bimetallic composite panels are widely used in aerospace, mechanical power, electronic communication, home life and other aspects. [0003] In recent years, the rolled bimetallic clad plate is usually divided into cold rolling and hot rolling. After the production, the plate must be annealed, which will greatly increase energy consumption and reduce production efficiency. In addition, high rolling force d...

Problems solved by technology

[0003] In recent years, the rolled bimetallic clad plate is usually divided into cold rolling and hot rolling. After processing, the plate must be annealed, which will greatly increase energy consumption and reduce production efficiency.

In addition, high rolling force during cold rolling can easily lead to mill bounce and roll deflection

Hot rolling has many problems such as difficult size control, low strength index, large performance fluctuation range, poor surface quality, and excessive temperature will cause grain growth.
