Device and method for preparing bimetal composite material through rapid electromagnetic induction heating

Abstract

The invention discloses a device and method for preparing a bimetal composite material through rapid electromagnetic induction heating. The device comprises a combining device, a heat preservation device, an automatic temperature measurement and control device, a cooling device and a traction device which are sequentially arranged from front to back. The combining device comprises a sealed box body, a mold filling device, a medium-frequency smelting furnace, a high-frequency induction heating coil and an argon protection device, and through grooves allowing steel plates to penetrate through are formed in the two longitudinal ends of the sealed box body. The lower end of the mold filling device is located in the sealed box body, a melt outlet in the lower end of the medium-frequency smelting furnace is connected with the upper end of the mold filling device, the high-frequency induction heating coil is located in the sealed box body and located on the front side of the mold filling device, and the argon protection device is mounted on the sealed box body. Compared with the prior art, the quality of the steel backing-antifriction copper alloy composite material can be effectively improved by regulating and controlling the temperature and time at different stages in the preparation process.

Description

technical field [0001] The invention relates to the technical field of double-metal clad materials, in particular to a device and method for preparing double-metal clad materials by rapid electromagnetic induction heating. Background technique [0002] Bimetal clad material is a new type of material that combines two metal pipes with different properties at the interface in a layered manner by using composite technology. Due to its advanced production technology and the combination of the characteristics of the two metals, the material is It breaks through the traditional technology in terms of performance and optimization, and has excellent characteristics that cannot be compared with a single metal. It has been widely used in aerospace, military weapons, transportation, electronic information and other fields. [0003] At present, there are many methods for preparing metal clad materials, which can be roughly divided into the following two categories according to the state...

Problems solved by technology

[0006] The powder metallurgy sintering and rolling composite method is used to obtain the bearing material with low structure density and poor interface bonding; there are problems such as casting defects and Pb element segregation in the static casting method; the centrifugal casting method and the particle induction centrifugal casting method have serious Pb element segregation and poor quality. Poor stability

[0007] The invention patent with the application number 200810150089.4 discloses a continuous casting thermal compound device and a method for preparing copper-lead alloy-steel bearing material. The heating device is induction heating and radiation heating. There is no heat preservation heating device, and the heating interval is long. The heating efficiency is low, and the solidification structure of the end layer and the morphology distribution of the lead-rich phase are easily affected by strong cooling
