Study on temperature control and composite properties of titanium and aluminum heterogeneous temperature rolling

摘要:

为实现钛铝异温轧制钛板电磁感应加热时温度分布更均匀,设计不同的感应加热线圈组对钛板进行加热,使用有限元模拟了电磁感应加热中感应线圈的结构参数对温度场的影响,通过调节感应加热参数将钛板宽度方向温差控制在50℃以内,形成较均匀的钛板温度。对钛板进行感应加热和测温实验,在较短时间的加热时长下形成了平均温度635℃,温差45℃以内的钛板温度,验证了仿真结果的正确性。对均匀性较好的高温钛板与室温铝合金板进行异温轧制,制备出界面剪切强度为63.3MPa的钛/铝复合板,并对制备出的钛/铝复合板结合性能的分布受温度均匀性的影响做了分析。

Abstract:

In order to achieve a more uniform temperature distribution during electromagnetic induction heating of titanium plate rolled at different temperature of titanium and aluminum, different induction heating coil sets are designed to heat the titanium plate, and the influence of the structural parameters of the induction coil on the temperature field in electromagnetic induction heating is simulated by using finite elements, and the temperature difference between the width of the titanium plate is controlled within 50 °C by adjusting the induction heating parameters to form a more uniform temperature of the titanium plate. The induction heating and temperature measurement experiments of the titanium plate were carried out, and the average temperature of the titanium plate was formed under a short heating time of 635 °C, and the temperature difference within 45 °C was formed, which verified the correctness of the simulation results. A titanium/aluminum composite plate with an interface shear strength of 63.3MPa was prepared by rolling the high-temperature titanium plate and the room-temperature aluminum alloy plate with good uniformity, and the distribution of the bonding performance of the prepared titanium/aluminum composite plate was analyzed by temperature uniformity.
