摘　　要：焊接区域温度曲线是回焊炉焊接产品质量的重要指标。本文主要研究回焊炉焊接中心的炉温曲线,首先根据某次实验中的情况,基于热传导原理,建立回焊炉内部的温度分布模型,再运用牛顿冷却定律,建立焊接区域的温度分布模型。本文通过建立炉温曲线的模型为实际生产提供理论依据。The temperature curve of the welding area is an important indicator of the quality of the welding product of the reflow furnace. This article mainly studies the furnace temperature curve of the welding center of the reflow furnace. First, based on the situation in a certain experiment, based on the principle of heat conduction, the temperature inside the reflow furnace is established Distribution model,and then use Newton’s law of cooling to establish the temperature distribution model of the welding area. This article provides a theoretical basis for actual production by establishing a model of the furnace temperature curve.
