In this paper, a mathematical model of heat transfer in tube annealing furnace, in which some parameters are confirmed through the embedded thermocouple experiments is presented.
The leakage current must be returned to the source, it will flow through any available thermocouple conductor, line pipe, pipeline, water or earth went to the source.
漏泄电流必需前往至源极，它将流经任何热电偶可用的导体、线管、管道、水或大地前往到源极。
