Industrial furnace is a nonlinear system, has its non-linear characteristics, due to the diversity of the heating mode, the heating mode, the furnace structure and process parameters, the new all-fiber furnace, resulting in industrial furnace automation diversity. Currently as a steel power of Japan, the United States has expert systems and fuzzy control technology in steel rolling industrial furnace combustion control, and has made significant economic benefits. In this regard our country has done a lot of research, heat treatment furnace trolley, put a lot of money, but the success of small, electric stove, only in a few mills has been applied. In the mathematical model furnace temperature control aspects have been more successful cases abroad, they use the Fourier heat equation to calculate the actual state of the heating furnace billet, and the corresponding mathematical model formula. Compared with electrically heated vacuum furnaces, vacuum furnace gas What are the advantages? Higher productivity and high thermal efficiency; low operating cost; maintenance is simple and maintenance; electric heating vacuum furnace having all the features. Compared with the batch vacuum furnace, semi-continuous production efficiency vacuum furnace can be increased by 25% -30%, continuous vacuum furnace production efficiency can be increased by 40% to 50%, in addition to at least a semi-continuous and continuous vacuum furnace heat loss , high thermal efficiency, energy-saving materials (gas, oil, etc.), low production costs. _ Tempering furnace heat treatment furnace experiments Longkou (Online) _ furnace experiments Longkou Furnace by.
