通过对罩式退火机组现状分析,决定对LOI加热罩的内衬喷涂纳米高温节能涂料,以提高热发射率,增加辐射传热和放热的速度,降低加热罩外壁温度,延长加热罩内衬使用寿命。最终达到降低吨钢介质成本消耗和节能的目的。
Through the analysis of the status of the hood annealing unit, it is decided to spray the lining of the LOI heating hood with nano-high-temperature energy-saving coating to increase the thermal emissivity, increase the heat transfer and exothermic rate, lower the outer wall temperature of the heating mantle, Service life. Finally achieve the purpose of reducing the cost per ton of steel medium and saving energy.
