Experiment Analysis of Thermal Stress in the Cooling Wall of Blast Furnace
-
摘要: 采用脆性涂層法和電阻應變法實際測量了高溫狀態下高爐冷卻壁的應力和應變.實測結果表明:由于冷卻水管的非均勻布置,冷卻壁中心位置應力較高,而四周應力較低,高爐冷卻壁的應力分布,與有限元的應力分布計算結果的趨勢和數量級相同.這種測量方法的應用為應力應變的理論計算提供了一種新的校驗方法.Abstract: The measurement result of actual strain and stress of the cooling wall in the blast furnace at high temperature state was obtained by the method of brittle coating and strain gauge line.Its showed that the stress is higher in central position than in the peripheral position because of the nonuniform distribute of water pipe.The tendency and order of calculation result is the same as the measurement.Its application leads to a new measurement method for calibrating the theory calculation result of the stress and strain.
