介绍当把冷的阳极块放入Hall-Heroult氧化铝反应槽的冰晶石电解质中时,热波穿过阳极块的内表面。由于现场的温度分布产生材料的热膨胀。阳极块上热膨胀的不同产生热应力。当炭素块掉入电解槽时,热 Introduction When a cold anode block is placed in a cryolite electrolyte in a Hall-Heroult alumina reaction cell, heat waves pass through the interior surface of the anode block. Thermal expansion of the material due to the temperature distribution in the field. Differences in thermal expansion on the anode block create thermal stresses. When the carbon blocks fall into the cell, heat
