热管系统作为连铸结晶器的试验研究

将热管系统的蒸发器作为连铸结晶器，通过测试蒸发室及熔融室内的温度，揭示热管运行温度和熔融室温度的关系。结果表明：在普通环境温度下和物质熔融温度为160℃时．热管工作温度为50-70℃，热管系统蒸发器面积和冷凝器面积之比从1：15增加到1：30时。热管工作温度降低较快，下降约23％；当面积比从1：30增加到1：60时，下降约8％：将热管系统运用于连铸生产时．增大热管系统的冷凝器面积，可以降低热管工作温度。但降低程度随面积比的增大而减小；当用于镁合金连铸时，热管的运行温度将超过100℃．

Experiment on Continuous Casting Mold Used in Heat-pipe System

The heat transfer performance of heat-pipe system as a continuous casting mold is studied in the experiment, The relationship of heat pipe operating temperature and the melting room temperature by means of testing the temperature of evaporation room and melting room are presented. Experimental results show that the material melting temperature is about 160℃, the working temperature of heat pipe is in the range of 50 - 70℃, and the working temperature of heat pipe decreases rapidly with evaporator--condenser area ratio changing from 1：15 to 1：30. and the temperature is dropped by about 23%, while the area ratio changing from 1：30 to 1：60, the operating temperature of heat pipe is reduced by about 8% . Experimental results also show that the operating temperature of heat pipe can be reduced with the increasing of condenser area of the beat pipe system used in continuous casting production, but reduced rate decreases. The operating temperature of heat pipe will exceed 100 ℃ when the heat pipe system is used in the magnesium alloy casting.
