瑞士温特图尔市的一冶金工厂对这一技术进行了试验研究。试验时，将氦气注入水冷模模壁与铸锭之间的间隙中，考察它对金属凝固、缩孔大小等的影响。试验发现，铸徒向模壁的传热取决于间隙中所充氦气的压力水平。在最佳操作条件下，使用氦气后，有20％以上的热量迅速被冷却水带 A metallurgical plant in Winterthur, Switzerland, piloted the technology. During the test, helium gas was injected into the gap between the water-cooled mold wall and the ingot to examine its effect on the solidification of the metal and the size of the crater. It has been found experimentally that the heat transfer from castor to mold wall depends on the pressure level of helium in the gap. Under optimum operating conditions, more than 20% of the heat is rapidly cooled by the cooling water after using helium
