Results are provided for a study of diatomite of the Il’insk field (Sverdlovsk region) for preparation of unmolded insulation materials and their use as heat insulating materials in crucibles with molten aluminum. Use of diatomite as a heat insulating material makes it possible to reduce power consumption during holding molten aluminum in the resistance furnace crucible, prevents development of hydrogen porosity, and does not lead to melt saturation with silicon.

铝合金用非成型硅藻土基隔热材料

提供了研究结果，研究了伊林斯克油田（斯维尔德洛夫斯克州）的硅藻土，该硅藻土用于制备未模制的隔热材料，并将其用作具有熔融铝的坩埚中的隔热材料。使用硅藻土作为绝热材料，可以减少在将熔融铝保持在电阻炉坩埚中时的功耗，防止氢孔隙的产生，并且不会导致硅熔体饱和。
