ʻO nā kapuahi hau he ʻāpana waiwai nui i ka ʻoihana hou. Hiki iā ia ke hoʻokō i nā kaʻina hana paʻakikī ʻaʻole hiki ke mālama ʻia e nā mea hana wela ʻē aʻe, ʻo ia hoʻi ka hoʻoheheʻe ʻana a me ka hoʻomaʻamaʻa ʻana, ka hoʻoheheʻe ʻana i ka vacuum, ka hopena paʻa a me ka manawa, ka sintering vacuum, ka hoʻomaʻamaʻa wela kemika a me nā kaʻina hana uhi. Hiki i kona wela wela ke piʻi i ka 3000 ℃, a ʻo ka tungsten a me ka molybdenum he maikaʻi ke kūpaʻa kiʻekiʻe kiʻekiʻe a me ka coefficient hoʻonui haʻahaʻa haʻahaʻa, no laila hoʻohana pinepine ʻia lākou e like me kekahi mau mea i loko o ka umu.
ʻO ka mea maʻamau, inā ʻoi aku ka kiʻekiʻe o ka wela o ka umu ma mua o 1100 degere Celsius, e manaʻo ʻia ka molybdenum a i ʻole tungsten e like me ka pale wela (me nā ʻaoʻao ʻaoʻao a me nā pale uhi luna a me lalo): ʻo nā ʻāpana insulation wela i ka umu, ke kuleana nui o ka molybdenum. tungsten reflector pale a me ka luna a me ka lalo uhi mea e ālai a reverberate i ka wela i loko o ka umu ahi. ʻO ka tungsten a me ka molybdenum heat insulation plate ka mea maʻamau i hana ʻia me ka riveting, hiki ke hoʻopaʻa ʻia a uhi ʻia paha. Hiki ke hoʻohana ʻia nā papa ʻāwīwī, nā ʻāpana U-like a i ʻole nā puna uea molybdenum a me nā spacers ma waena o nā pale o kēlā me kēia papa, a hoʻopaʻa ʻia me ka uea molybdenum a i ʻole nā uea tungsten a me nā wili.
