ʻO ka umu wela wela ka mea nui no ka hoʻolei ʻana, forging a me ka hale hana mālama wela.
ʻO nā lako, ʻo ia ka hoʻoheheʻe ʻana o ka metala, e like me ka hana nui o ka forging pre-forging heating treatment furnace no ka hoʻololi ʻana i ka wela, ka ʻōwili ʻana, ke kuʻi ʻana, ka mālama ʻana i ka wela (quenching), ka welding a me nā kaʻina hana ʻē aʻe o ka inductive induction heat, medium frequency furnace piʻi. i ka inverter thyristor capacitor resistance absorption e ka wai-cooled resistors, ma ke ano he kumu wai ka mea e pale ai. Hoʻohana ʻia ka pale ʻana o ka SCR i kekahi manawa pale pale alumini gula, vitreous enamel wirewound resistors.
