Keeb kwm kev loj hlob ntawm iav hluav taws xob melting rauv
Nyob rau hauv 1902, Voelker tau txais ib qho yooj yim patent, cov ntsiab lus ntawm uas yog siv lub tshav kub generated los ntawm cov ndlwg ntawm hluav taws xob tam sim no los ntawm cov iav batch kom yaj iav. Nrog rau kev txhim kho tas mus li thiab kev txhim kho ntawm lub tshuab hluav taws xob tsim thiab cov khoom siv hluav taws xob, cov txheej txheem hluav taws xob melting no tau siv dav. Los ntawm 1920 txog 1925, Norwegian Raeder siv graphite electrodes kom ua tiav tag nrho cov hluav taws xob melting ntawm iav. Xyoo 1925, Corneljus hauv Sweden tau siv lub tshuab hluav taws xob no los tsim cov iav amber thiab iav ntsuab. Lub tshuab hluav taws xob melting rauv txais cov txheej txheem pub mis nyias nyias, thiab cov ntaub ntawv batch ntab rau saum npoo ntawm cov iav molten. Thaum lub tshuab hluav taws xob melting rauv yog muab tso rau hauv kev tsim khoom, nws tau nruab nrog lub tshuab hluav taws xob ib ntus. Thaum cov iav kua theem npog cov electrode, lub qhov cub npog raug tshem tawm. Cov electrode siv yog ib qho loj hlau thaiv. Vim tias cov hlau electrode ua rau cov iav muaj xim, lub qhov cub no tsuas yog siv los yaj cov xim iav, thiab cov nyhuv yog qhov zoo heev. Thaum lub sijhawm ntawd, nws tuaj yeem ncav cuag 1.40kWh / kg iav, yog li kev ua haujlwm zoo li no tuaj yeem ua tau rau thaj chaw uas muaj nqi hluav taws xob tsawg. Qee lub tshuab hluav taws xob no tau ua haujlwm txog xyoo tas los no. Thaum lub sijhawm xyoo 1932 txog 1940, Ferguson tau siv lub "T"-zoo li hluav taws xob melting rauv kom nquag koom nrog kev tshawb fawb ntawm hluav taws xob melting.
Thaum Tsov Rog Thoob Ntiaj Teb thib Ob, Borel hauv Switzerland tau ua ntau yam kev tshawb fawb thiab kev tsim kho ntawm hluav taws xob fusion, aiming los daws qhov teeb meem ntawm roj tsis txaus. Boller txoj haujlwm tau ua tiav thiab txhawb nqa los ntawm Fabkis lub tuam txhab St. Gobain, uas kuj tau ua haujlwm zoo ntawm kev txhawb nqa hluav taws xob.
Tom qab Tsov Rog Ntiaj Teb Zaum II, tib neeg pib xav txog molybdenum electrodes. Lub tshuab electrode tsim los ntawm Penberthy siv molybdenum rods. Xyoo 1952, kev lag luam iav tau pib siv dav hauv kev txhawb nqa hluav taws xob thiab tag nrho hluav taws xob yaj. Lwm qhov yog lub phaj molybdenum electrode tau npaj los ntawm Gell thiab Hann hauv xyoo 1956.
