Khoom Description

Ferrotungsten yog smelted nyob rau hauv lub cub hluav taws xob. Vim nws cov ntsiab lus melting siab, nws tsis tuaj yeem tso tawm hauv cov kua dej, yog li nws yog tsim los ntawm txoj kev agglomeration lossis txoj kev rho tawm hlau. Ua ntej xyoo 1930, me me (100-500 kVA) ib zaug-theem hluav taws xob arc rauv feem ntau yog siv rau kev sib xyaw ua ke. Tom qab ntawd, peb-theem hluav taws xob rauv tau siv, thiab txoj kev rho tawm hlau tau tsim.

Muaj ntau cov tungsten mines nyob rau hauv Jiangxi, Hunan thiab Guangdong hauv Suav teb, nrog reserves accounting rau 60 mus rau 70% ntawm lub ntiaj teb reserves. Los ntawm 1936 txog 1938, ib tsob nroj ferrotungsten tau npaj los tsim hauv Ji'an, Jiangxi Province, thiab ob lub 2,000 kVA peb-theem hluav taws xob furnaces uas siv txoj kev agglomeration raug ntsia. Cov nroj tsuag tau pib ua tiav, tab sis tom qab ntawd raug tso tseg vim muaj kev cuam tshuam los ntawm Anti-Japanese War. Txij li thaum xyoo 1955, ferrotungsten tau tsim los siv 3,500 kVA hluav taws xob rauv siv txoj kev rho tawm hlau.tungsten hlauyog dav siv nyob rau hauv zus tau tej cov cuab yeej thiab machinery.
