Phosphorus Thiab Hlau

Tam sim no,ferrophosphorusFeem ntau yog los ntawm kev lag luam daj phosphorus thiab yog cov khoom los ntawm cov phosphorus daj uas tsim los ntawm txoj kev siv hluav taws xob. Txij li txhua tuj ntawm cov phosphorus daj tuaj yeem tsim tau txog li 200 kilograms ntawm cov hlau phosphorus, nws cov zis tsawg heev thiab tsis tuaj yeem ua tau raws li cov kev xav tau ntawm kev tsim kho kev lag luam metallurgical thiab tshuaj.

Nyob rau hauv xyoo tas los no, qee cov neeg tau siv hlau ore thiab phosphate ore ua raw khoom los tsim cov hlau phosphate los ntawm kev txo cov coke thiab melting nyob rau hauv lub cub tawg siv lub spherical kub blast rauv (kub moj tej tawg kub 700-800 degree ). Txawm li cas los xij, vim qhov corrosion ntawm silicon tetrafluoride roj thaum lub sij hawm tsim cov txheej txheem no, thiab cov phosphorus vapor thiab generated hlau phosphate tuaj yeem yooj yim thaiv cov kav dej thiab cov khoom siv, cov khoom siv ntau lawm tsis ua haujlwm zoo; phosphorus cov ntsiab lus nyob rau hauv cov hlau-phosphorus cov khoom tsim yog tsawg dua 23%, Tsawg tso zis thiab siab zog noj.

Xyoo 1669, G. Brand nrhiav tau phosphorus. Xyoo 1826, P. Berthier tau tsim cov hlau phosphorus. Nyob rau hauv 1868, C. Brison patented zus tau tej cov phosphorus thiab phosphoric acid nyob rau hauv lub blast furnace. Xyoo 1929, qhov cub tawg rau kev tsim cov phosphoric acid kub hauv Victor, Tebchaws Asmeskas, tau muab tso rau hauv kev ua haujlwm. Nyob rau xyoo 1870, patents tau tshwm sim rau kev siv hluav taws xob rau hluav taws xob rau smelt phosphorus thiab phosphorus hlau. Xyoo 1925, thawj 3000kW peb-theem hluav taws xob rauv tau tsim hauv Bitfield rau kev tsim cov phosphorus. Nyob rau hauv lub neej yav tom ntej, hluav taws xob furnaces yuav dhau los ua cov cuab yeej tseem ceeb rau kev tsim phosphorus. Ferrophosphate yog ib qho khoom los ntawm cov khoom daj phosphorus.
