Steel Mill los yog Oxygen Converter
(Basic Oxigen Rauv: BOF)
Nws yog dab tsi? Nws yog ib puag ncig rauv lined nyob rau hauv nrog refractory cib uas refines thiab converts molten npua hlau los ntawm lub moj tej tawg rauv thiab seem hlau rau hauv hlau. Txog li 30% ntawm cov khoom thauj hauv lub qhov cub no tuaj yeem yog seem, tus so yog
nrum hlau
Vim li cas thiaj siv tau? Cov furnaces (BOFs), uas tuaj yeem kho qhov nqi tsawg dua 45 feeb, hloov cov tsoos Siemens-Martin furnaces ntawm xyoo 1950, uas yuav tsum tau tsib mus rau rau teev los ua cov hlau.
Kev ua haujlwm sai, cov nqi qis dua thiab kev tswj tau yooj yim ntawm BOFs muab nws qhov txiaj ntsig zoo dua li cov txheej txheem dhau los.
Nws ua haujlwm li cas? Cov seem yog muab tso rau hauv lub qhov cub, ces cov hlau molten los ntawm lub qhov cub tawg yog emptied. Lub lances nqis los ntawm sab saum toj thiab txhaj cov pa oxygen ntawm lub siab kom ua rau muaj tshuaj lom neeg uas cais cov impurities xws li gases thiab slag. Thaum ua kom zoo dua, cov kua hlau yog nchuav rau hauv lub lauj kaub, ntxiv cov ferroalloys thiab sib cais los ntawm slag.
