Steelworks lossis Oxygen Converter
(Basic Oxygen Rauv: BOF)
Nws yog dab tsi? Nws yog pear-puab rauv lined nyob rau hauv nrog refractory cib uas refines thiab converts tus npua hlau los ntawm lub moj tej tawg rauv thiab seem hlau rau hauv hlau. Txog li 30 feem pua ntawm cov nqi hauv qhov cub hluav taws xob no tuaj yeem yog seem, tus so yog
pig hlau
Vim li cas thiaj siv tau? Cov BOF furnaces, uas tuaj yeem ua kom zoo dua ib pawg hauv 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.
BOFs 'kev ua haujlwm nrawm, tus nqi qis, thiab kev tswj tau yooj yim ua rau lawv muaj txiaj ntsig zoo dua li cov txheej txheem dhau los.
Nws ua haujlwm li cas? Cov khib nyiab yog tso rau hauv lub qhov cub, ces cov hlau molten los ntawm lub qhov cub tawg yog emptied. Los ntawm sab sauv los rau hauv ib lub lance uas txhaj cov pa ntawm lub siab kom ua rau cov tshuaj tiv thaiv uas cais impurities xws li gases thiab slag. Thaum refined, cov kua hlau yog nchuav rau hauv lub lauj kaub ntxiv cov ferroalloys thiab sib cais los ntawm slag.
