Plat hlau

Steelworks lossis 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 cov khoom seem, vim li cas nws thiaj siv tau? Cov furnaces (BOF), uas tuaj yeem kho qhov nqi tsawg dua 45 feeb, hloov cov tsoos Siemens-Martin furnaces ntawm 1950s, uas yuav tsum tau tsib mus rau rau teev ua haujlwm ceev, tsawg dua cov nqi thiab yooj yim ntawm kev tswj BOFs muab nws muaj 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.

Hlau alloy
(Alloy hlau)
Kev sib xyaw ntawm cov hlau yog suav tias yog cov hlau alloy thaum feem pua ntawm manganese ntau dua 1.65%, feem pua ntawm silicon yog siab dua 0.5%, feem pua ntawm tooj liab yog ntau dua {{4} }. 6% lossis lwm yam tsawg kawg nkaus ntawm cov ntsiab lus
random xws li chromium, nickel, manganese, molybdenum los yog tungsten. Nws muaj peev xwm tsim tau ntau yam khoom tshwj xeeb rau cov hlau los ntawm kev hloov cov no
cov ntsiab lus hauv "daim ntawv qhia".

High Carbon Steel
(High-Carbon Steel)
Hlau nrog ntau dua 0.3% carbon. Qhov ntau dua cov carbon yaj nyob rau hauv cov hlau, qhov tsawg moldable thiab harder cov hlau ua. Lub hardness ntawm high carbon steel ua rau nws haum rau plow discs, shovels, txiav npoo
txiav los yog lwm yam kev siv siab hnav.
