1. Kev khiav hauj lwm kub ntawm ib lub steel zeb Refining rauv
Lub steel zeb refining rauv yog ib qho tseem ceeb ntawm cov khoom siv nyob rau hauv cov txheej txheem steel, thiab nws cov kev khiav hauj lwm kub ncaj qha cuam tshuam steel zoo thiab ntau lawm efficiency. Feem ntau hais lus, qhov kev ua haujlwm kub ib txwm rau cov hlau zeb refining rauv yog nruab nrab ntawm 1500℃thiab 1700 degree. Qhov ntsuas kub no yog txiav txim siab los ntawm qhov chaw melting ntawm cov hlau thiab cov tshuaj tiv thaiv cov tshuaj tiv thaiv uas yuav tsum tau ua thaum lub sijhawm ua kom zoo.
Nyob rau hauv qhov ntsuas kub no, cov hlau tuaj yeem yaj tag nrho thiab cov tshuaj lom neeg hauv lub qhov cub tuaj yeem ua haujlwm zoo, tshem tawm cov impurities ntawm cov hlau, txhim kho nws cov purity thiab txhua yam khoom. Tsis tas li ntawd, qhov ntsuas kub tsim nyog ua kom cov thermal efficiency thiab ruaj khov ntawm refining rauv, txo kev siv hluav taws xob thiab cov khoom siv tsis ua haujlwm.
Nws yog ib nqi sau cia hais tias qhov tshwj xeeb kev khiav hauj lwm kub ntawm ib tug steel zeb refining rauv kuj raug cuam tshuam los ntawm ntau yam, xws li rauv hom, tus nqi tsim nyog, thiab cov txheej txheem ntau lawm. Yog li ntawd, nyob rau hauv qhov tseeb ntau lawm, steel mills yuav kho cov refining rauv ua hauj lwm kub kom tsim nyog raws li lawv tej yam kev mob thiab cov txheej txheem yuav tsum tau.
2. Qhov kub thiab txias ntawm Refining Rauv Cov Plua Plav Sau
Refining furnace plua plav collectors yog ib qho tseem ceeb ntawm cov khoom tiv thaiv ib puag ncig hauv cov txheej txheem steel dov thiab refining. Lawv lub luag haujlwm tseem ceeb yog khaws thiab kho cov pa taws thiab cov pa phem uas tsim tawm hauv lub qhov cub, tiv thaiv lawv los ntawm kev ua phem rau ib puag ncig thiab tib neeg kev noj qab haus huv. Cov plua plav collector qhov kub thiab txias kuj yog qhov tseem ceeb cuam tshuam rau nws cov kev ua tau zoo.
Feem ntau hais lus, qhov kub ntawm qhov nkag ntawm lub qhov cub ua kom zoo dua cov khoom siv plua plav yog qhov siab, feem ntau nyob ib puag ncig ntau pua degrees Celsius. Tus nqi tshwj xeeb yog nyob ntawm tus nqi ntawm cov pa luam yeeb tsim nyob rau hauv lub cub tawg thiab cov qauv tsim ntawm cov khoom siv plua plav. Qhov hluav taws xob kub, ntawm qhov tod tes, yog qhov qis, feem ntau yog li ntawm ntau kaum rau ntau tshaj ib puas degrees Celsius.
Txhawm rau kom ua haujlwm tau zoo ntawm cov plua plav collector thiab txuas ntxiv nws lub neej kev pabcuam, steel mills siv ntau yam kev ntsuas los tswj cov plua plav collector qhov kub thiab txias. Piv txwv li, preheating los yog txias cov cuab yeej raug ntsia rau ntawm cov plua plav collector inlet kom tswj qhov kub ntawm cov pa taws nkag mus rau hauv cov plua plav collector. Tsis tas li ntawd, cov khoom siv plua plav tau raug ntxuav tas li thiab tswj xyuas kom tsis txhob muaj kev cuam tshuam sab hauv.
Hauv cov ntsiab lus, qhov kub thiab txias ua haujlwm ntawm lub qhov cub steelmaking thiab qhov kub thiab txias ntawm lub tshuab nqus plua plav yog qhov tseem ceeb uas yuav tsum tau saib xyuas thiab tswj xyuas thaum lub sij hawm tsim cov hlau. Los ntawm kev kho kom zoo thiab ua kom zoo dua cov ntsuas kub no, tsis tsuas yog tuaj yeem txhim kho cov khoom zoo thiab kev ua haujlwm zoo, tab sis kev siv hluav taws xob thiab kev ua qias tuaj ib puag ncig tuaj yeem txo.
