Lub Marten rauv thiab nws qhov tseem ceeb nyob rau hauv qhuav ntawm hlau

Lub tsev melting loj nyob hauv txoj kev lag luam hlau yog qhib hluav taws xob. Nws yog npaj rau steelmaking predetermined tshuaj nyob tus yeees thiab tej yam lub cev thiab cov neeg kho tshuab cov yam ntxwv. Qhib-hearth cub tawg, uas tau undergone ob peb muaj thiab kev siv technology tshiab revolutions, uas zus tau tej cov feem ntau complex steels, xws li alloyed.

Lub cub tawg qhib rau ntawm qhov qhib-hearth hom yog ib qho chaw ua kom pom ntawm qhov kev ua haujlwm ntawm kev ua haujlwm tshiab, uas muaj cov qauv hauv qab no:

• Qhov chaw ua haujlwm, uas suav nrog sab nrauv thiab sab pem hauv ntej phab ntsa.
• Lub hau nrog ntsug raws, uas cov roj thiab huab cua sib tov yog pub rau hauv cov chaw ua hauj lwm thiab cov combustion cov khoom raug tshem tawm ntawm nws.
• Roj thiab cua pliag, tsim los khaws thiab sib sau cov zauv loj loj ntawm melting hmoov av.
• Cov neeg tuaj yeem tuaj yeem ua kom muaj qhov kub thiab txias los ntawm cov cua sov thiab cua sib tov nrog lub tshav kub ntawm cov khoom seem hauv cov hluav taws uas tawm hauv cov chaw ua haujlwm.
• System changeover reversibly-regulating valve, tsim los hloov cov kev coj ntawm mov ntawm gaseous roj thiab cua sib tov nyob rau hauv cov ua hauj lwm qhov chaw, thiab siv sij hawm therefrom lub combustion khoom.
• Kub rov qab ua kom sov.
• Lub chim.

Martin cub hluav taws xob yog ib hom kab mob hauv nruab nrab, uas yog tib qho qauv tsim ntawm nws txoj cai thiab sab laug ntu ntawm txoj kab xaj. Kev thau khoom ntawm raw cov ntaub ntawv yog nqa los ntawm kev qhib tshwj xeeb - txhaws qhov rais, uas yog kaw los ntawm bolts, uas yog cov hlau phaj. Nyob rau ntawm phab ntsa nram qab ntawm lub tsev muaj lub qhov hluav taws xob, los ntawm qhov uas cov hlau tiav lawm ua ke rau hauv lub laub. Thaum lub sij hawm melting daig qhov hluav taws xob caking refractory av nplaum, uas sawv tawm ntawm kev tso tawm ntawm lub tiav lawm melt.

Qhib-hearth cub tawg tso cai yuav luag tag nrho cov hom ntawm cov pa roj carbon steels thiab ntau hom ntawm alloy steel. Tab sis kev siv ntau yam ntaub ntawv, uas tsim nyog rau txoj kev qhib-hearth, saturates molten hlau nrog ib tug tseem ceeb npaum li cas ntawm teeb meem impurities. Txawm hais tias ib feem me me ntawm cov khoom siv li cov tshuaj hnyuv ntxwm, phosphorus, arsenic thiab lwm cov ntsiab lus ua rau lub ntse deterioration nyob rau hauv cov khoom siv hlau ntawm cov hlau, txo cov yas zoo ntawm cov hlau, thiab muab nws ua rau ntau lub zog.

Rau qhov zoo ntawm cov khoom cua zoo hluav taws xob ua rau hluav taws xob hluav taws xob yog npaj. Tag nrho cov keeb kwm ntawm txoj kev loj hlob ntawm lub tshuab siv thiab hlau metallurgy ntsig mus rau ib tug nriaj rau cov qauv zoo ntawm cov hlau, kev txhim kho ntawm lawv mechanical, lub cev thiab tshuaj lom neeg. Thiab pub leejtwg ntawm lub siab tshaj plaws ntawm cov hlau lies nyob rau hauv nws cov tshuaj purity. Electrometallurgy yuav pab tau kom tau txais kev sib tw, thiab yog li ntawd, cov tshuaj zoo thiab cov phom. Cov kev thooj ntawm cov phom sij zoo yog cov ntxhiab nyob hauv cov hluav taws xob hluav taws xob.
