Kev cuam tshuam ntawm smelting txheej txheem ntawm lub zog txuag ntawm hlau melting rauv

1 Cov khoom xyaw tsim nyog

Kev tswj xyuas kev tshawb fawb ntawm tus nqi yog qhov tseem ceeb los txhim kho cov khoom siv hluav taws xob ntawm cov hlau melting rauv thiab txo cov kev siv zog.

Sim kom tsis txhob ncua sij hawm smelting vim qhov kev hloov ntawm cov khoom muaj pes tsawg leeg, thiab tiv thaiv cov hlau (steel) los ntawm kev khawb vim tsis tsim nyog muaj pes tsawg leeg, nce cov khoom siv thiab kev siv hluav taws xob.

Tus nqi yuav tsum tau muab cais raws li cov tshuaj muaj pes tsawg leeg, cov ntsiab lus impurity thiab lumpiness, txiav loj thiab ntev seem steel, thiab conditionally kam nrog lub teeb thiab nyias cov ntaub ntawv los xyuas kom meej tus nqi them thiab txo lub sij hawm smelting. Lub lumpiness ntawm tus nqi yuav tsum sib haum nrog lub zaus ntawm lub hwj huam mov. Qhov zaus ntawm cov khoom siv hluav taws xob siv los ntawm cov hlau melting rauv txo qis nrog qhov nce ntawm qhov cub muaj peev xwm. Qhov induced tam sim no nkag mus tob txheej thiab geometrical qhov ntev ntawm tus nqi hlau yog zoo sib xws (thaum txoj kab uas hla ntawm tus nqi hlau / qhov tob ntawm induced tam sim no nkag> 10, lub cub tawg muaj qhov zoo tshaj plaws hluav taws xob efficiency) kom luv lub sij hawm cua sov, nce tus nqi cua sov, thiab txo hwj chim noj. Piv txwv li, 500Hz intermediate zaus fais fab mov yog tsim rau 8cm, thaum 1000Hz intermediate zaus fais fab mov yog tsim rau 5.7cm.

2 Ncua sij hawm smelting tsis tu ncua

Chav tsev siv hluav taws xob muaj ntau yam ua nrog txoj kev smelting. Cov ntaub ntawv qhia tau hais tias, coj mus rau hauv tus account lub zog poob yuav tsum tau rau slag melting thiab overheating, thaum lub siab heev hlau melting rauv yog txias pib, chav tsev zog noj yog 580KW · h / t, thiab thaum lub kub kub ua hauj lwm, lub hwj chim unit. Kev siv yog 505-545KW · h / t. Yog tias kev ua haujlwm pub noj tsis tu ncua, chav tsev siv hluav taws xob tsuas yog 494KW·h / t.

Yog li ntawd, yog tias ua tau, nws yog ib qho tsim nyog yuav tau npaj cov concentrated thiab nruam smelting kom ntau li ntau tau, sim ua kom muaj cov smelting rauv, ncua sij hawm smelting tsis tu ncua, txo tus naj npawb ntawm qhov cub txias smelting, thiab txo hwj chim noj.

3 Kev ua haujlwm smelting tsim nyog

(1) Kev tshawb fawb;

(2) Siv lub zog tsim nyog;

(3) Siv cov cuab yeej ua ntej ua ntej lub cub tawg tsim nyog los tswj cov nqi ntxiv tom ntej txhua zaus. Saib xyuas thiab phaus nquag txhawm rau tiv thaiv tus nqi ntawm “tsim lub tsev”. Nyob rau hauv no smelting ua hauj lwm, qhov kub yog tsa rau ib tug luv luv lub sij hawm ua ntej pouring, thiab molten hlau yog khaws cia nyob rau hauv ib tug qis kub nyob rau hauv lub so ntawm lub sij hawm, uas yuav txo tau cov corrosion ntawm high-temperature molten hlau nyob rau hauv lub cub tawg. lub neej kev pab cuam ntawm lub cub tawg, thiab txo hwj chim noj.

(4) Siv cov cuab yeej ntsuas kub thiab ntsuas kev ntseeg siab;

(5) Txhawb kev nyeem ntawv ncaj qha thiab txo lub sijhawm ntawm kev tshuaj xyuas cov khoom pov thawj.

(6) nruj me ntsis tswj lub cub tawg kub ntawm steel thiab molten hlau;

(7) Muab tso rau hauv ib lub sij hawm thiab txaus npaum li cas ntawm cov cua sov preservation thiab npog tus neeg sawv cev slag remover. Tom qab cov hlau molten raug xa mus rau lub ladle, qhov tsim nyog ntawm rwb thaiv tsev npog tus neeg sawv cev thiab cov slag tshem tawm yuav tsum tau muab tso rau hauv tam sim ntawd, uas tuaj yeem txo qhov kub poob thaum lub sij hawm molten steel sedation pouring txheej txheem, thiab tapping kub yuav tsum tau txo kom tsawg. siv zog.

4 Ntxiv dag zog rau kev tswj hwm thiab kev saib xyuas cov khoom siv smelting kom txuag hluav taws xob thiab txo kev siv

Txhim khu kev tswj ntawm cov hlau melting rauv, standardize cov txheej txheem kev khiav hauj lwm yuav tsum tau ntawm lub cub tawg kev tsim kho, sintering, smelting, thiab cov txij nkawm ntawm lub intermediate zaus fais fab mov, zoo txhim kho lub hnub nyoog ntawm lub cub tawg, ua kom lub cev ua hauj lwm ntawm lub intermediate zaus fais fab mov. , thiab txo lub zog noj ntawm smelting.
