Kev piav qhia
Kev cia siab rau daim ntawv thov ntawm high-carbon silicon: Hloov steelmaking nrog siab [si] hlau yog nquag spattering thiab lwm yam teeb meem. Silicon muaj qhov muaj zog affinity rau oxygen, nyob rau hauv thaum ntxov theem ntawm converter oxygen tshuab uas yog pib ntawm oxidation thiab tso tawm ib tug loj npaum li cas ntawm tshav kub, uas ua rau converter tshuab ntawm kub nce ceev heev.
Vim tias slag ntau dhau lawm, cov slag ntau ntau, thiab cov slag ua npuas ncauj yog qhov hnyav, nws yooj yim heev ua rau tawg sputtering nyob rau hauv lub converter, ua rau kom poob ntawm cov hlau, thiab txawm hlawv cov cuab yeej nyob rau hauv lub cub tawg, ua rau kom tawg. ib puag ncig muaj kuab paug loj. Hauv kev siv cov pa roj carbon monoxide siab ua ntej cov xwm txheej ntawm cov hlau thiab steel mills, feem ntau yog los ntawm cov hlau pretreatment kom txo tau cov ntsiab lus ntawm cov hlau, kom ua tiav cov slag tsawg los yog tsis muaj slag ua haujlwm, kom txo tau cov converter spatter. Hlau pretreatment feem ntau siv sintered ore, pellet ore, nplua nuj ore hmoov thiab hlau oxide daim tawv nqaij raws li tus neeg sawv cev desilicone, los ntawm kev txau thiab nplawm, yog li ntawd si oxidation los ua slag, thiab thaum kawg lub slag nuv ntses tawm.
Lub si yog txo mus rau ib tug ntau yam uas yuav tsum tau tshuab, thiab ces smelting lub converter yog nqa tawm; Lwm txoj kev kho mob yog nrum lub siab si molten hlau rau hauv npua hlau, thiab tom qab ntawd ua ke nrog cov hlau seem rau hauv qhov cub. High carbon silicon technology kom ua tiav cov ntsiab lus: siab silicon hlau smelting muaj loj spattering, slag ntim tsub kom hlau poob, thiab txawm hlawv cov khoom nyob rau hauv lub cub tawg, uas ua rau ib puag ncig muaj kuab paug thiab ib tug series ntawm teeb meem.

High-carbon silicon rau 50 # steel kom nce silicon thiab carbon txoj kev, nyob rau hauv cov hlau mus rau lub steel dej mus rau hauv ib feem ntawm lub siab silicon hlau dej, ua kom tag nrho cov kev siv ntawm high silicon hlau dej carbon thiab silicon rau cov muaj pes tsawg leeg, txoj kev zoo txo. 50 # steel txheej txheem ntawm carbon hmoov thiab silicon noj, thaum txhim kho cov hlau tawm los, txo cov khoom siv hlau. Txhawm rau kom ua tiav lub hom phiaj saum toj no, nrog cov pa roj carbon siab thiab silicon kev daws teeb meem yog raws li hauv qab no:
1) lub converter yog loaded nrog hlau thiab seem, tswj tag nrho cov loading rau tus qauv loading ntawm 92 ~ 95%, seem piv ntawm 6 ~ 15%;
2) lub converter tawm ntawm steel kub tswj ntawm 1610 ~ 169{5}} degree, qhov kawg ntawm kev tso tawm steel carbon tswj ntawm 0.07% ~ 0.20%;
3) tawm ntawm cov txheej txheem pib ntawm cov txheej txheem ntawm kev sib koom ua ke nrog cov hlau ntws ntawm ferro aluminium thiab manganese kom deoxidize; 4) tawm ntawm cov hlau los koom nrog Alloy; zawv zawg qhov hluav taws xob slag thaiv;
5) tawm ntawm steel ladle tsheb tsav mus rau lub steel txais ncua, yuav tsum tau npaj ua ntej ntawm high-silicon hlau dej rau hauv lub ladle; nyob rau hauv lub high-silicon hlau dej muaj cov nram qab no luj feem pua ntawm cov Cheebtsam: [c] 4.3 % rau 5.0%, [si] Ntau dua lossis sib npaug li 1.2%, [mn] 0.1% rau 0.3%, [p] Tsawg dua lossis sib npaug rau 0.12%, [s] Tsawg dua lossis sib npaug rau 0.020%, [as] Tsawg dua lossis sib npaug rau 0.015%. 0.015% ib.
