Smelting thiab kub dov txheej txheem ntawm Silicon steel ntawv

Cov hlau yog smelting thiab kub dov txheej txheem: molten hlau desulfurization → sab saum toj thiab hauv qab reblowing converter → nqus refining → nruam casting → 7 khib kub nruam dov. Cov hlau molten yuav tsum tau ua kom muaj zog desulfurized thiab slagged kev kho mob, thiab cov ntsiab lus S ntawm cov hlau molten sab nrauv yuav tsum tswj qis dua 30 × 10-6; Txiv qaub yog ntxiv thaum lub converter tso tawm mus ntxiv desulfurization tob; RH refining tuaj yeem tsis tsuas yog ua kom tiav alloying thiab txo C hauv cov hlau mus rau 30 × 10-6, tab sis kuj muaj ib qho me me ntawm desulfurization peev xwm; Nruam casting txais qhov loj bald ntev spout thiab argon foob, tundish slag npog, immersion nozzle rau tag nrho cov kev tiv thaiv casting; Txhawm rau tiv thaiv qhov overburning ntawm lub billet thiab lub cev qhuav dej ntawm lub cub tawg, lub cua sov kub tswj tau qis dua 1200 degree; Raws li qhov muaj pes tsawg leeg, ib qho tsim nyog 7- khib kub dov txheej txheem tau tsim, thiab cov coiling kub tau tswj siab tshaj 650 degree kom ntseeg tau tias cov microstructure nplej ntawm cov phaj kub dov yog ntxhib thiab sib xws [3].
