Furnace of LF steel bag is to use electric arc to heat fine equipment of the technology, it is the molten steel park in the Chu Lian in general steel-making furnace special steel bag has refined facility. The characteristic of LF furnace is undertake by 3 electrode; heats through electrode on one hand burying arc to heat build; of tall alkalinity reducing slag to undertake composition of deoxidization, to decoke, molten steel adjust on the other hand etc. To make molten steel and slag are contacted adequately, stimulative fine reaction makes molten steel temperature even, the bottom inbreathe inert gase that wraps in steel (argon is angry) have mix, thereby the alloy that enroll steel includes is achieved inside molten steel change equably.
The structure of LF finery
LF finery heats by electrode system, alloy and system of feed in raw material of broken bits makings, bottom breathes freely the brick boasts argon agitate system, measure the lukewarm sampling system, system that feed silk, furnace lid cooling system, remove dust system and control system composition. The position that uses fireproof data in these structures has: LF finery roof (furnace lid) , fine steel bag, bottom blows gas to breathe freely brick and slide of the bag intermediate.
